Foreword
Thank you for purchasing an Axe-Fx II, one of the most powerful musical instrument processors
ever produced. Please take the time to read through this manual to become acquainted with
the Axe-Fx II.
Thinking back to a date when the first Axe-Fx units rolled off the line back in 2006, it would
have been a challenge to predict the scale of what was to follow that the product would be
such a worldwide success that we would have a hard time keeping it in stock; that musicians
would rally around the unit, from online Axe-evangelists to the worlds most celebrated pro
players; that wed soon be writing the foreword to a manual for the sequel: the Axe-Fx II.
Nevertheless, the Axe-Fx II is here. Advances in technology and knowledge, along with the
shared insights of our community, have allowed us to design and produce a next-generation
product that represents a giant step forward. If you owned a Standard or an Ultra, we think
youll be very impressed with all the updates, additions and improvements. If youre new to the
Axe-Fx family, this is an incredible place to start.
It has been said that the Axe-Fx restored digital to its rightful place as the superior solution to
musical effects processing. Every aspect of the Axe-Fx II has been designed to deliver the latest
word in this commentary. It has twice the power of the Axe-Fx Ultra (while even the older
Standard still has more horsepower under the hood than any competitor). For the player, this
means better sound, smarter features, and improved performance.
In 2014 we introduced the Axe-Fx II XL, with upgraded/expanded memory and peripherals. We
think it is the best of our products ever, and we hope you agree.

WHATS NEW
Whats New
Years of R&D at Fractal Audio Systems have yielded our next-generation product, the Axe-Fx II. With twice the
power of our former flagship the Ultra, the Axe-Fx II unveils new state-of-the-art algorithms and an innovative
array of great hardware and software features and improvements. This all-in-one preamp/effects processor
stunningly recreates complete signal chainsstompboxes, amps, cabs, mics, studio effects, and morewith
unprecedented power, flexibility, and control. The Axe-Fx II takes "real amp tone and feel" to the next level,
offering the latest word on restoring digital to its rightful place as the superior solution for guitar processing.
Twice the Processing Power
Our philosophy is never to cut corners on processing power. Our new state-of-the-art algorithms required a
powerful platform on which to operate, so the Axe-Fx II features two 600 MHz dual-core Analog Devices
TigerSHARC Digital Signal Processors working in tandem. One is devoted solely to amp modeling while the other
handles effects and system tasks. Mated to the processors is double the RAM of previous Axe-Fx products. The
Axe-Fx II is by far the most powerful instrument processor ever created, with more raw, real-time audio processing
horsepower than anything available at any price. Yet, unlike power-hungry PCs, it consumes less than 40W.
G2 Amp Modeling with Virtual Vacuum Tube Technology and MIMIC
All this power would be useless without superior algorithms to take advantage of it. Years of research have yielded
our G2 Amp Modeling Technology, comprising major breakthroughs in both preamp and power amp modeling.
First, we created our new Virtual Vacuum Tube technology, or VVT. VVT is a complete departure from the static
waveshaping technology used by other products. It is a digital replica of a vacuum tube, complete with time,
frequency, and level dependencies. This creates a level of dynamic realism in a class of its own.
Next, we rewrote the book on power amp modeling. G2 models the entire power amp, including the phase
inverter, power tubes, output transformer, power transformer, choke, filter caps, and more. The results are
amazing: tight bass, powerful midrange, silky highs, plus highly expressive touch sensitivity.
Our amp models are the result of thousands of hours of incredibly detailed analysis of the actual amps that
inspired them. We spent a small fortune searching out and purchasing vintage and modern amplifiers to add to our
reference collection. Multi-point Iterative Matching and Impedance Correction (MIMIC) technology is a
significant advancement in amplifier simulation unmatched by any other product at any price point.
Improved Speaker Simulation, On-board IR Capture and UltraRes
The Axe-Fx II cabinet simulator supports both High-Res (2048) and UltraRes formats, with 150+* factory Impulse
Responses (IRs) including creations by Fractal Audio Systems, RedWirez, OwnHammer, Kalthallen, Jay Mitchell,
James Santiago, TheAmpFactory, and John Petrucci of Dream Theater plus 512* "USER CAB" memory locations
and built-in tools to create your own Axe-Fx II User Cab IRs from a real speaker cab. UltraRes is a proprietary
technique that enhances the spectral resolution of an IR without adding CPU burden or storage requirements.
Tone Matching to Clone any Tone
The Axe-Fx II features a Tone Matching block with the capability to match the sound of a real or recorded amp. It
does this by analyzing the difference between the sound of your preset (the local signal) and a reference
(usually the signal from one or more mics/preamps on a real amp, or a high quality recording.) Tone matching
eliminates guesswork to create exact clones of your favorite tone. A separate Tone Match Mini-manual is
provided.
*The Axe-Fx II Mark 2 has only 130+ factory IRs and 100 user IR slots.

INTRODUCTION
1 Introduction
1.1 What is the Axe FX II?
The Axe-Fx II is an advanced digital preamp and effects processor for guitar, bass, and other musical instruments. It
replaces amps, speakers, microphones, stompboxes, studio processors, and more. It is an all-in-one, end-to-end
great tone solution in a single black box.
Inside, a virtual environment allows you to build your dream rig (hundreds of them, in fact). Choose from an
inventory of hundreds of classic and innovative components. Select and arrange things any way you like, limited
only by the units ample CPU resources and your imagination. Dial in your signature sound using basic controls,
or go deeper with advanced parameters, then save presets for instant recall when playing, performing, or
recording.
The sound is of uncompromising quality, due both to extremely high standards of hardware design and to our
advanced proprietary software algorithms. The Axe-Fx II, like its predecessors, asserts that digital has reclaimed its
birthright as the superior solution for musical instrument processing. Words fall short. You only need to plug in and
play to realize that this is the real deal.
A Word on Modeling
You may have noticed that the Axe-Fx II is not typically described as a modeler. This is not to diminish its debt to
heritage; on the contrary, weve done thousands of hours of deep analysis of the greatest amps, cabs, and effects
of all time. In fact, amps and pedals, their vacuum tubes and other components, plus speaker cabs and many
effects, are painstakingly replicated to perform exactly like the originals. But while the unit includes emulations
based on specific product types, it goes well beyond simply presenting modelswith their limited controls,
features, and soundsto offer a do-it-yourself modeling platform. If its models you want, we can give them to
you, but why stop there?
The Axe-Fx II removes limits instead of recreating them. Take our Wahwah effect, for example. You might just plug
in and start cryin, or you could tune the pedal sweep, tweak the resonance, overdrive the circuit, and tailor the
sound to your exact wishes. Try the Plexi. Dial it in just right. Then open things up and hear what happens when
you drop in the tonestack from a modern Rectifier (all it takes is one turn of a knob to make the change). There are
hundreds more ways that the sound can be customized. Rediscover your all-time favorites, or go crazy creating
sounds you only wished someone would put in a product. And you dont need to be an engineer to do so, as the
unit is extremely user-friendly.
You are not alone in the quest for tone, either. The Fractal Audio online community has amassed a wealth of
knowledge and is ready to share expertise on every subject, from the deviling details of differently dated diodes in
dilapidated distortions to how to set up your favorite artists exact gear used in the exact order with the exact
settings for the first half of the second bridge of the third bonus track off the re-master.
In comparison to its predecessors, the Axe-Fx II has some great new capabilities as an effects modeler. Just as our
previous products allowed you to select, for instance, a TYPE of Amp, Cab, or Drive, now the Chorus, Delay,
Flanger, Phaser and other effects include a control to automatically dial in all-time favoritessettings like
Doc v15.0b
INTRODUCTION
dimension chorus, tape delay, analog flanger, script 90 phaser, and many more. Once you make a
selection, however, you can go beyond the model. With deep recreations of the intricacies and interactions behind
great tone, we create not only a sample or profile but a multidimensional whole enchilada. Again, just plug in and
hear it for yourself.
To re-pose the original question then, what is the Axe-Fx II?
The Axe-Fx II is the new flagship processor from Fractal Audio, with far more power and many more capabilities
than the former heavyweight champion, Axe-Fx Ultratwice the DSP in fact, allowing it to deliver far more
detailed amp modeling, plus numerous other upgrades. It contains our best-ever guitar amplifier simulation and
effect technologystate-of-the-art algorithms designed to sound and feel like the real thing. It is a fully routable,
fully programmable, real-time controllable, multi-effects processor offering the utmost in sound quality, with
unrivaled flexibility and control options. It is a modeling platform upon which you can create any number of
incredible guitar tonesable to replace entire rigs of traditional gear with a single black box. Lets take some of
these concepts a bit further:
Routable: Place effects freely in any order and layoutseries, parallel, or complex networks, including feedback
loops and external send and return, at any point in the signal chain.
Programmable: Every effect has a full complement of parameters offering desirable features and tremendous
range. Gone are the limits of processors with restrictive options or little-to-no depth.
Controllable: Many parametersincluding all the usual expression pedal suspects and every effect bypass
switchcan be operated remotely via MIDI, offering great real-time performance control capabilities. You can map
control curves, assign multiple parameters at once, tap powerful global controllers, and much more.
Multi-Fx: The Axe-Fx II offers all the classic effects plus a few new ones. The massive effects inventory allows any
preset to use two or more of almost every effect block type, so you can build huge virtual rigs. In addition, many
effects now include X/Y states so you can instantly swap one set of settings for another without changing presets.
Almost all the effects in the Axe-Fx II process in full stereo.
Utmost Quality: Sound quality is our first-and-foremost criterion for the success of the Axe-Fx II. This shows in the
hardware design and in every detail of our proprietary natural processing software algorithms. Many of these
replicate patterns that occur in nature (thus our company name of Fractal Audio Systems). The amp simulations
use unique, dynamic, non-linearity generators that produce smooth, even-ordered harmonics, giving a depth to
the sound that other processors lack. Our effects have been vetted and championed by some of the worlds most
demanding and discriminating players.
Rig Replacer: Having everything in one box has some great advantages, especially when that box is as powerful
and versatile as the Axe-Fx II. In addition to being able to replace big rigs outright, this tightly integrated, unified
system offers certain fringe benefits. No longer does changing a drive pedal mean fighting with cables half-an-inch
too short. No longer must you labor over deciding which amps your tours budget will or wont allow you to ship or
handle. Gone are the headaches and hassles of systems of so many boxes strung together with so many wires,
prone as they are to failure and noise. And lets say a small meteor hits the stage and obliterates your Axe-Fx II:
you can literally restore to a new unit during the intermission and be up and running again for the next set.
Finally, after youve replaced your entire rig, the Axe-Fx II lets you continually re-invent it without ever touching
Velcro, rack screws, or your credit card.
Doc v15.0b
INTRODUCTION
The figure above presents a stylized example of an Axe-Fx II preset. The INPUT is routed through a SHUNT to feed a
WAH block. (The shunt has no effect on the sound and is shown only to introduce the concept of its use.) The
WAH block is connected to an AMP block (we might set its type to Plexi Normal), which in turn feeds a CAB
(one of the many 4x12 options, perhaps). This is routed to a reverb (REV) and then to the OUTPUT.
The size of a preset is limited only by the grid structure, block inventory, and total processing power or CPU.
Youll be pleased to discover that there is enough CPU power to allow large and complex creations.
Doc v15.0b

This includes both S/PDIF and AES/EBU format Input and Output Jacks. Only one or the
other pair of jacks can be active at any time depending on the setting of the SPDIF/AES SELECT parameter
in the I/O:AUDIO menu (p. 134). These jacks transmit and receive at a fixed rate of 48k.
21.
This provides the means to connect the Axe-Fx II to a PC or Mac, enabling a host of two-way audio
and MIDI capabilities. See section 2.3 on p.12. Like the digital i/o, USB Audio operates only at 48k.
22.
jacks The Axe-Fx II XL has separate dedicated MIDI IN, MIDI OUT and MIDI THRU jacks.
Unlike a shared/soft MIDI THRU, the XLs dedicated MIDI THRU jack adds no latency, but it is "hard-wired"
to the MIDI IN PORT, and therefore does not pass signals from other MIDI inputs. For THRU functionality
when using an MFC-101 at the FASLINK or MFC port of an Axe-Fx II XL, MIDI OUT can be made to work
as a soft THRU by setting MFC ECHO TO MIDI OUT to "ON" (on the MIDI page of the I/O menu).
The Axe-Fx II Mark II has a MIDI Out/Thru combo jack that transmits or forwards MIDI signals to another
device. MIDI THRU is disabled by default but can be enabled on the MIDI page of the I/O menu).
23.
Jack When using the MFC-101 MIDI Foot Controller over a 7-pin MIDI cable,
connect the supplied AC Adapter to this jack to provide power to the floor unit via pins 6+7. Some other
MIDI controllers also support the use of phantom power on pins 6+7.
WARNING! Do not connect an AC adapter with a rating higher than 1A to the Phantom Power jack. Doing
so will damage your Axe-Fx II.
24.
Control Port This RJ45 jack allows you to use a standard (non-crossover) CAT5/Ethernet cable to
connect the Axe-Fx II to a Fractal Audio Systems MFC-101 MIDI Foot Controller. The cable used to connect
the Axe-Fx II and MFC-101 carries two-way data communication and phantom power without needing an
external wall wart adapter. High quality Ethernet/EtherCON cables are available via
http://www.fractalaudio.com/cables. (Axe-Fx II Original Version supports only Ethernet, not EtherCON.)
WARNING! DO NOT connect the MFC jack to an Ethernet device such as a computer, hub, switch, or
router, as damage to one or both units could occur! Damage of this type leaves tell-tale signs on the
motherboard and is NOT covered under warranty.
Always ensure that the Axe-Fx II power is OFF before inserting/removing Ethernet/EtherCON cables.
Be careful not to insert other types of connectors such as USB or guitar cables into the MFC port of the
Axe-Fx II, as doing so can damage your unit, leaving tell-tale damage NOT covered under warranty.
The
connector of the Axe-Fx II XL allows you to connect to the FASLINK port of an MFC-101
Mark III. The standard XLR cable used for a FASLINK connection powers the MFC without an external
wall wart adapter, and carries 2-way communications. An optional XA-2 FASLINK Adapter allows you
to connect the Axe-Fx II XL to an earlier MFC-101.
The optional XA-1 FASLINK adapter adds a FASLINK port to the Axe-Fx II Mark II.
Find FASLINK adapters at http://shop.fractalaudio.com
25.
Jack This jack is used to connect an external expression pedal or switch to control various
functions of the Axe-Fx II. See p. 16 for more information on this function.

up to four channels from the Axe-Fx II to the computer, and two-way MIDI-over-USB. All features can be used
simultaneously. Note that even though the Axe-Fx II is fully class-compliant, you must still install the drivers found
at http://fractalaudio.com/support .
Audio and MIDI ports (shown in the top dotted-outline boxes above) have different names on different systems. In
many applications, you can also assign friendly names to audio and MIDI ports.
Two Simultaneous Channels of 48k/24-bit Audio from the Computer to the Axe-Fx II
Two output channels allow audio to be sent from the computer to the Axe-Fx II where it can be processed by the
unit or simply played back to OUTPUT 1.
To process computer audio with the onboard effects, set the MAIN INPUT SELECT (p. 134) to USB. Computer
audio will be routed to the grid INPUT. This allows you to re-amp a dry track, for example, or use the Axe-Fx II to
process other audio or plugin tracks. It is possible to simultaneously record the processed output on the computer
using the Axe-Fx II audio inputs (0/1).
To pass unprocessed computer audio through the Axe-Fx II, set the MAIN INPUT SELECT (p. 134) to ANALOG
(IN1) (the default setting) or SPDIF/AES. Computer audio is mixed with the regular output of the Axe-Fx,
allowing you to play along with backing tracks or use the Axe-Fx II as a high quality soundcard.

OVERVIEW
Four Simultaneous Channels of 48k/24-bit Audio from the Axe-Fx II to the Computer
Four outputs, typically numbered 14, allow audio to be routed from the Axe-Fx II to the computer and recorded,
processed, or monitored.
USB/DIGI OUT SOURCE in the I/O:AUDIO menu (p. 134) determines what is sent to the first pair of USB outputs:
Selecting OUTPUT 1 L+R sends the Axe-Fx II main output to the computer. The same signal is, of
course, still routed normally to the rear XLR and unbalanced jacks. Use this to record your fullyprocessed guitar.
Selecting OUTPUT 2 L+R routes output 2typically the FX loop block (p. 66) to the first two outs.
Selecting MAIN INPUT routes the main input (see MAIN INPUT SELECT p. 134) to the first two outs.
A similar result can be obtained by using OUTPUT 1 with a shunts-only preset (p. 29).
Remember to turn off the Input Noise Gate and set Output levels to 0.0
Switching INPUT 1 LEFT SELECT (p. 134) to REAR allows you to record the line level outputs of a
microphone preamp, keyboard, or any other sound source via the rear INPUT 1 L/R jacks.
The second pair of USB Outputs always outputs the raw, dry, unprocessed signal from the main input (i.e. the front
jack or the rear
jack, depending on both what is selected under INPUT 1 LEFT SELECT (p.
134)) and the rear
jack). These require USB 2.0 support (see Minimum Requirements above).
Warning: As with all input/output systems, certain routing configurations can result in audio feedback loops. Please exercise
care not to route active outputs to active inputs, or damage could occur to connected amps, speakers, or your hearing.

simply too hot. Reduce the output of one or more blocks (the AMP block OUTPUT LEVEL is usually a good starting
point) or adjust the main GAIN slider of the presets output mixer (see p. 115).
When you need to adjust the level of all of your presets at once because some are clipping, you can also use the
GAIN slider on the OUT1 or OUT2 graphic equalizers to make a global adjustment. (p. 133)
Clipping can also be caused if you have increased the BOOST/PAD setting for one of the converters and can be
reduced if you adjust this setting to be closer to 0 dB (see p. 134). Block or preset adjustment may still be required.

Connect an expression pedal or footswitch to the pedal jack to control sound functions. You must first configure
the TYPE, and perform a simple calibration routine when using an expression pedal. See section 9.5 on p.140 for
how to use the PEDAL page of the I/O menu.
Any type of external switch can be used, as long as its contacts make and break the connection between tip and
sleeve on a regular 1/4 guitar cable. Expression pedals should have a linear resistance taper and max resistance
between 10k and 100k, and must be used with Tip-Ring-Sleeve cables.
To control sound parameters, you must first assign the PEDAL jack to an EXTERNAL CONTROLLER and then set up
a MODIFIER. This topic is covered in section 7: Modifiers & Controllers on p. 123, with a section specifically
about External Controllers on p. 131.

Notes: With its built-in amp and speaker simulations, the Axe-Fx II can be played directly into P.A. or other selfamplified, full-range, flat-response (FRFR) speakers. Externally amplified (passive) FRFR speakers are equally wellsuited. This might just as easily be a Front-of-House system with floor or in-ear monitors. In this configuration, the
Axe-Fx II creates all aspects of the end-to-end guitar chain for the ultimate in tonal flexibilitystompboxes, amps,
cabs, post effects, and more. Optional headphones provide an alternate way to listen when cabs are not present or
are switched off. Balanced (XLR) or unbalanced (1/4) jacks and cables can be used to connect the Axe-Fx II, with the
former providing the advantage that less noise will be picked up over longer cable runs. If only one speaker is used,
set OUT 1 MODE in the I/O menu (p.134) to one of the mono options.

Global Settings: Power Amp Simulation ON or OFF (see below), Speaker Cabinet Simulation OFF
I/O Settings: Set OUT1 MODE (p.134) as required for stereo or mono.
Notes: Depending on the character of the amplifier being used, Power Amp Simulations may need to be ON or OFF
for this type configuration.
Power Amp simulations should be turned ON when using a neutral-sounding (Solid State) power amp that
does NOT significantly affect the tone or feel.
Power Amp simulations should be turned OFF when using the RETURN on a tube head or combo, or a guitaroriented tube power ampone that significantly affects to the tone and feel.
In either case, it is completely safe and reasonable to try both settings to see which you prefer.
Whenever you use the Axe-Fx II with traditional guitar speaker cabinets (whether open back or closed, small or
large, alone or in pairs) it is best to turn Speaker simulations OFF in the CONFIG page of the GLOBAL menu (p. 132).
Guitar speakers differ from full-range speakers in that they are voiced to focus on traditional electric guitar sounds:
mids tend to be prominent, highs rolled off, etc.
The settings required for this type of operation are not ideally suited for monitoring through the Axe-Fx II
headphone jack, as what you hear through headphones will not sound like what you will hear through the speakers.
Switching Power Amp and Speaker Sims on and off, however, is simple and can be done as needed to switch back
and forth.

Global Settings: Defaults OK, since typical 4CM presets will not have AMP or CAB blocks!
I/O Settings: Set INPUT and OUTPUT MODES as required for stereo or mono (Remember: even in a stereo rig, when
you are connecting a guitar to the front INSTRUMENT input of the Axe-Fx II, INPUT 1 MODE must be set to LEFT.)
Adjust the two OUTPUT BOOST PAD parameters to lower the noise floor. See p.134 for details on these parameters.
Notes: This highly integrated setup places the Axe-Fx II simultaneously in front of an amplifiers preamp section,
where it replaces traditional stompboxes, and in its effects loop, where post effects like delay and reverb have a
totally different sound than when used out front. (Although a head and separate cab are shown, many combo
amps also offer an onboard effects loop and can be used as well.)
To use the 4CM, you will need to create special presets where AMP and CAB blocks are replaced by the FX LOOP
block (p. 66). Signal hits the Axe-Fx II first, into any effects that you want in front of the ampcompressor, drive,
wah, and the like. Then, the FX LOOP block is used to insert the preamp of the actual amplifier on the grid. Output
2 of the Axe-Fx II has an all-new, extremely low-noise design that is well suited for feeding the front of an amplifier.
The signal makes a round trip to the amps preamp and back to the grid, where it is then processed by additional
blocksyour post FX: maybe chorus, delay, reverb, etc. The final routing is via Axe-Fx II OUT1/L to the Return
(Power Amp Input) of the amplifier which powers your speaker. To extend this configuration for optional stereo,
connect OUT1/R to the RETURN of a second amplifier, bypassing that units preamp altogether.
The new Boost/Pad functions are designed to help run the OUT1 and OUT 2 D/A converters at optimum levels,
padding their outputs for even lower noise. To find the right setting, adjust either of these controls upwards until
you light the respective OUT CLIP LED on the front panel, then back off a few dB to prevent further clipping. Youll
actually hear the noise floor drop as you make these adjustments.
Humbuster technology (p. 167), featured on all 1/4" outputs of the Axe-Fx II, can also provide a significant
reduction of ground hum when simple stereo-to-mono cables are used to connect to an amp or other device.
The no-amp/no-cab presets required for this setup are not well suited for headphone monitoring, as what you hear
in the headphones will not include any power amp or speaker simulations.
Note: If your amps effects loop is the PARALLEL type, the chain of post-FX-loop blocks must be set to output a wet-only signal.

CONNECTIONS
Global Settings: Default I/O Settings: Set OUT1 MODE and OUT 2 MODE as required for stereo or mono
Notes: This setup is similar to others in which the Axe-Fx II is used direct into full-range speakers. Here, however, a
special preset feeds both the direct and power amp/cab rig by placing an FX LOOP block between the AMP and CAB,
so signal is passed to Output 2 before it is processed by the CAB block and passed to Output 1.
Note: A template is provided in preset memory location 381: OUT1->FOH OUT2->CAB
Another possibility is to use a preset with two totally separate signal paths. In the example below, the top (direct)
signal path contains a fully simulated guitar chain, while the second (backline) does not use a CAB sim.
The backline chain differs from the direct chain in several key ways. First, its AMP block has the SAG parameter set
to 0.00 to disable power amp simulation in that block only. Since real guitar speakers and a power amp are being
used at Output 2, no CAB block is inserted. Duplicates of effects following the amp are placed. This is useful because
different settings may be required to sweeten each system. The backline chain ends in an FX LOOP block, which is
routed via OUTPUT 2 to a power amp. If a very neutral amp is used, the SAG of that second AMP block might be
set higher for simulated tube power amp tone and dynamics.

Global Settings: Defaults OK, since special presets required should not have AMP or CAB blocks!
I/O Settings: Change INPUT 1 LEFT SELECT to REAR if using the Axe-Fx II in an effects loop as shown above, left.
Leave the default setting of FRONT if you are connecting a guitar to the Axe-Fx II, as shown above, right.
Notes: Although it was designed for complete guitar signal path simulation, the Axe-Fx II can also be put to superb
use as a standalone FX processor. As such, it can be placed between guitar and amp to replace stompboxes or in an
amps effects loop where a rack processor would normally appear.
To use either setup, you will need to create custom presets without AMP or CAB blocks. For operation inside an
amps effects loop, use the REAR input(s) and set INPUT 1 LEFT SELECT (section 9.2) accordingly. Presets in this case
will likely contain only those effects that sound best after a preamp: chorus, EQs, delays, reverbs, certain types of
pitch shift and modulation, et al.
For the best-case scenario when running in front of an amp, recognize that Output 2 of the Axe-Fx II has an all-new,
extremely low-noise design that is well suited for this purpose. Effects-only presets should terminate in an FX LOOP
block to route signal to OUTPUT2. (In this case, nothing would be connected to the FX RETURN of the Axe-Fx II.)
The new Boost/Pad functions are designed to help run the OUT1 and OUT 2 D/A converters at optimum levels,
padding their outputs for even lower noise. To find the right setting, adjust either of these controls upwards until
you light the respective OUT CLIP LED on the front panel, then back off a few dB to prevent further clipping. Youll
actually hear the noise floor drop as you make this adjustment. Humbuster technology (p. 167), featured on all
1/4" outputs of the Axe-Fx II, can also significantly reduce ground hum when simple stereo-to-mono cables are used
to connect to an amp or other device.
It is easy enough to extend each of the above configurations for use in stereo. With the Axe-Fx II in a loop, connect
OUT1 R to the RETURN of a second amp, bypassing that units preamp altogether, or run fully within the loops of
two separate amps using IN1 L/R and OUT1 L/R. With the Axe-Fx II between guitar and amp, connect a second
amplifier to OUT2 R. The no-amp/no-cab presets required for the scenarios in this section are not well suited for
headphone monitoring.

EXAMPLE 3: Dual Amp Preset This preset shows a dual-amp rig. A series of effects (Wahwah, Drive, Phaser)
begins the chain, then the signal is split into two amps and two cabs. Signal is panned hard left and right with CAB
block BALANCE controls and then merged to feed stereo post effects. A Multiband Compressor helps balance
dynamics, while spaces in the chain leave plenty of room for future expansion.
EXAMPLE 4: Complex Routing The program below demonstrates a more intricate routing scenario. The signal is
split and merged at various points between the input and the output, with various effects appearing before and
after two independent amps. Notice the complex feedback-loop routing in parallel with the dry signal feeding
the amps, and the reverb at the end of the chain running in parallel. (Reverb level is controlled by an envelope for
a ducking effect).

INPUT DRIVE (aka Drive) sets the amount of preamp gain/distortion. Used in conjunction with the
MASTER (see below), INPUT DRIVE determines whether the sound will be clean, slightly broken up, moderately
OVERDRIVE The OVERDRIVE control appears only for certain amp types. Note that DRIVE and OVERDRIVE
are applied to the appropriate points in the circuit for the amp being modeled, i.e. prior to the last triode
stage or prior to the third triode.
INPUT TRIM Amps without OVERDRIVE will display the INPUT TRIM instead. This allows you to adjust for
more or less preamp gain than the actual circuit being modeled. This is different than the Input DRIVE control
because DRIVE interacts with the surrounding circuitry, changing frequency response as it is varied.
BOOST Toggles an additional 12 dB of gain at the input of the amp sim. (For amp types that have an
OVERDRIVE control (see above,) BOOST appears only on the ADVANCED page.)
BASS, MID, TREBLE While other modelers use simple filters to approximate amp tone controls, the AxeFx II replicates exactly the frequency and phase response of a classic passive tonestack. In most instances,
matching knob settings between the Axe-Fx and the original amp will recreate the same tones.
Some of the original amps simulated on the Axe-Fx II do not have all of the tone controls offered on our
models. Some, for example, have no mid control. To faithfully simulate the configuration of the original, set
any superfluous controls to noon (or 0.00 if you are using the ACTIVE tonestack type; see below). Of
course, you may still adjust to achieve tones the original amp does not have.
Extreme tone and high gain settings can cause pickup squealing or excessive noise. This is especially true
with the TONESTACK TYPE (p. 54) set to ACTIVE.
BRIGHT This is a high treble filter between the preamp and power amp, useful to darken or brighten the
tone in a unique way. This control accurately replicates the Presence control on the original version of the
USA Pre type amps. (Not to be confused with the BRIGHT SWITCH (see below) which engages/disengages a
capacitor across the drive pot.

Doc v15.0b
EFFECTS GUIDE
BRIGHT SWITCH Many amplifiers contain a treble peaker, included as a pull or toggle switch, or even
hard-wired. Every amp TYPE on the Axe-Fx II includes this control (even if the original mode does not). The
effect may be subtle or quite pronounced depending on the amp TYPE. This is also affected by the BRIGHT CAP
setting (p.54). If the original amp had no bright circuit, BRIGHT is OFF by default but can still be turned on to
apply circuit values suited to an amp of that general type. If the amp has a hard-wired treble peaker, the
default BRIGHT state is ON. To turn the bright switch ON or OFF, use the
keys to select the TREBLE knob
and press ENTER. The BRT switch beneath the knob will fill to indicate that the circuit is engaged.
BRIGHT switch ON
CUT SWITCH (engaged by a switch beneath BASS) reduces the amount of low frequencies into the amp
simulation. This can be used to achieve a tighter tone or to reduce low-end flub.
FAT SWITCH In the same way the TREBLE knob (above) also controls BRIGHT, the MID operates as a Fat
switch, emphasizing midrange body by shifting the tonestack center frequency down.
SAT SWITCH The Saturation Switch engages a popular mod between the preamp and the tonestack for a
thicker, more aggressive distortion character. ON and IDEAL settings differ only in their effect on the
output level. (IDEAL gives you the higher output level you wish a real amp had with saturation engaged ;-)
PRESENCE/HI-CUT Boosts (or cuts) the upper frequencies from the power amp simulator by varying the
negative feedback frequency response. Increased presence can help a sound cut through a heavy mix.
Amps with no negative feedback circuits in their design cannot utilize a presence circuit. If NEGATIVE FDBK is
set to 0.00, PRESENCE becomes a negative high-shelf equalizer at the output of the power amp, and its label
changes to HI-CUT. This allows you to control the high-frequency response of the power amp for models
that dont have any negative feedback. When changing to a model with no negative feedback (i.e. Class-A,
Mr.Z, Recto Red), be sure to check your presence settings as settings higher than zero might darken the sound
undesirably.
DEPTH Boosts low frequencies from the power amp simulation by varying the negative feedback frequency
response. The DEPTH control is set by default to an appropriate value when the amp TYPE is selected, but this
setting may be overridden.
TUBE TYPE The virtual power amp in the Axe-Fx includes modeling of the plate impedance of the power
tubes. Plate characteristics are adjustable via DYNAMIC DAMPING, an advanced parameter. The TUBE TYPE
parameter sets DYNAMIC DAMPING automatically for you, allowing you to select from common power tube
types instead of selecting a number. EL34, EL84, 6L6, 6V6, KT66, KT88, 6550, 6973, 6AQ5 and 300B (triode) are
offered, as well as an ideal tetrode and ideal pentode. The power tube type defaults to the appropriate type
when the amp type is selected but may be changed freely.

EFFECTS GUIDE
NEG FDBK This controls the amount of negative feedback, or damping, in the power amp simulation.
Higher values give a tighter and brighter sound but can sound harsh at very high master volume levels. Lower
values give a loose and gritty sound and feel. Like many other power amp parameters, NEGATIVE FEEDBACK is
set to an appropriate value whenever you change the amp TYPE, but it can then be changed as desired. For
example, you might dial in some negative feedback on a Top Boost to give the power amp a more
American sound while still retaining the preamp voicing.
MASTER VOLUME The almighty Master Volume is a very important control. It determines the distortion
and dynamics characteristics of the power amp simulator, and its setting is key to an amps sound. As the
Master is turned up, the entire character of the amp will change. The tone controls will have less influence on
the sound, and the sound will have more bloom and touch sensitivity. Settings for MASTER dont necessarily
correspond to knob positions on the amp being modeled. With a little experimentation on your favorite AxeFx II amps, you will learn to appreciate the qualities of different DRIVE and MASTER VOLUME settings and how
to find the great tones offered by different combinations.
When you select an amp TYPE, the MASTER will change to an appropriate/typical setting for that amp. If a
real amp doesnt have a Master, the correct setting for MASTER VOLUME is 10.0.
At high Master settings, less drive is usually required, especially for high-gain types.
Amps designed for preamp distortion will typically sound great with the MASTER VOLUME set low to
prevent the tone becoming muddy or noisy. This includes the USA Lead types, SOLO 100, and others.
Amps with negative feedback (damping greater than zero) tend to have a crunchier power amp
distortion, which can get raspy if driven too hard. You can experiment with the interactivity of DAMPING
(see Advanced Parameters, below) and MASTER VOLUME to achieve desired distortion timbres.
Setting SAG (see below) to zero will disable Power Amp simulation, at which point the MASTER becomes a
simple level control with 40 dB of range.
If more power amp gain is desired, the MASTER VOLUME TRIM parameter (See section 5.1.4) can be used
for increased range.
OUTPUT LEVEL This is a copy of the LEVEL control on the MIX page for easy volume adjustment without
page turning. This only affects volume. It has no effect on tone! For many people, this is the go to parameter
for setting the output level of a preset.
Amp EQ Page
The amp block includes a built-in graphic equalizer, eliminating the need to use a separate block for tone-shaping.
You can change the number of bands to a variety of types. Press
to reset all EQ bands to flat. See Graphic
Equalizer [GEQ] on (p.73) for additional detail on bands, Q, etc.
LOW FREQ, LOW Q, LOW RES Guitar loudspeakers have a low-frequency resonance, typically about
100 Hz. This shifts up slightly when the speaker is mounted in an enclosure. This resonance causes an increase
in the power amplifier response due to the finite output impedance of the power amp.
42
Doc v15.0b
EFFECTS GUIDE
HI FREQ, HI RES A loudspeaker voice-coil presents an inductive load to the power amp at high
frequencies. This inductive load, in conjunction with the output transformer capacitance, creates a highfrequency resonance at the specified frequency.
XFRMR DRIVE Controls how hard the virtual output transformer is driven. Higher values simulate a
smaller, more easily saturated transformer.
CF COMP Controls the amount of cathode follower compression. This will default to zero (no compression)
for amp types that do not have a cathode follower in the original circuit, but can be set anywhere on any
model. This same parameter is shown in the Advanced Parameters page as CATHODE THRESH.
CATHODE SQUISH The Axe-Fx II has cathode squish modeling for cathode biased power amp models.
CATHODE SQUISH sets the amount of bias shift due to cathode voltage rise. This parameter is set to a suitable
value upon selecting of an amp TYPE. (Setting CATHODE SQUISH to zero defeats the cathode squish modeling.)
PICK ATTACK This parameter controls a sophisticated dynamic range processor that operates on leading
edge transients. Negative values reduce pick attack while positive values enhance it.
OUT COMP This parameter controls a compressor specifically tailored to reducing the output dynamic
range of the Amp block. Note that this compressor runs in the master DSP and if set to a non-zero value will
increase CPU usage. The Out Comp parameter controls the amount of compression (compression ratio). In the
Advanced menu the user can also adjust the compression threshold via the advanced Comp Thrshld
parameter, if desired. The bar graph at the bottom of the menu displays the amount of gain reduction.
XFRMR MATCH Transformer Match is an extremely powerful parameter that sets the relative output
transformer primary impedance to determine how easily the power tubes are driven into clipping. Higher
MASTER Volume settings result in a more pronounced effect. Increasing XFRMR MATCH causes power tubes to
clip sooner. Decreasing XFRMR MATCH causes power tubes to clip later and therefore the phase inverter and
grid clipping becomes more predominant. At higher settings, the resonance settings on the SPEAKER page of
the AMP block will be more pronounced. For optimum results bring up the MASTER until the desired amount
Doc v15.0b

EFFECTS GUIDE
of power amp distortion is achieved, then adjust matching until the character of the distortion is as desired.
The various LF and HF resonance parameters interact strongly with this parameter so be sure to experiment
with those as well when crafting a tone.
MODELING MODE Formerly Grid Modeling, this parameter has been renamed and repurposed. It
offers the following choices:
Authentic Replicates a tube amplifier with the utmost accuracy.
Smooth Sets Triode Hardness to minimum, essentially creating an ideal preampand turns off grid
conduction in the power amp. This removes some of the nasty distortion that tube amps create.
Ideal Removes most of the warts from the modeling which includes grid conduction, output
transformer distortion, bias shifting and AC power supply modeling. Supply sag, screen voltage
effects and crossover distortion are still modeled.
Ideal/Smooth Combines the ideal and smooth options.
MSTR VOL TRIM Allows you to adjust the range of the MASTER. Increasing the value above 1.0 will cause
more gain in the virtual power amp and vice versa.
BRIGHT, SAT These appear on the PRE page, but are offered here with modifier attachment options.
LOW-CUT FREQ This control allows you to reduce the amount of low-frequency content at the input to
the amp simulator. This parameter defaults to a value for each type but can be overridden if desired.
HIGH-CUT FREQ This control sets the cutoff frequency of a low-pass filter at the very end of the preamp
simulation. It defaults to a preset value for each amp type but can be overridden if desired. Experiment with
this to fine-tune your tone. For example, some of the higher-gain amp types are characterized by fairly heavy
filtering after the preamp stage. Increase or decrease for a brighter or darker tone.
DYN PRESENCE increases or decreases highs when the virtual power amp is pushed.
DYN DEPTH Uses the low-frequency speaker information from the SPEAKER page to set inversehomomorphic filters resulting in a very musical low-end control. Dynamic depth is not present on real amps,
but provides a valuable tone-shaping tool on the Axe-Fx.
Note: DYNAMIC PRESENCE, DYNAMIC DEPTH and CHARACTER (see below) are powerful. A little goes a long way.
DYNAMIC DAMPING The Axe-Fx virtual power amp models the plate impedance of the power tubes.
They give tight bass and warm highs at higher MASTER settings, with 3-dimensional tone. The plate

characteristics are adjustable via the Dynamic Damping parameter. The value of this control is changed when
you set the TUBE TYPE parameter on the PWR page.
DEFINITION This control is a basic tilt EQ which adds highs/cuts lows, or vice versa. It is located at the
amp input, so its effect is heard before preamp distortion or a front-end tone stack.
CHARACTER, CHARACTER FREQ These two parameters control a powerful inverse homomorphic filter
which adjusts tone dynamically in a very musical way. CHARACTER FREQUENCY sets the center frequency of the
filter while CHARACTER sets how pronounced the effect is. To darken the tone when playing harder, one might
set the frequency to 10000 Hz and the amount to a negative value. A positive setting would have the reverse
effect of brightening the amp when pushed. CHARACTER defaults to zero when amp type is changed.
BRIGHT CAP Sets the value of a virtual capacitor to determine the sonic effect of the BRIGHT switch
(above). Increasing this will make the preamp brighter and vice versa.
MV CAP This sets the value of the bright cap across the Master Volume pot
TONESTACK TYPE The BASS, MID and TREBLE controls operate by default as passive controls. That is,
they simulate exactly the frequency and phase response of the classic passive tonestacks found in the original
amplifiers our simulations are based on. The TONESTACK TYPE control lets you change this behavior from
PASSIVE to ACTIVE, or to substitute the passive tonestack of another amp type.
Selecting the ACTIVE type gives each tone control +/- 12 dB boost/cut operation for up to twice the
range of a typical amplifier. Since the active tone controls are more sensitive, small adjustments have
bigger effects, and less extreme settings still achieve pretty extreme sounds. For example, full PASSIVE
treble for a high-gain British amp would be equivalent to only +5.0 dB ACTIVE, leaving 7 dB of additional
headroom! Active tone controls do not interact like those of a typical amplifier, so when you adjust the
treble, the mid and bass are not affected. This can make dialing in a certain tone easier and quicker than
it might be with a PASSIVE tonestack.
Selecting a substitute tonestack allows you to mix and match amps and tone stacks to create your own
hybrids. This allows you to use, for example, a Plexi-type tonestack on a Blackface amp model, or a
modern German tonestack in a British Preamp.
TONESTACK FREQ Sets the center frequency of the tone controls to determine their effect on the sound.
This control works whether you are using ACTIVE, PASSIVE, or substitute tone stacks.
This parameter defaults to an appropriate value whenever you change the amp TYPE, but it can then be
changed as desired. However, if you subsequently change the TONESTACK TYPE, the TONESTACK FREQUENCY will
not necessarily be correct anymore.
TONE LOCATION This control lets you change the location of the tone stack. PRE places the tone stack
at the input to the preamp, POST places the stack between the preamp and power amp. MID places it
between the last two triode stages, and END places it after the power amp (which is physically impossible
with a real amp). Defaults to an appropriate value whenever you change the amp TYPE.
EQ TYPE This determines the number of bands for the amp blocks built-in graphic equalizer, and whether
it will be variable Q, constant Q, or passive type.
PRESENCE FREQ This multiplier alters the center frequency of the amps PRESENCE control, which is
naturally determined based on the current selection for amp TYPE.
Doc v15.0b
45
EFFECTS GUIDE
DEPTH FREQ Alters the center frequency of the amps DEPTH and DYN DEPTH controls. This parameter
defaults to an appropriate value whenever you change the amp TYPE, but can then be changed as desired.
POWER TUBE BIAS Sets the bias point of the virtual power amp. Lower values approach pure Class-B
operation. Higher values approach pure Class-A operation.
NEG FEEDBACK This is a duplicate of the same control on the amps POWER page.
POWER SUPPLY TYPE, AC LINE FREQ Selects between AC and DC virtual power supply types. AC
rectification and resulting supply ripple are modeled, and the line frequency is also selectable. Note that high
values of Sag with low B+ Time Constant values can cause ghost notes when the supply type is AC (as in a
real amp). Lower B+ Time Constant values will make the amp feel faster but too low can cause ghost notes.
MAINS IMP. (SAG) This is a duplicate of the SUPPLY SAG parameter on the DYNAMICS page.
Preamp modeling uses screen voltage from power amp in calculations rather than operating independently.
This improves feel as preamp voltage drops with power amp sag. The effect is more noticeable as SAG is
increased. Note that preamp sag has a long time constant and, as such, the initial pick attack is relatively
unaffected while sustained sounds undergo compression. This results in a chewier sensation.
PREAMP SAG Turning this ON replicates the behavior of an integrated tube head or combo amp as
described above. Turning this OFF replicates the preamp sag behavior of separate preamp and power amp.
B+ TIME CONSTANT Controls the rate of change in the power tube plate supply. Lower values give a
bouncier feel, while higher values give a tighter feel.
CATHODE SQUISH, SQUISH TIME The Axe-Fx II has cathode squish modeling for cathode biased
power amp models. CATHODE SQUISH sets the amount of bias shift due to cathode voltage rise and SQUISH
TIME sets the time constant of the cathode network. These parameters are set to default values upon
selection of an amp TYPE. (Setting CATHODE SQUISH to zero defeats the cathode squish modeling.)
OUTPUT COMP, COMP THRESHLD These control the output compressor (detailed previously on the
DYNAMICS page.) The THRESHOLD can only be set here, on the ADVANCED page.
BIAS EXCURSION The Axe-Fx II accurately models grid conduction and resulting bias excursion. This
results in a more dynamic, thicker and bouncier tone. BIAS EXCURSION controls how much the grid voltage
droops when the grids conduct.
TRIODE1 PLATE FREQ, TRIODE2 PLATE FREQ These parameters set the cutoff frequency of the last
two triodes in the chain. Many amps have a capacitor across this triodes plate resistor. This capacitor is used
to smooth the response and reduce noise. You can adjust the amount of capacitance, and the resulting
frequency, using these parameters.
MV LOCATION Sets the location of the Master Volume. Most amps have the Master Volume before the
phase inverter (Pre PI). On some amps (like the AC types) the Master Volume is after the phase inverter
(PI). A third option, pre-triode, is the default for amp types based on Hiwatt models.
AMP VOICING Voices the amp to a variety of tonal styles, taking the guesswork out of mix engineering by
automatically adjusting the overall tone. Choose Neutral for the raw amp sound or choose one of the other
voicings for a quick mix-ready tone.
46
Doc v15.0b
EFFECTS GUIDE
POWER AMP LO CUT, POWER AMP HI CUT These filters are provided for shaping the tonal color of
the virtual power amp. Note that in addition to applying a voicing filter, the POWER AMP VOICING parameter
(Basic Amp Parameters, beginning on p. 40) will also automatically set values for POWER AMP LO and HI CUT.
CATHODE THRESH This is the same as the CF COMP parameter on the DYN page. Determines the amount
of compression in the virtual cathode follower.
CATHODE TIME Works with the CATHODE THRESH and RATIO, setting the attack time of the compressor.
CATHODE RATIO Sets the maximum amount of compression with lower values giving more compression.
TRIODE HARDNESS Controls how rapidly the power tubes enter saturation. Higher values give a more
aggressive character while lower values give a smoother breakup. This parameter defaults to an appropriate
value for each amp TYPE.
PREAMP BIAS Controls the bias point of the last triode (cathode follower not counted) in the virtual
preamp. Depending on the bias points of the previous stages, this can alter both the harmonic content and the
attack characteristics. Typically, if the previous stage has a negative bias then increasing this value will be
more noticeable and vice-versa.
POWER AMP BIAS Adjusts the offset voltage of the virtual power amp to vary the symmetry of the
clipping of the virtual power amp. A value of zero produces nearly symmetrical clipping with very little even
harmonics. Higher values are increasingly asymmetrical which increases even harmonics. Small amounts of
even harmonics can make the power amp distortion sound warmer and more bell-like while higher amounts
will give a fuzzier tone. Most amps have some amount of offset and the amp models will default to a typical
value. Note that this parameter is only applicable for push-pull power amp types. For single-ended power
amps the Power Tube Bias parameter sets the symmetry (as always).
Dont confuse this with POWER TUBE BIAS, which sets the quiescent operating current of the virtual power
tubes.
USE MIMIC This switches MIMIC processing on or off. For more on MIMIC, see the white paper
available on the support page of our web site.
TREM FREQ, TREM DEPTH These create true bias tremolo by varying the bias of the virtual power
tubes. Bias Tremolo is very organic and varies based on a multitude of variables including power amp settings,
damping, bias, and more. It is also self-ducking and decreases as you play harder. On some amp types,
extreme bias TREM DEPTH can result in excessive crossover distortion. On other amps the amount of tremolo
can vary greatly between loud and soft playing. All this, however, is part of the allure of bias tremolo as it
results in a particularly organic sound.

Factory cabs include custom creations by Fractal Audio Systems, selections from 3 -party libraries by
OwnHammer, RedWirez, and Kalthallen, TheAmpFactory, plus contributions from Fractal Artists John Petrucci,
James Santiago, and loudspeaker design engineer Jay Mitchell.
The cab block supports both standard (2048) resolution IRs, and newer UltraRes format IRs. UltraRes is a
proprietary format that enhances the resolution of an IR without added CPU burden or storage requirements.
Each Axe-Fx II preset can use two fully independent Cab blocks.
Cab Parameters
INPUT SELECT For use in the mono cab modes. This control determines how incoming stereo signals will
be processed. Options include inputting only LEFT or RIGHT channels, STEREO or SUM L+R. This can be used,
for example, to run two Cabinet blocks in parallel for stereo processing by setting one to Left and the other to
Right.
MODE Offers HI-/ULTRA-RES, NORMAL RES (formerly MONO LO-RES) and STEREO modes.
The CAB block can load two different IR formats: Standard Axe-Fx II (2048) Res and UltraRes. The MODE
parameter determines how a loaded IR is used to process audio. With MODE set to "HI-/ULTRA-RES", Standard
Res IRs load in High (2048) mode, while UltraRes IRs load in UltraRes mode. When MODE is set to "NORMAL
RES" (Formerly "LO RES MONO") all IRs load as "NORMAL" (1024.) STEREO mode gives you two "NORMAL"
(1024) IRs.

CAB (TYPE) Sets the cabinet type by selecting from FACTORY and USER IRs. Cabinet types are listed in
the table in section on p.158. The four SCRATCHPAD locations found at the end of the list are designed to
allow you to audition cabs before committing them to a memory location. This capability is especially useful
when user cab memory is full, or when you are using Cab-Lab (available from http://shop.fractalaudio.com).
Please note that the contents of the SCRATCHPADs are cleared every time you restart the Axe-Fx.
SPKR SIZE This control scales the IR to simulate shrinking or enlarging the virtual speaker. This effect can
be used to shift where the tone sits in a mix, or to create dramatic effects. Subtle settings (0.9-1.1) will
sound most natural. SPKR SIZE is not offered in STEREO modes or when the selected IR is running in UltraRes.
MIC (TYPE) Selects the microphone simulation type used. There are ten different types based on classic
guitar cabinet microphones.
Manufacturer and product names mentioned below are trademarks or registered trademarks of their respective owners,
which are in no way associated or affiliated with Fractal Audio Systems. The names are used only to illustrate sonic and
performance characteristics of the Axe-Fx II MIC TYPES.
PROXIMITY Simulates the classic proximity effect, causing an increase in bass or low frequency response
as proximity is increased. The PROXIMITY control has no effect when MIC TYPE is set to NONE.
PROXIMITY FREQ This allows tuning the frequency range over which the proximity effect occurs.
DELAY This short delay (0.000-1.000 ms) provides the ability to simulate microphone distance as employed
to create interesting phase or comb filter effects. Youll need to have two parallel cabs with different delay
settings to hear this. Furthermore, the effect is most pronounced when the cabs are summed to mono.
LINK Available only when the Cab MODE is set to STEREO, LINK turns the LEFT channel parameters into
master controls, which set identical values for LEFT and RIGHT parameters. You can still override the right
channel parameters values if desired.
ROOM LEVEL, ROOM SIZE These controls determine the level and virtual size of a room reverb

LOW-CUT/HI-CUT Adjusts the cutoff points of first order high-pass and low-pass filters. Increase the lowcut to reduce bass boom. Decrease the high-cut to darken the tone.
MOTOR DRIVE This models the effect of high power levels on the tone of the speaker. The Motor Drive
parameter controls the relative drive level and, therefore, the intensity of the effect.
AIR, AIR FREQ Adds air and sets the cutoff frequency to determine if it is dark or bright sounding.

NUMBER OF VOICES Each stereo channel in the chorus can have from one to four voices. Increasing the
number of voices increases the fullness of the effect. Use two voices for a vintage chorus effect, or use up to
eight for a lush, multi-layered ensemble.
RATE This controls the speed at which the chorus oscillates. Use low settings with higher depths for slowmoving sounds. Increase the rate and depth for vibrato effects. Set fully counterclockwise to sync the chorus
LFO to global LFO1. When RATE is shown in parenthesis, it is being set automatically by the TEMPO parameter
(see below). Set the TEMPO to NONE for manual control.
DEPTH Sets the delay modulation, which determines the amount of detune heard from each voice.
Tip: Rate and depth are usually used inversely (high rate/low depth or low rate/high depth), but other settings can also
produce

MIX Sets the ratio of wet and dry (duplicated from the MIX page). A setting of 50% produces the most
prominent effect. Try setting the mix to 100% for vibrato effects.
TEMPO Sets the chorus rate in rhythmic relation to the global tempo. For example, if the tempo is set to
1/4 and the global tempo is 120 BPM, the chorus modulation rate will automatically be set to 2 Hz (BPM/60

LOW CUT Adjusts the cutoff frequency of a high-pass filter at the output of the processed signal. This
control removes bass frequencies and can be useful to create chorus effects designed for bass guitar.
HIGH CUT Adjusts the cutoff frequency of a low-pass filter at the output of the processed signal.
Decreasing this value creates a darker chorus effect reminiscent of an age when typical effects were unable to
reproduce the full frequency spectrum. Lower this to achieve those sounds some might call warm.
LFO PHASE Adjusts the phase differential between left and right LFO waveforms, which creates a
noticeable effect on the stereo width of the chorus.
LFO TYPE Sets the shape of the modulation. Sine and Triangle are the most commonly used waveforms.
Note: Whenever the number of voices is set to more than two, the LFO type will be changed automatically to
SINE. If the number of voices is greater than two and the LFO type is changed to something other than
SINE, the number of voices will be reset to two.
See section 16.7 on p.163 for more information on LFO waveform shapes and phase.
AUTO DEPTH Scales DEPTH to create a consistent sound at any RATE. This control simplifies dialing in
musical results. For precise control or wild sounds, you may wish to turn it OFF.
PHASE REVERSE Allows Left, Right or both channels of the effect to be phase inverted.
DRIVE This control allows you to simulate the gentle distortion produced by overdriving an analog bucket
brigade delay chip of the type used in many vintage chorus effects. Set to zero for pristine clean.
WIDTH Widens the sound, creating a difference between left and right delay times by scaling the right time
downwards from the value set (see DELAY TIME, above) toward 1 ms as width goes from 0100%.
LFO2 RATE Adjusts the rate of the secondary LFO. This LFO modulates the primary LFO and can be used to
create more interesting effects.
DIMENSION MODE Allows simulating the famous Dimension style rackmount and pedal chorus units:
Off: Dimension mode is not active.
Low: A neutral version of the Dimension with no tonal coloration.
Med: Classic Dimension processing buttons 1-3. Set RATE and DEPTH to taste.
High: Classic Dimension processing button 4. Set RATE and DEPTH to taste.

AUTO Turns the Dynamic Attack filter on or off. Turning this switch ON automatically varies the ATTACK
rate according to the program material; the compressor will respond to faster transients with a faster attack.
LOOK AHEAD Despite fast attack times, a compressor can fail to catch very fast transients. Look Ahead
introduces a short audio delay so the compressors gain control stage has sufficient time to respond to the
detector, which is side-chained with no delay. Look ahead can reduce popping, especially when heavy
compression is used on very percussive sources.
MIX Sets the ratio of wet (compressed) and dry sounds. This should normally be set to 100%.
THRSH (Threshold) Sets the level at which automatic volume reduction will occur. When input power
exceeds the threshold, the compressor reduces output volume as set by the RATIO. (When the TYPE is set to
PEDAL, the THRESHOLD is hidden and automatically set to minus infinity).
SUSTAIN/RATIO In PEDAL type compression, SUSTAIN increases compression amount as the knob is
turned clockwise. In STUDIO type compression, SUSTAIN is replaced by RATIO, which sets the input-to-output
ratio for signals above the THRESHOLD. A ratio of 2.00 (2:1) means that an input that is 10 dB over the
threshold will increase the output by only 5 dB. A ratio of 10.00 (10:1) means that an input that is 10 dB over
the threshold is reduced to a mere 1 dB above. Setting the RATIO to INFINITY turns the compressor into a
limiter, reducing any level above the threshold to the threshold, applying a sort of ceiling or brick-wall
limiting above which nothing can rise.
ATT Attack rate sets how fast the Compressor reduces the volume once the threshold is exceeded. For
guitar, a fast attack rate often works best.
REL Release rate determines how quickly the output volume returns to normal once the input level falls
below the compressors threshold. Fast release rates can produce a snappy attack, but a setting that is too fast
can cause distortion if used in conjunction with fast attack times and high compression ratios. Slow release
times can keep the entire signal quiet, reducing the gain of passages even though they are below the set
threshold.
In general the release rate should be set slightly faster than the natural release rate of the program material.
An easy way to set the release rate is to strum a chord, watch the gain reduction meter (on PG2 of the EDIT
menu) and set RELEASE rate so the decay observed is slightly faster than the natural decay of the instrument.
EMPH EMPHASIS creates a cool effect similar to using a filter on the detector. It boosts highs at the
compressor input and then cuts them back to normal levels at the output. Apply this to prevent thumpy lows
from causing your compressor to pump.
KNEE The knee control softens the operation of the threshold and the ratio, introducing gain reduction
gradually as signals approach the threshold. With high compression ratios, a hard knee may produce abrupt
gain changes. A soft knee produces a more transparent effect since it causes the compressor to engage
gradually.
54
Doc v15.0b
EFFECTS GUIDE
MAKEUP Automatic Makeup gain, when turned ON, compensates the output level to maintain perceived
loudness at the current threshold and ratio. The LEVEL control can then be used for fine control.
DETECT Selects whether the compressor will use RMS (Root Mean Square), PEAK, or RMS + PEAK
detection. RMS detection is smoother and generally used to even out the level of the program material over a
long period of time. Peak detection, commonly used with guitar, is useful for fast limiting. RMS + Peak
combines the best attributes of both: the speed of a peak detector and the smoothness of an RMS detector.
FILTER Sets the frequency of a high-pass filter on the input of the compressors detector stage. Raising the
filter frequency can help prevent low frequencies from pumping the entire mix. Does NOT filter the output.
SCSEL SIDECHAIN SELECT determines which signal is used to feed the compressors detector. NONE is the
normal setting and selects the compressors input (sum of the rows feeding the block). You can also use the
input from a designated row, or either of the main inputs. The BLOCK L and BLOCK R options are useful when
the compressor follows an effect with one side out of phase (delay, chorus, enhancer).
LEFT LOW LEVEL Sets the level of the left input low-pass filter.

MSTR FDBK Master Feedback scales any and all feedback parameters on PG2 of the Delay. Note that the
range of this control is 0200%, making it possible (easy, in fact) to overload the feedback loop.
MIX This is a copy of the MIX control on the MIX page, placed here for easy adjustment of the wet/dry
balance without page flipping.
LEVEL This is a copy of the LEVEL control on the MIX page, placed here for easy adjustment of the overall
volume without page flipping.
TIME Sets the time of the delay in milliseconds When TIME is shown in parenthesis, it is being set
automatically by the TEMPO parameter (see below). Set TEMPO to NONE to regain manual control.
FEEDBK Sets the amount of delay feedback (a.k.a. regeneration) to determine the number of repeats.
Negative values phase invert the signal in the feedback loop.
ECHO PAN Controls the placement of the wet signal (the echoes) in the stereo image. Note that this is
different than the MIX page BALANCE control, which acts on the mix of both wet and dry.
REPEAT HOLD This switch defeats the inputs of the delay and captures the current feedback loop,
which plays infinitely, as long as the REPEAT HOLD switch remains ON.
TEMPO Sets the TIME parameter in rhythmic relation to the global tempo. For example, if the global tempo
is 120 BPM, and TEMPO is set to 1/4 (one echo per beat), time will be 500 ms. To ignore the global tempo,
set to NONE.
DRIVE Determines the amount of distortion created by a drive model in the delay path. Use this to simulate
the way cascading feedback overloads a tape or analog delay.
BIT REDUCTION This control makes it possible to create the lo-fi sounds of vintage digital delays. The
number shown is the number of bits to be subtracted from 24-bit full scale. To create a 16-bit delay, for
example, set BIT REDUCTION to 8 (24 8 = 16). Bit Reduction is often used with high-frequency rolloff.
RIGHT POST DELAY Widens echo sounds by adding 0100 milliseconds of delay at the right (wet) output.

57
EFFECTS GUIDE
Please be aware that because the MONO delay contains only one delay line, the two LFO PHASE parameters on its
MOD page have no effect. Similarly, the LFO TARGET parameters must be set to LEFT or BOTH for modulation to
occur.
TIME Sets the left delay time in milliseconds. When TIME is shown in parenthesis, it is being set
automatically by the TEMPO parameter (see below). Set TEMPO to NONE for manual control.
RATIO Sets the right channel time as a percentage of the left. 100% results in both channels having equal
delay time. Settings close to 100% (e.g. 99.6%) will subtly widen the echo sound, while ratios corresponding to
whole number relationships like 7:8 (87.5%), 3:4 (75%) or 1:2 (50%) will create interesting grooves.
SPREAD Controls stereo width by setting the pan position of the two delays from hard panned (100%) to
dead center (0%) to swapped hard pan (-100%).
REPEAT HOLD Defeats the inputs of the delay and captures the current feedback loop.
FEEDBACK L Sets the amount of feedback for the left channel to determine the number of repeats.
FEEDBACK R Sets the amount of delay feedback for the right channel. To preserve tail balance, this
control will be adjusted automatically when RATIO is changed. You may override automatic settings by setting
a new value here manually. Negative feedback values phase invert the signal in the feedback loop.
TEMPO Locks the TIME parameter in rhythmic relation to the global tempo.
DRIVE Sets the amount of distortion in the delay path.
BIT REDUCTION Sets the number of bits to be subtracted (from 24 bits), enabling lo-fi effects.
58

EFFECTS GUIDE
TIME L, TIME R Dual parameters to set the time of the left and right delay lines. When TIME is shown in
parenthesis, it is being set automatically by the TEMPO parameters (see below). Set TEMPO to NONE to
regain manual control.
LEVEL L, LEVEL R Dual parameters to independently set the volume levels of the dual delay lines.
MASTER PAN The panning of each voice is multiplied by this value. A value of 100% will result in each
voice being panned as set in the individual pan controls. A value of 0% will result in both voices being panned
to center. A value of -100% will reverse the position of the voices. You can use a modifier on this parameter to
move the voices around the stereo field in real time.
R TIME RATIO Allows the right delay line time to be reduced. Very for subtle TEMPO offsets!
TEMPO L, TEMPO R Dual parameters to lock the independent TIME L and/or TIME R parameters in
rhythmic relation to the global tempo. See the TEMPO section under the MONO DELAY config (p.57) for more
about the relationship between BPM and delay time in milliseconds.
FEEDBK L->L, FEEDBK R->R Dual parameters to independently set the amount of feedback for the left
and right channels, determining the number of repeats heard.
FEEDBK L->R, FEEDBK R->L Dual parameters to independently set the amounts of cross feedback for
the delay lines. This controls how much of the left delay line is fed back into the right and vice versa.
Negative values phase invert the signal in the feedback loop.
PAN L, PAN R Dual parameters to independently set the pan positions of the dual delay lines.
DRIVE Sets the amount of distortion in the delay path.
BIT REDUCTION Sets the number of bits to be subtracted (from 24 bits), enabling lo-fi effects.

EFFECTS GUIDE
SPREAD Controls stereo width by setting the pan position of the delay outputs from hard pan (100%) to
mono (0%) to swapped hard pan (-100%).
RATIO Allows altering the time difference between the two echoes of the ping-pong.
START FREQ, STOP FREQ These controls set the range of the filter sweeps.
RESONANCE Sets the resonance of the filter. Some might describe this as an intensity control.
SWEEP TYPE Sets the waveform of the LFO that controls the sweeps. See section 16.7 on p. 163 for more
information on LFO waveform shapes and phase.
TIME Sets the length of time that the delay line will record before reverse playback begins. When TIME is
shown in parenthesis, it is being set automatically by the TEMPO parameter (see below). Set TEMPO to NONE
for manual control.
FEEDBK Sets the amount of feedback to add additional repeats to the reversed snippets.
ECHO PAN Controls the placement of the wet (reverse playback) signal in the stereo field. Note that this is
different than the MIX page BALANCE control, which affects both wet and dry.

RUN When this is turned ON, the reverse playback process is active and can be heard. Turning RUN to OFF
will mute playback (though any samples in the buffer will still silently run out). This switch can be remotely
operated with a modifier (attached, for example, to a footswitch) to stop and start playback.
TRIG RESTART When this is set to ON the reverse playback restarts when triggered via the RUN control.
If set to OFF, playback continues from the current position. The combination of RUN+TRIG RESTART can be
used to precisely align reversed passages to certain moments in a performance or to re-align tempo-based
reversing to the groove.
Tip: If youre

with
a
sequencer,
assign
an
EXTERNAL
controller
and
re-trigger this every few bars to keep sync.
TEMPO Locks the TIME parameter in rhythmic relation to the global tempo. See the TEMPO section under
the MONO DELAY type (above) for more about the relationship between BPM and delay time in milliseconds.
XFADE TIME Sets the crossfade time between reverse audio snippets. When the playback position
approaches the delay time, a new snippet begins playback at time zero. The crossfade time controls how long
it takes for the old snippet to fade out and the new one to fade in. You can achieve interesting and rhythmic
variations by setting long crossfade times. For classic reverse delay sounds, set this at or near minimum value.
MOTOR SPEED Sets the relative speed of the tape motor from 50% to 200%. This parameter can be
modified in real time, making it possible to time warp delayed material.
NOTE: The effect of MOTOR SPEED is cumulative with that of the onboard LFOs (see Delay Common Parameters on p. 61). To

EFFECTS GUIDE
HEAD 1 TIME Sets the distance between the virtual record and play heads, in milliseconds. Note that time
heard will be shorter if MOTOR SPEED is increased above 1.0, or longer if below 1.0.
HEAD 1 TEMPO Locks the HEAD 1 TIME parameter in rhythmic relation to the global tempo. See the
TEMPO section under the MONO DELAY config (p. 66) for more information on tempo and time.
HEAD 2 RATIO The Axe-Fx II tape delay has two heads, or taps on the loop. This control sets the relative
position of the second playback head from zero to a maximum of 100%the HEAD 1 TIME value. Settings
close to 100% (e.g. 95%) can widen the echo sound, while values expressing whole number relationships like
2:8 (87.5%), 3:4 (75%), 2:3 (66%) or 1:2 (50%) create rhythmic grooves.
LEVEL 1, LEVEL 2 These set the output level of each of the playback heads.
FEEDBACK 1, FEEDBACK 2 These set the amount from each playback head to be routed back to the
recording head to create feedback or regeneration. Higher values will create a greater number of echoes
over time. Because each head replays its own feedback signals plus those of the other head, the sound can
very quickly become dense or even out of controland dangerously loud. Increase feedback settings slowly,
and watch the front panel clip LED as a warning indicator. Lowering MASTER FEEDBACK first can also help.
Negative values phase invert the signal in the feedback loop.
PAN 1, PAN 2 These place the outputs from each head within the stereo listening field.
Note that the MONO TAPE TYPE uses the TAPE CONFIG, but the STEREO TAPE uses the STEREO CONFIG.
LFO1 TYPE, LFO2 TYPE Sets the shape of the modulation. See section 16.7 on p. 163 for more
information on LFO waveform shapes. Remember that the shift in pitch is determined by the slope of the LFO,
so a TRIANGLE waveform actually creates a sound that you might expect from a SQUARE waveform.
LFO1 TARGET, LFO2 TARGET Sets whether the LEFT, RIGHT, or BOTH delay line(s) will be modulated.
(MONO, PINGPONG, and REVERSE configurations use only the LEFT delay line).
LFO1 RATE, LFO2 RATE Sets the delay time modulation speed. When any RATE is shown in parenthesis, it
is being set automatically by a TEMPO parameter (see below). Set the TEMPO to NONE for manual control.
LFO1 TEMPO, LFO2 TEMPO Sets the LFO rate in rhythmic relation to the global tempo. For example, if
the tempo is set to 1/4 and the global tempo is 120 BPM, the LFO rate will automatically be set to 2 Hz
(BPM/60 = Hz). To ignore the global tempo, set these controls to NONE.
LFO1 DEPTH, LFO2 DEPTH Sets the depth of delay time modulation.
LFO1 DEPTH RANGE, LFO2 DEPTH RANGE Sets the range of delay time modulation to LOW or HIGH.
LFO1 PHASE, LFO2 PHASE Sets the LFO phase offset for the right delay line. See section 16.7 on p. 163
for more information on LFO phase. Has no effect on MONO, REVERSE, and TAPE configs.

EFFECTS GUIDE
The MOD page also contains the ducking controls. Ducking causes the wet level to be lowered automatically
when the level of your playing goes above a set threshold. Then, when you play more quietly or pause, the effect
volume increases so that the echoes fill the spaces.
DUCKER ATTEN Attenuation sets the amount by which the effect volume will duck (decrease). A setting
of 20 dB, for example, will decrease the echoes by 20 dB when the input level is above the threshold. Set to
0.0 to defeat the ducker.
DUCKER THRSHLD Sets the trigger level of the ducker. If the input signal exceeds this value, the delayed
signal will be reduced by the amount set with the ATTENUATION control.
DUCKER REL TIME Sets how long it takes for the delay signal to return to normal when the input goes
below the threshold. A short value here causes the ducked echoes to return to full volume the moment you
stop playing. Longer times cause the levels to swell back more gradually.
Finally, the MOD page contains some other cool parameters.
DIFFUSION Sets the amount of echo diffusion. This causes the echoes to get blurry and can be used to
smooth the sound.
LOW CUT Sets the frequency of the low-cut filter. Increase for thinner sounds.
HIGH CUT Sets the frequency of the high-cut filter. Decrease for darker sounds.
SLOPE Sets the filter slopes, in dB per octave, of the high and low-cut filters.
Q Sets the resonance of the high and low-cut filters. High values create boosted peaks at the cutoff points.
FREQ 1, GAIN 1, Q 1 Controls for one of two peaking filters. Select the frequency to boost or cut, and set
Q to determine the width of the effect.
A Word on Spillover
The Axe-Fx II Delay is capable of spillover, which means that effect tails ring out when the effect is bypassed or
when you change presets. For more on this subject, please see Setting Up Spillover on p. 170.

TONE Determines the high/low character of the drive simulation, just as the tone knob on a pedal would.
LEVEL Sets the output level. Even a clean-sounding drive can be used to push an amp to more distortion.
MIX Controls the ratio of dry to wet. This should normally be set to 100%.
BAL Sets the left/right output balance of the block.
LOW CUT Controls the frequency of the input high-pass filter. Increase to prevent "flubby" distortion.
HIGH CUT Controls the frequency of the output low-pass filter. Lower this for a darker sound.
CLIP TYPE Controls the type of clipping circuit used for the distortion generation.
SLEW LIMIT Limits the large-signal frequency response. Turning up this control simulates the limited highfrequency response inherent in drive pedals using early op-amps. This parameter defaults to an appropriate
value when a type is selected.
BIAS Sets the bias point for the clipping circuit. Varying this setting controls the relative amount of even and
odd harmonics. Set very high or very low for a unique sputtering effect. Use caution, as setting this too high
or too low with certain clipper types can render the block inaudible.
BIT REDUCE Creates digital distortion by reducing the resolution of the audio signal. The number shown is
the number of bits that will be subtracted from 24-bit full scale. To create 4-bit audio, for example, set BIT
REDUCE to 20. Tip: It is supposed to sound nasty!
SAMPLE RATE Another nasty lo-fi distortion, Sample Rate reduction creates intentional aliasing effects.
INPUT SELECT The Drive block processes audio in mono. This control determines how incoming stereo
signals will be processed. Options include inputting only LEFT or RIGHT channels or SUM L+R (the default).
BYP MODE Sets the bypass mode of the block to MUTE or THRU. See Common Mix Parameters on p.116.

The FX Loop block has a MIX page with LEVEL, BALANCE, and BYPASS MODE parameters. See Common Mix
Parameters on p. 116 for more information.
Each Axe-Fx II preset can use one FX Loop block.
WIDTH Determines the character of the effect, shaping the bands of frequency separation.
DEPTH Determines how far to the left and right opposing frequency bands will be spread.
LOW CUT, HI CUT These set crossover frequencies to determine which parts of the signal will be
enhanced, and which parts will pass through unmodified. Increasing LOW CUT causes lower frequencies to
pass through unaffected. Decreasing HI CUT allows high frequencies to pass through unaffected.
WIDTH Sets a delay for the right channel from 020 ms. Adjust until the
desired effect is achieved. Certain frequencies may cancel each other out at
various settings, and effects can vary based on the position of the listener.
INVERT Allows phase inversion of the left or right channel (or both). Use
in conjunction with the width control to adjust apparent widening.
PAN L, PAN R Independent parameters to control the pan positions of the left and right output signals.
BAL The Balance control changes the relative volumes of the left or right outputs. Sometimes the enhancer
effect will cause a shift in the apparent stereo placement of sound. The balance control may be used to
compensate for this.
The Enhancer has no mix parameters or bypass mode modifier switch. Both types offer a LEVEL control.

PAN L, PAN R These controls allow you to adjust the placement of the left and right output signals for
stereo width adjustment or stereo-to-mono conversion.
BYP Sets the bypass mode of the block. See Common Mix Parameters on p.116 for more information.
Basic Parameters
TYPE This control instantly sets other Flanger parameters for useful sound settings. Types include: DIGITAL
MONO, DIGITAL STEREO, ANALOG MONO, ANALOG STEREO, THRU-ZERO, and STEREO JET.
TIME Adjusts the delay time from 010ms. This changes the character of the effect. Low values give a
phaser-like sound whereas high values are more ringy and metallic. Adjust to taste.
RATE Controls the frequency of the Low Frequency Oscillator, which varies delay time to create the sweep.
Use low settings rate with high depths for slow-moving sounds. Increase the rate for vibrato effects. Set fully
counterclockwise to sync the Flanger LFO to global LFO1. When RATE is shown in parenthesis, it is being set
automatically by the TEMPO parameter (see below). Set the TEMPO to NONE for manual control.
DEPTH Sets the maximum delay variation. Higher depths increase the amount of detuning. Usually, the rate
and depth settings should be varied inversely, so an increase in rate warrants a decrease in depth. Unique
sounds can also be obtained by ignoring this convention and using other combinations of rate and depth.
Doc v15.0b
69
EFFECTS GUIDE
FDBK Feedback sets the amount of wet signal fed back to the input. Extreme values give the flanger a more
intense quality as it produces sharp resonances in the frequency response. With negative FEEDBACK values, the
wet signals are out of phase with the dry, creating sounds with a different character than those created using
positive feedback.
Note that extreme feedback at minimum flanger DRIVE settings will cause a siren-like ringing oscillation.
MIX Sets the ratio of wet and dry (duplicated from the MIX page).
TEMPO Locks the flanger rate in rhythmic relation to the global tempo. For example, if the tempo is set to
1/4 and the global tempo is 120 BPM, the rate will automatically be set to 2 Hz (BPM/60 = Hz). To ignore the
global tempo set the tempo control to NONE.
Advanced Parameters
THROUGH ZERO Setting this to ON adds a delay to the dry path equal to half the sweep depth. This can
emulate true tape deck flanging, where one of the two tapes is first ahead of, and then behind, the other.
PHASE REVERSE Controls the phase of the wet output signal. Either or both channels can be inverted.
Use to increase the effect of through zero flanging.
HIGH CUT This filters the wet portion of the effect signal, gently rolling off treble at the set frequency with
a slope of 6db. Set to lower values for a darker flanging sound.
LOW CUT Adjusts the cutoff frequency of a high-pass filter in the flangers feedback loop, gently removing
bass frequencies as the value is increased for a thinner flanging sound.
DRIVE This control allows you to simulate the gentle distortion produced by overdriving an analog bucket
brigade delay chip of the type used in many vintage flanger effects. Set to zero for pristine clean.
LFO PHASE Adjusts the phase difference between the left and right LFO waveforms. For maximum stereo
spread, set this to 180 degrees. For mono flanging, set this to zero.
LFO HICUT Lowering this control filters the LFO waveform, rounding sharp turns in its shape. Certain
waveform types (saw, square, random) otherwise have discontinuities, which can cause clicks or pops as
their values jump from one extreme to another. Lowering the LFO HICUT frequency will mitigate this.
AUTO DEPTH Scales DEPTH to create a consistent sound at any RATE. This control simplifies dialing in
musical results, but for precise control or wild sounds you may wish to turn it OFF.
STEREO SPREAD Controls stereo width by setting the pan position of the two delays from hard panned
(100%) to dead center (0%).
DRY DELAY SHIFT When THRU ZERO (above) is engaged, this allows shifting the cancellation point from
the center of the waveform to the edge or anywhere in between.

THRSH (Threshold) Sets the level below which automatic volume reduction will occur. When input level is
lower than the threshold, the expander reduces output volume as set by the RATIO.
RATIO Sets the gain expansion ratio to determine how greatly signals below the threshold will be reduced.
For example, when a ratio of 2 is chosen, for every dB the input signal falls below the threshold, the output
signal will drop by 2 dB.
ATT Attack time. Sets how quickly the Gate/Expander restores the gain once the threshold is exceeded.
REL Release time. Sets how quickly the Gate/Expander reduces the gain once the signal has fallen below the
threshold.
HOLD Sets how long the Gate/Expander holds the gate open once the threshold has been exceeded.
SCSEL Selects the sidechain input source. NONE is the normal setting and selects the block input (sum of
the rows feeding the block) as the sidechain source. The other settings allow isolating a single row or main
input as the sidechain input. The other rows are summed as usual. By using a row or main input as the
sidechain input, you can use the Gate/Expander as a ducker or de-esser. You can also choose either of the
main inputs as sidechain sources, i.e. Input 1 or Input 2.
LOWCUT/LOCUT These sets the frequency of low- and hi-pass filters on the sidechain input. The filters
only shape the signal feeding the detector. They do not affect the tone of the signal at the outputs.

Each band can boost or cut up to 12 dB. The outermost bands are shelving filters.
Each of the modes can be run as Constant Q or Variable Q. In a variable Q equalizer, the bandwidth varies as a
function of boost/cut levels, such that lower boosts/cut levels result in a lower Q.
Two Passive EQ types are also offered: 4-band (Low, Low Mid, High Mid, and High) and 3-band (Low, Mid, High).
These passive EQ models capture the characteristic sound of vintage analog gear.
For any type, press ENTER while on PAGE 1 to reset all bands to flat.
The AMP block (p.39) has a built-in graphic equalizer at its output, making it unnecessary to follow it with a
separate GEQ. There is also a global, 10-band graphic equalizer on each output (p. 133), which can be used to
modify the sound of all presets at once.
The Graphic Equalizer is stereo-in/stereo-out. Its LEVEL, BALANCE, and BYPASS MODE parameters are covered in

EFFECTS GUIDE
PLAY This switch has two functions: use it to stop recording and begin playback, or use it to instantly stop
playback that is already rolling. A momentary switch can be assigned to PLAY for stutter effects.
ONCE Toggles auto-stop at loop-end, so that if playback is running, the looper will stop automatically
when it reaches the end of the loop. If playback is already stopped, ONCE will start playback, play through the
loop and then stop. You cannot go directly from RECORD to ONCE.
STACK Overdubs audio on an existing loop. Pressing it again stops the addition but playback continues.
Existing audio is faded every time through the loop based on the setting of the DUB MIX parameter on the
Loopers MIX page.
UNDO This removes the most recently recorded overdub. Undo removes a given take, defined as
everything between when you pressed STACK to start overdub recording and when you turned it off.
REV Pressing this reverses the direction of the Looper. Playback and STACK recording are supported.
HALF Slows the Loopers speed to half. Playback and normal or overdub recording are supported at half
speed. For double speed playback, record in half speed and then switch back to normal. Note: Halving the
speed slightly reduces high-end frequency response.
Each Axe-Fx II preset can use one Looper block.
THRESHOLD The Axe-Fx Looper can start recording automatically when the input exceeds a given level.
THRESH LEVEL sets the level that must be exceeded (at the input of the LOOPER) for recording to begin.
DUB MIX Actually located on the Loopers MIX page, this determines how much layers are reduced when
you STACK new layers. If you never want old layers to decay, set this to 100%, but be aware that adding
additional layers in this way can result in excessive signal and clipping.
PLAY IMMEDIATELY Turning this OFF disables automatic playback upon completion of recording.

Master Parameters
Most types have one or more MASTER parameters, summarized here. Not all MASTER parameters appear in
every type; those that do are at the top of menu PAGE 2. MASTER parameters scale the effects of other controls

Mix Parameters
All Multi-Delay types share a common MIX page with MIX, LEVEL, BALANCE, BYPASS MODE, and GLOBAL MIX
parameters. See Common Mix Parameters on p.116 for more information on these controls.
5.20.1
The Quad Tap Delay offers four taps, each of which extracts a signal from any point in the delay line. It is useful
for cool creative and rhythmic effects. Each tap has its own level and pan controls, plus a bandpass filter with
adjustable frequency and Q. Four feedback controls are provided, but the sum of the four feedbacks may not
exceed 100%. Notice that feedback from all four taps is summed at the input, so even if its output level is reduced
to 0%, a tap with any feedback value greater than zero will still be heard the next time another tap plays.
Figure 5-18 The Quad Tap Multi-Delay Block
Parameters
TEMPO 1,2,3,4 Sets the corresponding TIME parameter in rhythmic relation to the global tempo. For
example, if the global tempo is 120 BPM, and TEMPO is set to 1/4 (one echo per beat), time will be 500 ms.
To ignore the global tempo, set to NONE.
Doc v15.0b
79
EFFECTS GUIDE
TIME 1,2,3,4 Sets the time when the selected tap will be heard, from 0-2000 ms. When any TIME is shown
in parenthesis, it is being set automatically by the corresponding TEMPO parameter (see below). Set TEMPO to
NONE for manual control.
LEVEL 1,2,3,4 Sets the level at the output of the selected tap.
PAN 1,2,3,4 Sets the pan for the selected tap in the stereo mix.
FEEDBACK 1,2,3,4 Sets the level of the selected tap in the overall feedback blend. Note that the sum of
the four feedback values cannot exceed 100%. Negative values phase invert the signal in the feedback loop.
FREQ 1,2,3,4 Sets the center frequency of the bandpass filter for the selected tap.
Q 1,2,3,4 Sets the width of the bandpass filter for the selected tap. Higher values result in a narrower
range of frequencies passing through.
DIFFUSION Sets the mix level of the diffuser block that precedes the delay line. Diffusion smears
transients and can be used as a type of reverb for creating interesting ambience effects.
DIFFUSION TIME Longer times will smear transients over a longer period.
DUCKER ATTEN (Ducker Attenuation) Sets the amount by which the effect volume will duck (decrease). A
setting of 20 dB, for example, will decrease the echoes by 20 dB when the input level is above the threshold.
Set to 0.0 to defeat the ducker.
DUCKER THRSHLD (Ducker Threshold) Sets the trigger level of the ducker. If the input signal exceeds this
value, the delayed signal will be reduced by the amount set with the attenuation control.
DUCKER REL TIME Sets how long it takes for the delay signal to return to normal when the input drops
below the threshold. A short value here will cause the ducked echoes to pop back into the sonic forefront
the moment you stop playing. Longer times will cause the level to swell back in more gradually.
LFO 1 AS MASTER Locks the rates of the LFOs for taps 2, 3, and 4 to the settings for LFO1.
LFO 1,2,3,4 RATE Sets the rate of modulation for the selected tap. Remember that while LFO1 is set as
the master, the controls for 2, 3, and 4 will have no effect on the sound. When any RATE is shown in
parenthesis, it is being set automatically by the corresponding TEMPO parameter (see below). Set the TEMPO
to NONE for manual control.
LFO 1,2,3,4 TEMPO Synchronizes the rate of the LFO for the selected tap in relation to the global tempo.
For example, if the tempo is set to 1/4 and the global tempo is 120 BPM, the LFO rate will automatically be
set to 2 Hz (BPM/60 = Hz). To ignore the global tempo, set these controls to NONE.
LFO 1,2,3,4 DEPTH Sets the modulation depth for the selected tap. Remember that while LFO1 is set as
the master, the controls for 2, 3, and 4 will have no effect on the sound
5.20.2
Plex Delay
In terms of delay effects, a multiplexer, or plex, is a feedback network through which each of several delay lines
is fed back to itself and all the others. The result is a very smooth, reverb-like effect. When combined with
80
Doc v15.0b
EFFECTS GUIDE
modulation, the result is a huge and lush-sounding space effect that can have qualities of echo, reverb, and chorus
all at once. The Plex Delay uses four delay lines.
Figure 5-19 The Plex Delay Multi-Delay Type
Parameters
DECAY TIME Sets the amount of time required for the echoes to fade by adjusting the coefficients of the
feedback matrix. Use caution, as high decay times can result in instability.
DIFFUSION Sets the amount of cross coupling between delay lines. Higher values increase the density of
the echoes and result in a more reverb-like sound.
TEMPO 1,2,3,4 Sets the corresponding TIME parameter in rhythmic relation to the global tempo. For
example, if the global tempo is 120 BPM, and TEMPO is set to 1/4 (one echo per beat), time will be 500 ms.
To ignore the global tempo, set to NONE.
TIME 1,2,3,4 Sets the time before the selected tap will be heard, from 0-2000 ms. Setting these values to
prime numbers will result in a dense array of repeats. When any TIME is shown in parenthesis, it is being set
automatically by the corresponding TEMPO parameter (see below). Set TEMPO to NONE for manual control.
LEVEL 1,2,3,4 Sets the level at the output of the selected tap.
PAN 1,2,3,4 Sets the pan for the selected tap in the stereo mix.
LOW CUT, HIGH CUT Sets the cutoff frequency for gentle high and low-pass filters in the feedback loop
of the delays. These controls affect all four taps simultaneously.
DUCKER ATTEN (Ducker Attenuation) Sets how much the ducker reduces delay levels. A setting of 20 dB,
will decrease the echoes by 20 dB when the input level is above the threshold. Set to 0.0 to defeat the ducker.
DUCKER THRSHLD (Ducker Threshold) Sets the trigger level of the ducker. If the input signal exceeds this
value, the delayed signal will be reduced by the amount set with the attenuation control.
Doc v15.0b
81
EFFECTS GUIDE
DUCKER REL TIME Sets how long it takes for the delay signal to return to normal when the input drops
below the threshold. A short value here will cause the ducked echoes to return to full volume the moment you
stop playing. Longer times will cause the level to swell back gradually.
LFO 1 RATE Sets the rate of modulation. When RATE is shown in parenthesis, it is being set automatically
by the TEMPO parameter (see below). Set the TEMPO to NONE for manual control.
LFO 1 TEMPO Synchronizes the rate of the LFO in relation to the global tempo.
LFO 1 DEPTH Sets the modulation depth. Increasing modulation adds a chorus effect to the Plex Delay.
5.20.3
Plex Detune
The Plex Detune is based on the Plex Delay (5.20.2 above) but adds four high-quality pitch shifters with a range of
+/- 50 cents to the output of the delay taps. Like the LFOs of the Plex Delay, these shifters help create layered
effect tails rich with pitch variations. With the following exceptions, the Plex Detune is identical to the Plex Delay.
Figure 5-20 Plex Detune (and Plex Shift) Multi-Delay Type
CROSSFADE Sets the amount of overlap used in the granules of the pitch shifters. Lower settings give a
grainy sound, while higher values smooth the sound.
DETUNE 1,2,3,4 Sets the amount of detune within a range of +/- 50 cents. Small values create a subtle
shimmer; higher settings create descending or ascending cascades.
In comparison to the Plex Delay, the Plex Detune has no LFO or modulation parameters.
5.20.4
Plex Shift
The Plex Shift is nearly identical to the Plex Detune, which is itself very similar to the Plex Delay. Its pitch shifters,
however, are granted a two-octave range with SHIFT parameters. This sub-algorithm has the same parameters as
the Plex Detune (5.20.3, above) with two exceptions:
DIRECTION This determines whether small granules of audio in the pitch shifter are played back forward
or reversed. To understand how this works, imagine a word whose individual letters have been mirror-imaged
but are still in the correct left-to-right order (
). In this case, the letters are very short snippets of
82
Doc v15.0b
EFFECTS GUIDE
audio. These are reversed (and possibly pitch-shifted) but are played back in the order in which they were
recorded. The length of the snippets depends on the TIME setting of the tap.
SHIFT 1,2,3,4 This sets the amount of pitch shift applied at the output of each tap within a range of +/- 24
semitones.
5.20.5
Band Delay
The Band Delay, shown below, creates filter sweep echoes with a bandpass filter at the output of each of four
parallel delay lines.
Figure 5-21 The Band Delay Multi-Delay Type
5.20.6
The delay lines of the Quad Series Delay are connected end-to-end so that their times are compounded as the
signal travels from one to the next. Each line has its own output tap, however, so the output of any line can also be
heard as it enters the next delay in the series. If you then set each delay time to 100 ms, you would hear echoes at
100, 200, 300, and 400 ms after the input.
Figure 5-22 The Quad Series Multi-Delay Type
The parameters of the Quad Series Delay are identical to those of the Quad Tap delay (5.20.1 above), except for
the absence of the diffusor block controls, the FEEDBACK SEND and RETURN parameters, and the single FEEDBACK
control.
Doc v15.0b
83
EFFECTS GUIDE
FDBK SEND Specifies which delay output (14) should be tapped to feedback to the input.
FDBK RET Specifies which delay input (14) the feedback tap should be returned to.
FEEDBACK Sets the amount of feedback from the send to the return.
5.20.7
Ten-Tap Delay
The Ten-Tap Delay provides a unique way to control the time, pan, and spacing of one to ten separate echoes.
Instead of feedback, it uses an innovative DECAY control to determine how the level of the ten taps changes over
time. The levels of individual delay taps can also be adjusted from -80 to +20 dB. Pan is set as a SHAPE that can
change automatically as the taps progress.
MONO/STEREO Sets the mode of the Ten-Tap Delay. In mono mode, twice as much delay per tap is
possible.
DELAY TIME Sets the time between delay taps. When TIME is shown in parenthesis, it is being set
automatically by DELAY TEMPO (below). Set DELAY TEMPO to NONE for manual control.
DELAY TEMPO Sets the DELAY TIME in rhythmic relation to the global tempo.
NUMBER OF TAPS Sets the exact number of repeats.
DECAY Sets how rapidly the volumes of the repeats decay over time.
SHUFFLE Sets the amount of time-offset for the odd taps to give a shuffle feel to the repeats.
SPREAD In stereo mode, this sets the spread of the repeats. At maximum, the left channel is panned fully
left and the right channel fully right.
RATIO Sets the ratio of the left-to-right delay time in stereo mode.
PAN SHAPE Controls the shape of the panning as a function of tap number. The repeats can move slowly
from one side to the other (increasing or decreasing), stay constant, or move back and forth (sine).
Dynamic pan effects are disabled if the Ten-Tap Delay is set to STEREO mode.
PAN ALPHA Controls how quickly the repeats move as a function of tap number and pan shape. Higher
values produce a more pronounced effect. To alternate left-to-right, set the PAN SHAPE to SINE and the PAN
ALPHA to maximum.
LOW CUT Sets the cutoff point of the high-pass filter. Higher values produce a thinner sound.
HIGH CUT Sets the cutoff point of the low-pass filter. Lower values produce a darker sound.
TAP LEVEL (110) Sets the relative level of the selected tap.
84
Doc v15.0b
EFFECTS GUIDE
5.20.8
The Rhythm Tap Delay uses the same algorithm as the Ten-Tap Delay but allows you to create a custom rhythm of
repeats. You can enter the rhythm in three ways:
1.
2.
3.
The parameters for the Rhythm Tap Delay include those of the Ten-Tap Delay (5.20.7 above) plus the following:
FEEDBACK Sets the feedback level from the final repeat to the input of the delay line. You can use this in
conjunction with the decay to control the overall decay behavior. If you set decay to zero and feedback to a
moderate value, the pattern will repeat, getting quieter each time through.
QUANTIZE Quantizes the tap times to the entered note value. This can be used to aid in tapping in a
rhythm. The tap times will be rounded to the nearest multiple of the note duration. You can change this value
even after youve tapped in your rhythm.
LEARN Use this function to enter a rhythm by tapping. For LEARN to work, QUANTIZE must be turned OFF.
Use the
keys to select the LEARN Parameter
Turn the
wheel clockwise until <TAP ENTER> is displayed.
Tap the rhythm you want using the
button. Be sure to include a tap for the original (dry) signal.
When finished tapping, turn the
wheel to <DONE>.
TAP TIME 110 Sets the time of the tap (relative to the previous one) in ms or divisions (divs). Divs are
th
units with the QUANTIZE value length. For example, if QUANTIZE is set to 1/16 , each div is 1/16 note, and all
ths
tap times will sound some whole number of 16 after the preceding tap. If QUANTIZE is OFF, you can enter
millisecond values directly or use the LEARN feature (above). Times that have been learned may be further
adjusted manually.
Doc v15.0b

EFFECTS GUIDE
5.20.9
Diffusor
A diffuser uses feedback delays to increase density, smearing transients to create interesting reverb effects. At
certain time and feedback settings, taps can be heard individually, but the diffusor is typically used to create a lush
blanket of sound. This algorithm chains four diffusors in series and controls the matrix with a single feedback
parameter.
MASTER FEEDBACK Sets the feedback amount to determine density. Together with the individual delay
time settings, this determines the character of the effect and the amount of smear.
LFO 1 RATE Sets the rate of modulation to add a chorus-like sound to the tail of the effect.
LFO 1 TEMPO Synchronizes modulation to a rhythmic value in relation to the global tempo.
LFO 1 DEPTH Sets the modulation depth to determine the intensity of time variations/chorusing.
TEMPO 1,2,3,4 Sets the corresponding TIME parameter in rhythmic relation to the global tempo. For
example, if the global tempo is 120 BPM, and TEMPO is set to 1/4 (one echo per beat), time will be 500 ms.
To ignore the global tempo, set to NONE.
TIME 1,2,3,4 Sets the time of each diffusor from 0-2000 ms. When any TIME is shown in parenthesis, it is
being set automatically by the corresponding TEMPO parameter (see below). Set TEMPO to NONE for manual
control.
86
Doc v15.0b
EFFECTS GUIDE
Parameters
EFF TYPE Chooses between Tremolo and Panner.
RATE Controls the speed of the tremolo or panner effect. Set fully counterclockwise to sync the chorus LFO
to global LFO1. When RATE is shown in parenthesis, it is being set automatically by the TEMPO parameter (see
below). Set the TEMPO to NONE for manual control.
DEPTH / WIDTH Sets the intensity of the modulation. When WIDTH is set to more than 100%, the Panner
uses psychoacoustic effects to pan beyond the boundaries of the normal stereo image.
TEMPO Locks the rate to the global tempo. For example, if the global tempo is 120 BPM, and TEMPO is set
to a 1/4, the LFO rate will be 2 Hz (120 BPM / 60 seconds = 2). To ignore the global tempo, set the tempo
control to NONE.
LFO TYPE Selects the shape of the LFO waveform. Try experimenting with the Log or Exp waveforms.
DUTY This varies the duty cycleor symmetryof the Triangle, Square, and Trapezoid waveforms.
LFO PHASE Adjusts the phase angle of the LFOs right waveform. With extreme settings, the Tremolo turns
into a Panner and the Panner turns into a Tremolo!
See section 16.7 on p. 163 for more information on LFO waveform shapes, duty, and phase.
START PHASE In tremolo mode, determines where the LFO will start at the moment the block is engaged.
PAN CENTER In panner mode, this shifts the apparent center of the stereo image.
Tremolo/Panner Mix Parameters
The Tremolo/Panner block has a MIX page with LEVEL, BALANCE, and BYPASS MODE parameters.

the change should affect neighboring frequencies. The bands include a selectable-type low filter, three bell filters,
and a selectable-type high filter. Select the desired band using the
buttons and adjust parameters as
required. A graphical display depicts the response, showing the effects of all five bands at once.
Parametric EQ X/Y Channel Switching
Each instance of the PEQ block stores two fully independent sets of parameters called X and Y. Selecting between
these allows you to change all block settingsinstantlyat the touch of a switch or button (excluding any
Modifier assignments). See X/Y Switching on p. 36 for more information.
Each Axe-Fx II preset can use four Parametric EQ blocks.
Parameters
FREQ Sets the center or cutoff frequency for the selected band.
Q A measure of filter bandwidth around the center or cutoff frequency. Set a higher Q for narrower boosts
or cuts. Extreme Q-values may cause output clipping even though the apparent volume is low. Reduce the Q,
gain, or block output level if this occurs. Frequency and gain are kept constant as Q is adjusted in the three
examples below (showing the constant Q Peaking type):
Figure 5-25 Effect of Q on bell/peaking filters
Q exerts a different effect for BLOCKING or SHELVING EQ types, selectable for bands 1 and 5.
GAIN Sets the strength of the filter through a range of +/- 12 dB.
TYPE The first and last bands have a selectable filter type. This parameter selects between the three
available types.
Shelving This type equally boosts or cuts all frequencies above or below the specified frequency,
forming a shelf. The typical bass or treble controls of most devices are shelving EQs. Shelving 2 is a
Passive EQ type, with all the very musical response youd expect from a vintage piece, but without the
typical signal-to-noise issues.
Peaking A peak filter cuts or boosts around a center frequency. When you boost or cut, neighboring
frequencies are also affected somewhat, depending on the bandwidth, or Q, of the band. Bands 2, 3, and
4 are always set to this type.
Blocking The blocking filter is so named because it only allows frequencies above or below the cutoff
frequency to pass through. Band 1 is selectable as a low-blocking type and Band 5 is selectable as a highblocking type.

Basic Parameters
TYPE This sets other Phaser parameters for different useful sound settings. Types include: DIGITAL MONO,
DIGITAL STEREO, SCRIPT 45, SCRIPT 90, BLOCK 90, CLASSIC VIBE, STEREO 8-STAGE and BARBERPOLE.
RATE Sets the frequency of the LFO that controls the sweep. Set fully counterclockwise to sync to Global
LFO1 (p. 128). When RATE is shown in parenthesis, it is being set automatically by the TEMPO parameter (see
below). Set the TEMPO to NONE for manual control.
DEPTH Sets the depth of the LFO that controls the sweep. Set higher for more dramatic phasing effects.
FDBK Feedback, also known as regeneration or resonance, controls how pronounced the peaks and
notches are. This is largely responsible for the iconic sound we associate with a Phaser.
Doc v15.0b
89
EFFECTS GUIDE
TONE A simple tone control for the Phaser effect (wet only).
FREQ Sets the start frequency of the first stage filter. This, in combination with the depth control, controls
the sweep range of the notches. This parameter is repeated as START FREQ on the Advanced page.
(FREQUENCY is not used in the BARBERPOLE type.)
TEMPO Synchronizes the rate of the Phaser LFO in rhythmic relation to the global tempo. For example, if
the global tempo is 120 BPM, and TEMPO is set to a 1/4, the LFO rate will be 2 Hz (120 BPM / 60 seconds =
2). To ignore the global tempo set the tempo control to NONE. (Tempo is not used in BARBERPOLE type.)
Advanced Parameters
(All BASIC controls of the Phaser except TYPE are duplicated on the ADVANCED page for convenience).
ORDER Sets the number of phase shifting circuitsor stagesin increments of two. Different settings
have distinctly different sound qualities. For a more pronounced effect, increase the order.
LFO TYPE Selects the shape of the LFO, determining how the sweep changes over time. SINE or
TRIANGLE shapes will emulate classic phaser sounds. SAW shapes provide rising or falling effects, and
Exponential/Logarithmic shapes create a more extreme pulsing effect.
LFO PHASE Sets the phase difference of the right waveform of the phaser LFO. Values greater than 0
produce stereo phasing with 180, reproducing the legendary reverse sync setting of the worlds largest
phase shifter (which incidentally employed six stages per side in this mode.)
See section 16.7 on p.163 for more information on LFO waveform shapes and phase.
FREQ SPAN Sets the span of the filters. Higher values separate the resulting notches by greater amounts.
VIBE MODE Technically, this parameter sets the all-pass frequency spacing. But it would probably suffice
to say that if Jimi, Robin, and David had a favorite Axe-Fx II phaser setting, this would be it. The TYPE
parameter on the BASIC page can be used to get dial in classic vibe sounds instantly, or you can manually turn
this switch ON to experiment with your own settings.
BULB BIAS Allows you to control the quiescent current of the virtual light bulb used in Vibe Mode.
Varying this parameter controls how lumpy the frequency sweep behaves. Unlike a real 'vibe, the Axe-Fx II
compensates so that the center frequency doesnt change with the bias, allowing easier control of the sweep
range. This parameter has no effect if Vibe Mode is switched OFF.
FEEDBACK TAP Selects which phaser stage the feedback is returned to. Typically the feedback goes from
output to input, but some types require it to be fed back to the second stage. (Stages are numbered from 0, so
to return at the second stage, select 1 for FEEDBACK TAP.)

Common Parameters
The first menu page has several common parameters for the pitch block.
PITCH SOURCE The Pitch Shifter allows you to select a source for the shifter to use when making pitch
calculations.
GLOBAL In this mode, the pitch information comes from the global pitch detector connected directly to
the main inputs (L+R summed). The signal into this detector is unaffected by other effects in the current
preset and is usually the best choice for single note usage.
LOCAL In this mode the pitch information is detected and analyzed at the input of the pitch block. This
mode allows the detector to track the pitch of a delay or effect tail even after youve stopped playing. This
mode also considers the internal feedback of the Pitch Block when calculating pitch.
Doc v15.0b
91
EFFECTS GUIDE
Master Parameters
Several of the Pitch Shift types include MASTER parameters, detailed below.
MASTER PITCH Scales the SHIFT setting for each of the voices. For example, with VOICE 1 SHIFT at +12,
VOICE 2 SHIFT set to -12, and MASTER PITCH set to 50%, the shifts will be heard as VOICE 1: +6, VOICE 2: -6.
TRACK ADJ This control allows fine-tuning of the pitch shifter splice length. For large shifts, this control
can help improve the quality of the shifted note.

5.24.1
Detune
The Detune sub-algorithm creates two voices that are detuned between -50 and +50 cents (one quarter step) from
the input. This mode is useful for creating double-tracked sounds or chorus-like effects.
Figure 5-27 The Detune Pitch Shifter Type
VOICE 1 LEVEL, VOICE 2 LEVEL Sets the volume level of the selected voice.
VOICE 1 PAN, VOICE 2 PAN Sets the panning of the selected voice.
VOICE 1 DELAY, VOICE 2 DELAY Sets the delay time of the selected voice.
5.24.2
Fixed Harmony
The Fixed Harmony mode creates two voices at fixed intervals from the note played, with the possibility of using
feedback and/or delay to create cascades of upward/downward shifting.
Figure 5-28 The Fixed Harmony Pitch Shifter Type

93
EFFECTS GUIDE
INPUT MODE Specifies whether the incoming signal should be processed in stereo (as shown in the block
diagram above) or summed to mono and then sent to both voices.
VOICE1 DETUNE, VOICE 2 DETUNE Sets the detune amount of the voice in a range of +/- 50 cents.
VOICE1 SHIFT, VOICE2 SHIFT Sets the shift amount of the voice in a range of +/- 12 half-steps.
VOICE1 LEVEL, VOICE2 LEVEL Sets the volume level of the voice.
VOICE1 PAN, VOICE2 PAN Sets the panning of the voice.
VOICE1 DELAY, VOICE2 DELAY Sets the delay time of the voice. When a delay time is shown in
parenthesis, it is being set automatically by a TEMPO parameter (see below). Set the corresponding TEMPO to
NONE for manual control.
VOICE1 DLYTEMPO, VOICE2 DLYTEMPO Locks the corresponding TIME parameter in rhythmic
relation to the global tempo. For example, if the global tempo is 120 BPM, and TEMPO is set to 1/4 (one echo
per beat), time will be 500 ms. To ignore the global tempo, set to NONE.
VOICE1 FEEDBACK, VOICE 2 FEEDBACK Sets how much of the output signal is returned to the input
for shift-upon-shift effects. Using both feedback and delay (above) results in cool-sounding cascades.
5.24.3
Intelligent Harmony
The Intelligent Harmony Pitch Shifter block type creates harmonies within a certain musical key and scale. The
SCALES parameter taps a small onboard database of music theory data to adjust shift amounts based on which note
you play. This makes it possible, for instance, to harmonize a melody around a key center without the shifter
playing any wrong notes. (With due respect, YOU still need to play the right notes for this to work.) Between
the actual note played and the two shifted voices, three-note chords can be formed. Crank out some Maiden,
Boston, or Thin Lizzy all by yourself!
Figure 5-29 The Intelligent Harmony Pitch Shifter Type
VOICE1 DETUNE, VOICE 2 DETUNE Sets the detune amount of each voice within +/- 50 cents.
KEY Sets the key that the harmony will be in.

EFFECTS GUIDE
LEARN While learn is ON, the KEY parameter will automatically change to whatever single note you play.
Assign to a footswitch for modulations right in the middle of a phrase! Turn this OFF again to return to normal
harmonizer function.
SCALE Sets the scale or mode into which notes will be shifted.
TRACK MODE Sets how the harmony will track the input. SMOOTH allows the shifted note to follow bends
and vibrato in the input. STEPPED locks the harmony to the nearest chromatic tone.
GLIDE TIME Sets the rate at which the harmony shifts from the one pitch to another as different notes are
played.
TRACKING Allows fine-tuning the pitch shifter splice length. For large shifts, this control can help
improve the quality of the shifted note. TRACKING is the same as TRACK ADJ in other Pitch Shifter types.
VOICE1 HARMONY, VOICE 2 HARMONY Sets the scale degree that each voice will sound.
It is important to recognize that this is NOT a semitones control but a specification of which note in the
scale should be used. To hear how it works, or to audition any scale, set the KEY to G, play the open G string
and change the HARMONY value. Compare IONIAN (MAJ) to AEOLIAN (MIN) in this way and youll get the idea.
If the current scale contains more or less than seven notes, not including the tonic, (diminished, whole tone,
custom, etc.), you may need to use your ears or do a bit of math to identify how its degrees play out over
multiple octaves.
VOICE1 DELAY, VOICE 2 DELAY Sets the delay time of the voice in milliseconds.
VOICE1 DLYTEMPO, VOICE 2 DLYTEMPO Locks the delay time to the global tempo. For example, if
the global tempo is 120 BPM, and TEMPO is set to a quarter note 1/4, then the delay time will be 500 ms. To
ignore the global tempo, set the tempo control to NONE.
Custom Scale
The Intelligent Harmonizer allows you to create a custom scale and save it with the preset. To use this feature,
set the SCALE parameter (above) to CUSTOM, set the number of CUSTOM NOTES, and set up your scales notes
in any key based on an arbitrary TONIC. As with other scales, the actual KEY setting (above) determines how
your custom scale will be transposed and compared to the note played for creating custom harmonies.
In comparison to the Custom Shifter (5.24.9, below), in which any input note of the chromatic scale can be
shifted +/- 24 semitones, the Intelligent Harmonizer requires that your creations contain from four to eight
notes (including the tonic), and each scale degree must be at least step higher than the previous.
CUSTOM NOTES Sets the number of notes when using a custom scale. Custom scales can have between
four and eight notes.
TONIC This parameter has no effect on how the scale will sound in actual use but instead serves as an aid
so you can see an example of your custom scale transposed to any arbitrary key. Change this value and other
scale degrees will automatically update. It is the KEY parameter (above) which actually transposes your custom
scale for use during actual performance.

Classic Whammy
The whammy, first introduced in 1991, is a relative newcomer to the field of guitar effects. The Classic Whammy
brings all of the expected sounds to the Axe-Fx II. Its CONTROL parameter is designed to be operated remotely
using a modifier (p. 123), typically assigned to some source controlled by a pedal. In comparison to the Advanced
Whammy (p. 99) this type has only a few combinations of octave up/octave down.
Parameters
MODE Selects the Whammy mode:
UP 1 Octave
DOWN 1 octave
UP 2 Octaves
DOWN 2 octaves
UP/DOWN 1 Octaves
UP/DOWN 2 octaves
Figure 5-30 - The Classic Whammy Pitch Shifter Type
CONTROL Adjusts the output pitch. Attach to a controller for dynamic control of the pitch. See the Wah
pedal tutorial on p. 168 for more details on doing this.
The introduction to this section covers COMMON, MASTER, TRACKING, and MIX parameters.
5.24.5
Octave Divider
The Octave Divider simulates the classic analog effect and works by actually turning the input into a square wave
and then dividing the signal by two using flip-flops. Like the classic effect, this effect only works on single notes and
works best on notes above the fifth fret. Experiment with pickup selection and effect placement to achieve the
best results.
Shift 1 and Shift 2 are fixed at one and two octaves down.
Doc v15.0b

EFFECTS GUIDE
5.24.6
Crystals
The Crystals Pitch Shifter is similar to the Fixed Harmony mode (p. 93) but is designed for special effects. It
features much longer possible splice times inside the shifter, reverse shifting, and a flexible feedback
architecture.
Figure 5-32 The Crystals Pitch Shifter Type
VOICE1 DETUNE, VOICE 2 DETUNE Sets the detune amount of the voice in a range of +/- 50 cents.
VOICE1 SHIFT, VOICE2 SHIFT Sets the shift amount of the voice in a range of +/- 12 half-steps.
VOICE1 LEVEL, VOICE2 LEVEL Sets the volume level of the voice.
VOICE1 PAN, VOICE2 PAN Sets the panning of the voice.
VOICE1 DELAY, VOICE2 DELAY Sets the delay time of the voice. When a delay time is shown in
parenthesis, it is being set automatically by a TEMPO parameter (see below). Set the corresponding TEMPO to
NONE for manual control.
VOICE1 DLYTEMPO, VOICE2 DLYTEMPO Locks the corresponding TIME parameter in rhythmic
relation to the global tempo.
VOICE1 FEEDBACK, VOICE 2 FEEDBACK Sets the feedback of the voice to the input. By delaying and
feeding a voice back, strange pitch effects can be created as the note is shifted again and again.
FEEDBACK TYPE Selects the type of feedback. DUAL sends the individual voices back to their respective
delay lines. BOTH mixes the voices and sends them back to both delay lines. PING-PONG sends each voice to
the opposite delay line.
98
Doc v15.0b
EFFECTS GUIDE
For sake of explanation, the Crystal algorithm splicing parameters detailed below are not listed in the order in
which they appear on the display of the Axe-Fx II.
VOICE1 SPLICE, VOICE2 SPLICE Pitch shifting breaks a signal into pieces called granules. These are
manipulated individually and then spliced back together. This parameter sets the length of the granules in
milliseconds.
VOICE1 SPLTEMPO, VOICE1 SPLTEMPO Sets splice time in rhythmic relation to the global tempo.
DIRECTION Determines whether the processed granules are played back forwards or backwards. To
understand how reverse works, imagine a word whose individual letters have been mirror-imaged but are still
in the correct left-to-right order (
). The length of the snippets depends on the SPLICE settings (above).
CROSSFADE Sets the amount of overlap in the audio granules. A low setting will make the edges more
discrete, while a high setting will tend to blend splices together.
Example: Imagine that the shaded rectangle below represents an audio signal, like a piece of reel-to-reel tape.
5.24.7
Advanced Whammy
The Advanced Whammy is identical to the Classic Whammy (p. 97) except that its shift range may be set to any
custom number of semitones within a range of +/- 24.
Parameters
The parameters for the Advanced Whammy are the same as the Classic with the following differences:
START Sets the start pitch shift amount in semitones. This is the amount of pitch shift applied when the
CTRL knob is in the minimum position.
STOP Sets the stop pitch shift amount in semitones. This is the amount of pitch shift applied when the CTRL
knob is in the maximum position.
The introduction to this section covers COMMON, MASTER, TRACKING, and MIX parameters.

EFFECTS GUIDE
5.24.8
Arpeggiator
The Arpeggiator uses a 32-step sequencer to control the shift amount of a harmonizer so that complex arpeggio
patterns can be created from a single note. Arpeggios intelligently transpose inside the designated key/scale as
you play different notes. So, in the key of C (Ionian) Major, the note C natural will arpeggiate as C-E-G (C major),
but the note D natural will arpeggiate as D-F-A (d minor).
Figure 5-34 The Arpeggiator Pitch Shifter Type
Parameters
The Arpeggiator parameters are identical to those of the Intelligent Harmony shifter (p. 94) except as noted
below:
RUN When set to ON, the sequence starts. When set to OFF, the sequence stops and resets to the
beginning. Attach the Envelope Follower (p. 130) to re-trigger the sequence on each new note.
SCALE Sets the type of scale, or scale mode, that the notes of the arpeggio will be drawn from. Examples
are Ionian (major), Aeolian (minor), whole tone, etc. Set to CUSTOM to use custom scale tones (see Intelligent
Harmony above for details).
TEMPO Sets the duration of each sequencer step as a rhythmic value in relation to the global tempo.
GLIDE TIME Sets the rate at which the harmony shifts from one pitch to another as the arpeggio shifts.
AMPLITUDE SHAPE, PAN SHAPE Specifies how the volume or pan changes as the arpeggiator plays
through one cycle. See Megatap Delay (p. 75) for more detail on shapes and alpha.
AMPLITUDE ALPHA, PAN ALPHA Sets the acceleration of the rate of volume or pan change.
A setting of 0% results in no effect, while 100% results in an extreme effect.
100
Doc v15.0b
EFFECTS GUIDE
STAGE 1, 2, 3 16 SHIFT Tricky but ideally implemented for maximum flexibility, this parameter sets the
number of scale degrees that each note of the arpeggiator will be shifted above or below the note played.
Lets look at the example of a four-stage arpeggio with values of 0, 2, 4, and 7. Well place it in the key of C for
comfort, with a scale type of IONIAN (MAJOR). When we play a C, the arpeggio will be heard as C-E-G-C,
because:
C + 0 scale degrees = C
C + 2 scale degrees = E (CD, E)
C + 4 scale degrees = G (CD, E, F, G)
C + 7 scale degrees = C (CD, E, F, G, A, B, C)
Remember that the notes of the arpeggios and the steps required to arrive at them are drawn only
from the current key/scale. Scales with more or fewer than seven notes in one octave (diminished, whole
tone, custom, etc.) can require some mental math, and its sometimes easiest to just use your ears.
Tip: By choosing the CHROMATIC scale, you can create a pattern that ignores the notes you play and simply
shifts pitch by the specified number of semitones.
The introduction to this section covers COMMON, MASTER, TRACKING, and MIX parameters.
5.24.9
Custom Shifter
The Custom Shifter is identical to the Intelligent Harmony Pitch Shifter (p. 94) except that it uses the custom
scales tables stored in the global memory. See section 8.3 on p. 133 for more information on setting up global
scales.
VOICE 1 SCALE, VOICE 2 SCALE Selects the custom scale to use for each voice.
KEY This transposes both custom scales to the desired key. Internally the Axe-Fx II assumes all Custom
Scales have a root of A so this shift is relative to that note. For example, if your custom scale was in A major
and you wanted to perform in G major youd set KEY to G. If your custom scale was in B minor and you wanted
th
th
to play in E minor youd set KEY to D, since E is a 4 above B and D is a 4 above A.

EFFECTS GUIDE
The parameters of the Quad Chorus are divided across pages for Master, Chorus 14, Advanced, and Mix.
Master Parameters
TIME Scales the times set individually for each of the chorus voices.
RATE Sets the master rate against which the rates of LFOs 14 are set as multiples.
DEPTH Controls the overall depth of all chorus voices.
FDBK Feedback for all four voices is controlled solely by this parameter. Classic chorus would typically
require a setting of 0%, while flanging is possible with higher settings (though extreme settings can cause
runaway oscillation).
INPUT MODE The STEREO mode is shown above: left input feeds voices 1 and 2; right input feeds voices 3
and 4. In MONO mode, the two inputs are summed into all voices.
102
Doc v15.0b
EFFECTS GUIDE
TIME Sets the minimum time delay of the selected chorus voice. All modulation is positive/unipolar.
LEVEL Sets the output level of the selected chorus voice.
PAN Sets the panning of the selected chorus voice in the stereo field.
DEPTH Sets the modulation depth for the selected chorus voices MORPH blend of LFOs 1/2/3.
The depth of LFO 4 is set for all voices simultaneously via the MAIN DEPTH parameter on the advanced page.
LFO MORPH This parameter taps any one, or a blend of any two, of LFOs 1, 2, and 3 to use as a
modulation source for the current voice. The scale below shows how the percentage setting selects between
the LFOs. A value of 0% taps only LFO1, while 75% would be an even blend of LFO2 and LFO3.
Advanced Parameters
The MASTER parameters on the Advanced Page are duplicates of items on the MASTER page (detailed above).
WIDE MODE When this in set to ON, the modulation to voices 2 and 4 from their LFO MORPH outputs is
inverted to widen the stereo effect.
MAIN DEPTH Controls the depth of LFO4, which modulates all four chorus voices.
MAIN PHASE Sets the phase difference for the main LFO (LFO4) output to chorus voices 2 and 4.
LFO1 MASTER If this is set to ON, the controls for LFO 1 also control the rates.
LFO TYPE 14 Selects the type of LFO for each LFO.
LFO RATE MULT 14 Sets the rate of each LFO as a multiple of the MASTER RATE.
Note: MASTER RATE appears as RATE on the MASTER page and as MASTER RATE on the ADVANCED page.

Each Axe-Fx II preset can use two fully independent Resonator blocks.
Parameters
MODE The Resonator can operate in one of two modes.
MANUAL: Resonator/filter frequencies are set individually as desired from 10010,000 Hz.
CHORDAL: Resonator/filter frequencies are set automatically based on a setting for CHORD TYPE. A base
FREQUENCY scales all four voices to any pitch/key.
INGAIN At high feedback levels, overload can easily occur. This scales the level into the effect for control.
MASTER FREQ/FREQUENCY In MANUAL MODE, MASTER FREQUENCY scales the frequencies set
manually for the four resonators/filters. In CHORDAL MODE, this is replaced by FREQUENCY, which sets the
frequency for the chord root.

Notes
Simulates an actual room. This is the type to use when you want the most natural, realistic
reverb. Also great on vocals and percussion.
Similar to the Room a little less smooth with some response peaks and a unique character.
Use this when you want your reverb to stand out a little.
Simulates the sound of large, boxy chamber. Useful when you want a bright, resonant
reverb.
Simulates the sound of a vintage plate characterized by smooth yet bright sound.
Surround your tone with heavenly reverb in this incredible simulation of a grand space.
Simulates the classic electro-mechanical reverb effect.
Carlsbad has nothing on this monster. A vast, cavernous space.
Models a classic digital studio reverb.
Dont take this fantastic reverb for granite.
105
EFFECTS GUIDE
TIME Sets the decay time. This is the amount of time it takes for the reverb to vanish beyond the point of
perception. This is also known as the t60 time, referring to the amount of time required for the reverb to
decay to 0.001 of its initial value (-60 dB).
INPUT GAIN Sets input level into the reverb. Primarily for use with a pedal or other control to set the
Send to the reverb (allowing reverb to ring out even after the pedal is pulled back). In other situations this
should normally be set to 100%.
EARLY LEVEL Adjusts the relative level of the early reflections (has no effect for the Spring types.)
REVERB LEVEL Adjusts the relative volume level of the reverb tail.
COLOR Adjusts the high-frequency absorption for a darker or brighter reverb tail.
LF TIME, LF XOVER The Axe-Fx reverb algorithm is actually multi-band, allowing for very natural effects.
These parameters control decay time for the low band and the crossover frequency separating low and mid.
INPUT DIFFUSION Controls the amount of diffusion applied to the signal before it hits the main reverb
generator. Greater diffusion reduces distinctness and increases the density of the tail.
DIFFUSION TIME Controls the length of the input diffusor. Lower values simulate a small diffusion space.
Higher values simulate a large space.
WALL DIFFUSION Controls how quickly the reverb tails density builds. Lower values cause discrete
echoes to be heard for a longer time. Higher values cause the echo density to build rapidly.
ECHO DENSITY Controls the initial density of the reverb tail. Higher values give a smoother sound. Lower
values allow the individual repeats to be more easily discerned. This determines the overall smoothness of the
tail (along with the DIFFUSION and SIZE parameters.) Large SIZE values will make the individual echoes more
apparent, as will lower values of DIFFUSION. For legato sounds, a low DENSITY value may be more suitable. For
short, percussive sounds, a higher value may be more desirable as the reverb tail will be smoother.
PRE DELAY Adds extra delay before the reverb starts. The SIZE control automatically imparts a certain
amount of delay before the reverb starts. Use this control to add more delay if desired. For example, if the SIZE
is low, the reverb will start almost immediately. You can use this control to add some delay before the reverb
starts but keep the small-sounding size.
TAIL DELAY This delays the reverb tail independently of the reverbs early reflections. It can simulate the
sound of spaces in which reflections from surfaces at different distances reach the listener at different times.
106
Doc v15.0b
EFFECTS GUIDE
MOD DEPTH, MOD RATE These parameters controls modulation in the reverb tail for a dynamic effect
similar to chorusing. Modulation helps fill out the soundstage and makes the reverb sound fuller. For nonpitched instruments like drums, modulation may be undesirable. (Set depth to zero to defeat.) To dial in
modulation, turn the mix to max, adjust depth and rate, and then re-set the mix as desired.
MIC SPACING Sets the stereo width of early reflections by simulating moving mics in the virtual space.
STEREO WIDTH Determines the overall stereo separation of the reverb. Set to 0% for mono output.
NUMBER SPRINGS When the TYPE is set to SPRING, this sets the number of springs in the simulation.
SPRING TONE When the TYPE is set to SPRING, this changes the character, emphasizing different tonal
aspects of the simulation. Lower values create a darker tone.
SPRING DRIVE This simulates overdriving the circuit of the reverb when the TYPE is set to SPRING.
Reverb EQ Parameters
The reverb features a powerful equalizer with high and low-pass, plus two peaking-type filters.
LOW CUT Sets the frequency of the low-cut filter. Increase for thinner sounds.
HIGH CUT Sets the frequency of the high-cut filter. Decrease for darker sounds.
FREQ 1, GAIN 1, Q 1 Controls the first peaking filter. Select the frequency and amount to boost or cut.
Set Q to determine the width of the effect.
A Word on Spillover
The Axe-Fx II Reverb is capable of spillover, which means that effect tails ring out when the effect is bypassed or
when you change presets. For more on this subject, please see Setting Up Spillover on p. 170.

EFFECTS GUIDE
Parameters
FREQ Sets the frequency of the oscillator.
FMULT Sets the frequency multiplier for the oscillator. The actual oscillator frequency is the FREQ value
multiplied by the FMULT value.
TRACK When this is set to ON, the frequency of the oscillator tracks the input pitch. The actual frequency
is then the pitch multiplied by the FMULT value.
Parameters
RATE Controls the rate at which the "drum and rotor" spin. Connect this to a controller for real-time
control. When RATE is shown in parenthesis, it is being controlled by the tempo parameter (below). Set TEMPO
to NONE for manual rate control.
TEMPO Locks the rate to the global tempo. For example, if the global tempo is 120 BPM, and TEMPO is set
to a 1/4, the LFO rate will be 2 Hz (120 BPM / 60 seconds = 2). To ignore the global tempo set the tempo
control to NONE.
LOW DEPTH Sets the modulation depth of the drum. Higher settings provide a more pronounced throb.
HI DEPTH Sets the modulation depth of the rotor. To simulate a rotating drum-only cabinet, reduce this.
HI LEVEL Sets the output level of the rotor. Use this to balance the level between the drum and rotor.
108
Doc v15.0b
EFFECTS GUIDE
ROTOR LENGTH This parameter adjusts the length of the virtual high-frequency horn. Larger values
increase the amount of Doppler shift and result in a more intense effect.
LOW RATE MULTIPLIER Adjusts the speed of drum rotation compared to the rotor (which always spins
at the value set for TEMPO, above).
LOW TIME CONSTANT, HI TIME CONSTANT Sets acceleration/deceleration rates of the drum/rotor.
LF MIC SPACING, HF MIC SPACING These sets the placement of the (neutral-sounding) virtual mics,
determining the stereo width of the effect. Setting LF to zero (default) simulates a single mic (mono) on the
drum.
DRIVE Give your virtual rotary speaker the grind of the classic power amp with this overdrive control.
The Rotary Speaker has MIX, LEVEL, BALANCE, and BYPASS MODE controls. See Common Mix Parameters on p. 116.
Parameters
TYPE Sets the waveform to Sine, Triangle, Square, Sawtooth, Random, White Noise, Pink Noise, or OFF.
(Setting a synth voice to OFF helps conserve CPU usage).
FREQ If input tracking is set to OFF or ENV ONLY, this parameter sets the oscillator frequency.
SHIFT Shifts the frequency of the oscillator up or down in semitone steps.
TUNE Detunes the oscillator slightly. The oscillator can be detuned +/- 50 cents.
DUTY When using the TRIANGLE or SQUARE waveforms, this parameter controls the symmetry or pulse
width of the waveform.

CREATE a starting point preset on the Axe-Fx II, dialing it in as close as possible to the desired tone. Dont
forget to include the Tone Matching block, positioned where it can hear the reference signal and the
output of your starting preset in mono without effects that might impede analysis.
CONFIGURE the Tone Matching block input options and connect or route a reference signal to the Axe-Fx.
CAPTURE the reference and local signals (using X and Y buttons) and watch as frequency plots are drawn
in the display.
COMPARE the reference and local signals (pressing ENTER) to produce the final match.
COMPLETE the process by STORING the preset.
EXPORT PAGE
Tone Matching Data can be Exported directly to an onboard USER CAB memory or dumped to USB. If the
GLOBAL IR Capture Mode (see p. 166) is set to STANDARD any USER CABs will created in the original Axe-Fx II
IR format. Smoothing and Amount are applied before Standard cabs are exported.
If Capture Mode is ULTRA-RES the user cab will be the newer Ultra-Res format. Smoothing and Amount are not
applied to Ultra-Res cab exports. Dump to USB creates an .ir file containing (8k unprocessed) data for mixing in
Cab-Lab.
REF SOURCE This specifies the signal to be used for reference. For example, to reference the feed from a
mic on a live amp, you'll typically use INPUT 2. For a computer audio source, use USB.
REF CHAN, LOCAL CHAN Tone Matching operates in mono only. If the reference or local signal is stereo,
use these parameters to determine whether left, right, left/right summed channel should be used.
REF SOLO When set to ON the reference signal is sent directly to the block output and other block inputs
are muted. If you assign a footswitch to this function, you can easily compare the reference and the result.

Doc v15.0b
EFFECTS GUIDE
AVG TIME Determines how long of a time window is used when analyzing the reference signal.
AMOUNT Scales the Tone Match effect from full to flat, determining the magnitude of its effect.
MODE Selects between OFFLINE and LIVE modes. Use LIVE mode when you can play into both LOCAL and
REFERENCE amps at the same time.
SMOOTHING This reduces the prevalence of peaks and valleys in the IR to ease a notchy sound.
RESOLUTION Normally, you'll run this in HIGH mode. To save CPU, change to LOW mode, which sacrifices
50% of the match resolution but can still sound great.
Parameters
INSEL Selects the input to use for the synthesis (carrier) channel. This is the input to use for your guitar or
other instrument. The other input is then the analysis channel and is typically used for vocal input.
BANDS Selects the number of bands to use in the analysis and synthesis filter banks.
MIN FREQ Sets the frequency of the lowest filter band.
MAX FREQ Sets the frequency of the highest filter band.
RES Sets the Q, or bandwidth, of the filters. Higher values yield narrower filters.
SHIFT Shifts the frequency of the synthesis bands relative to the analysis bands. This allows you to change
the character of the vocoding to produce anonymous mob informant or chipmunk effects.
Doc v15.0b
111
EFFECTS GUIDE
HPMIX Sets the amount of high-pass filtered signal to mix in with the synthesis output. This can be used to
increase the intelligibility of the vocoding by allowing certain consonants and air sounds to pass right through.
MASTER LEVEL Sets the master level for all the synthesis filter outputs.
MASTER PAN Sets master panning for all the synthesis filter outputs. Individual control of the filter output
levels and panning is provided on dedicated menu pages. You can use these controls to fine-tune the filter
bank response and control the panning of the filter outputs.
LEVEL 116 These parameters appear as sliders across two pages. They set the out level for each of the 16

INPUT SELECT This control determines how incoming stereo signals will be passed. Options include
STEREO, LEFT ONLY, or RIGHT ONLY.

FMAX Sets the frequency of the filter when the frequency control is at its highest value.
RES Sets the resonance (Q) of the filter. Higher values give a more pronounced response.
TAPER Defines the Sweep Curve by allow selection from various popular potentiometer tapers.
DRIVE This simulates overdriving the circuit of the wah pedal.
Doc v15.0b
113
EFFECTS GUIDE
TRACK Sets the Q tracking of the filter. As the frequency is increased, the resonance will be decreased by
an amount proportional to this value. If this is zero, the resonance of the filter will be constant at all
frequencies. Classic wah pedals usually have a resonance that decreases with frequency due to design
limitations. This control can be used to mimic those pedals.
CONTROL Sets the position of the wah. Normally you would use a MODIFIER to assign this parameter for
real-time control, but simply dialing it in will give you a parked wah sound.
Parameters
THRESH Threshold control. Sets the level at which the Noise Gate will start its downward expansion. If the
input signal drops below this level, it will be attenuated by an amount controlled by the ratio.
NOTE: As of firmware version 14, the threshold can be modified globally for all presets at once using the
NOISEGATE OFFSET parameter found on the Global:Config page. See Configuration Parameters on p. 132.
RATIO Sets the downward expansion ratio of the noise gate, thereby determining how much quieter the
signal will sound when the gate is closed. The ratio acts as a multiplier to further reduce signals below the
threshold by a factor of x.
For example, with threshold is set to -50 and a ratio of 2.0, an input signal at -60 dB (10 dB below the
threshold) will actually sound 20 dB below the threshold, (so, -80 dB).
ATTACK Attack time control. Sets the rate at which the Noise Gate opens the gate.
RELEASE Release time control. Sets the rate at which the Noise Gate attenuates the signal once the
threshold has been crossed. Higher values will make the signal gradually fade once it drops below the
threshold.
LEVEL Controls level at the output of the noise gate. Can be used to boost the overall preset input level.

your guitar. This recreates the way that some classic effects (e.g. Vibe) load down the pickups, causing a change
in frequency response. The Axe-Fx II recreates this effect by switching various (real) resistors and a capacitor in and
out of the signal path.
In Auto mode, the impedance is automatically set based on the first active effect the input "sees."
Normally you will want to leave this on AUTO, but you may also select any of the following values manually. This

BAL 14 Each of these is connected to one row of the grid as shown above and determines the left-right
balance for the incoming signals. See BALANCE under Common Mix Parameters (below) for more information.
MAIN Sets the overall level of the main mix for the selected preset. Use this control to adjust the relative levels
of different presets, but be careful not to clip the main outputs.
This parameter can be adjusted via MIDI using the VOL INCR/VOL DECR feature. See section 9.4 on p. 138.

LEVEL As you would expect, the LEVEL controls set the output level of a block. Almost all LEVEL controls have
a range from -80.00 to +20.00 dB. Exceptions include the Compressor and Filter (+/-20.00 dB) and the Drive,
which ranges from 0-10 dB.

EFFECTS GUIDE
MUTE When the block is bypassed, wet and dry are totally silenced.
THRU When bypassed, the block is completely disengaged. None of its parameters have any effect on the
sound; it behaves exactly as a shunt would in its place.
With BYPASS MODE settings of MUTE FX IN or MUTE FX OUT, the LEVEL and BALANCE controls will still affect
the dry signal when a block is bypassed.
The MODIFIER slot of the BYPASS MODE parameter does not actually connect to the bypass mode parameter,
but to the blocks BYPASS SWITCH (the same one that the
button controls).
IMPORTANT: When a modifier is attached to this switch, it becomes the ONLY way that you can bypass
or engage the effect. If you find an effect that wont bypass/un-bypass, check this setting.
INPUT GAIN This parameter, available on reverb, pitch shift, and all three types of delay blocks,
determines the amount of signal fed to the effect portion of the block. It has no effect on the dry signal.
Within the block, this simulates the way an Aux Send would normally feed an effect routed in parallel.
GLOBAL MIX This switch determines whether or not the MIX setting of the selected effect will be subject
to an offset (+/- 50%) applied using the global EFFECTS MIX parameter (p. 132).
This feature is provided so you can design presets with the built-in ability for one-touch mix compensation in
playing environments that require more or less wet mix. It is offered on the following effect block types:

GLOBAL BLOCKS
6 Global Blocks
6.1 Introduction
The Global Blocks feature is completely new and exclusive to the Axe-Fx II. Those familiar with Global Amps from
previous Axe-Fx products will find this system greatly expanded and improved. Those new to the Axe-Fx will
appreciate how Global Blocks enable central control of blocks shared across multiple presets.
With this feature, links keep designated blocks in your presets synchronized to their global masters, which are
stored in a separate and independent memory area of the Axe-Fx II. Changes saved to a Global Block cause linked
blocks to update when the presets that contain them are recalled. Links to Global Blocks remain in place until you
manually remove themeven if you make and save other changes to the block or the preset!
This enables you to create a favorite sound setting and use it to create one or more global blocks. When you load
these into multiple presets, each with other different effects, mix levels, routingwhatever suits your needsthey
are automatically linked back to the original global entries. Now, as favorite (global) sound settings evolve (as we
all know these things tend to do) you no longer need to update all of the individual presets that rely on them.
You just save your tweaks into the Global Blocks, and the latest and greatest settings are automatically applied to
linked blocks as normal presets are recalled.
Any block instance (except Tone Match, but including the Input/Noise Gate) can link to a global block, with 10
global memories for each of them. Should you choose to REMOVE a link between a block and its global
counterpart, this leaves both the normal and the global blocks fully intact and able to be edited independently of
one another again.

Or, remove links to global blocks from each preset before dumping it. You can use the method
described above in section 6.2.4, or use one of two options described below:
i. Once a preset is stored with one or more links to Global Blocks, the RECALL:PRESET
screen displays an option to PRESS ENTER TO UNLINK. Doing so will unlink ALL global
blocks. You can then STORE or DUMP the preset with no risk missing data.
ii. At any time, you can use the STRIP GLOBAL DATA utility to unlink all global blocks in the
current preset. This is located on the PRESET page of the UTILITY menu.
Tip: You dont need to STORE after removing global blocks to dump a preset. If you want to keep the Global
Blocks version in your system, remove the links, dump the preset, and then discard the changes by NOT saving.

settings for 2 LFOs, 2 ADSRs, Envelope Follower, Sequencer, 4
Manual knobs and 2 Scene Controllers. These are accessed via

EXTERNAL CONTROLLERS
Each one of the 12 External Controllers must be assigned either
to the onboard
jack(s), or a MIDI CC# (0127) in the CTRL

but you can use external controllers for different things in
different presets.

button to show the MODIFIER screen.
Select a SOURCE to assign to the current parameter or
choose NONE to remove an existing modifier.
The graph shows the relationship between the
control source (x-axis) and the sound parameter

Back in the EDIT menu, a modified Knob, Slider, or Graph parameter will be animated as the
source changes. Modified text parameters do not update in this fashion.
The text box above a knob shows the value that was set before the modifier was applied.
You must STORE the current preset to make the modifier setting permanent.
To Remove a Modifier
To remove a modifier, just change its SOURCE parameter to NONE.
Lets assume that the controller called EXT 1 has already been set up (in the CTRL page of the I/O menu) for MIDI
CC# 16 (its default setting), and that we have connected a MIDI foot controller with an expression pedal that is set
up to send this same message on the correct MIDI channel. (In fact, this is the default setting for the EXPRESSION
PEDAL 2 jack on the MFC-101).
124
Doc v15.0b
7.2.1 Transformations
The MODIFIER screen also contains several parameters that enable you to set up a custom relationship between
changes at the source and changes in the destination parameter. This makes it possible to transform or tune the
feel and sound of a dynamic effect. This can be especially important when one control source is attached to
multiple different parameters.
The MIN and MAX parameters determine the range over which the controlled parameter will respond, using the
same units. For example, the MIN to MAX range for a LEVEL parameter might be set from -9 to +4 dB, while a delay
TIME might be set for 200400 ms.
The START, MID, END, and SLOPE settings are used to re-map the ways in which parameters respond to changes in
the source.
The SCALE and OFFSET parameters allow you to vertically resize or shift the modifier curve.

graph using the same units as the parameter being modified. This ultimately determines the relationship between
the source and the target parameter. The following examples illustrate MIN and MAX in action.
the shape of the curve, while SCALE shifts it up or down with reference to the axes. Curves pushed or pulled
outside the modifier graph boundaries will be clipped and replaced by line segments.

Doc v15.0b
7.2.3 Damping
If MODIFIERS add automation or remote-control in real time, damping allows these changes to happen in
stretched time. Normally, parameters change at the same rate as modifier sources. Their values may be remapped as we saw above, but changes happen simultaneously. Every little tremble of your foot is reflected by a
little tremble in the sound. DAMPING allows you to add hysteresisa little viscosity or elasticityso changes in
the parameter dont accelerate as quickly as those in the source.
At low settings, DAMPING adds a little smoothing. Try a setting of 412 ms to grease a wah or to ease the edges
of a step-sequence to eliminate clicks and pops. Medium settings can relax a whammy or cover up for a
scratchy expression pedal. With high damping, sound changes glide like honey. Quick motions are entirely
swallowed up, while a simple footswitch can be used to create a 1000-ms-long ramp of sound change. Used
appropriately, damping adds tremendous power to the MODIFIER system.
AUTOENG Determines whether or not the block containing a modifier will automatically engage or bypass
based on the level of a modifier source. The SPEED (SPD) options engage the effect when the controller
changes more than 5% in any 20 ms interval. The POSITION (POS) options engage the effect when the
controller value is 5% greater than or less than the OFF VALUE (depending upon whether the OFF VALUE is less
than or greater than 50% respectively).
For example, setting the Auto-Engage to SLOW SPD will bypass the effect when the controller value is less
than, say, 5% (default). To engage the effect the controller (foot pedal) must be moved more than 5% in a 20
ms interval. This requires that the pedal be moved somewhat rapidly and prevents the effect from engaging
erroneously if the pedal droops. Setting the Auto-Engage to SPD POS will bypass the effect in the same
manner but the effect will engage when the controller exceeds 10% (5% + 5%) regardless of the rate of
change.
OFF VAL Sets the threshold that the value of the current SOURCE must cross for auto-engage to occur.
When OFF VALUE is set below 50%, the effect is bypassed when the controller goes BELOW the OFF VALUE. If
OFF VALUE is set to 50% or higher, the effect is bypassed when the controller goes ABOVE than the OFF VALUE.
For HEEL down = bypassed, set to 5%. For TOE down = bypassed, set to 95%.
Use SLOW settings to loosen Auto Engage so your effect doesnt snap on or off unexpectedly. Set to OFF to
disable Auto Engage.

RATE Sets the frequency of the LFO from 0.0530.0 Hz. When RATE is shown in parenthesis, it is being
controlled by the tempo parameter (below). Set TEMPO to NONE for manual control.
128
Doc v15.0b
TEMPO Sets the LFO rate in rhythmic relation to the global tempo. For example, if the tempo is set to
1/8, the LFO will cycle twice per tempo beat (8x/measure). Tempo changes are reflected in real-time. To
ignore the global tempo, set the tempo control to NONE.
LFO1 and LFO2 are also subject to interesting interactive variations made possible by the modifier slots available
on their own parameters. See p. 163 of the Appendix for a guide to LFO Waveforms, Duty, and Phase.
QUANTIZE Divides continuous LFO waveforms into sample and hold segments.
In the diagram at right, a SIN wav is quantized as 3 values. (Use the TRI wav for
rhythmically equal segments.)
MODE The mode determines how the ADSR generator operates in response to signals above the threshold.
ONCE: The ADSR plays through when the threshold is exceeded.
LOOP: The ADSR loops as long as the signal is above the threshold.
SUSTAIN: The ADSR begins when the threshold is exceeded, but HOLDS at the sustain level until
the signal drops below the threshold, at which point the release phase occurs.
RETRIG When Retrigger is ON, the ADSR will reset to the beginning whenever the threshold is crossed from
below to above. If Retrigger is OFF, the ADSR must reach the end of its
release phase before it can be retriggered again.
ATTACK The envelope begins at zero and increases to 100% over the
duration of the attack time (A).
DECAY When the attack phase completes, the envelope descends for
the duration of the decay time (D) until it reaches the sustain level (L).
THRESHOLD Sets the level at which the LFO will be triggered (or re-triggered; see MODE above).
Doc v15.0b
129
7.3.3 Sequencer
Like any step-sequencer, that of the Axe-Fx II generates repetitive control patterns by looping through
a series of steps or stages, each of which outputs a specified value. The sequence can be run at a
specified rate or be synchronized to the global tempo. Press the front panel
button to find
the SEQUENCER page for the current preset.
RATE Sets the rate at which the sequence is stepped through. At 1 Hz, each step will last for 1 second.
When RATE is shown in parenthesis, it is being controlled by the tempo parameter (below). Set TEMPO to
NONE for manual control.
TEMPO Sets the sequencer rate in rhythmic relation to the global tempo. For example, if the tempo is set
to 1/16 the sequencer will play 16 steps per measure (4 beats). To ignore global tempo, set this to NONE.
RUN This parameter starts and stops the sequencer. When the sequencer is stopped, it remains at the value
set for STAGE 1 (see below). When using a MIDI CC via an external controller to toggle RUN, a value of 70 or
higher will START the LFO, and a value of 57 or lower will STOP the LFO (assuming default modifier settings for
IN/MAX/START/MID/END/SLOPE).

position, just
stop and restart periodically from your DAW/sequencer with a quick pair of OFF/ON messages at regular intervals. Assign
the CC# to an External controller (p. 131) and assign this as the source of the modifier on the RUN parameter.
STAGES Sets the number of steps in the looped sequence from 132. For example, if STAGES is set to 3,
the sequencer will play steps 1, 2, and 3 in constant rotation: 1,2,3,1,2,3,1,2,3,1,2,3
STAGE # Each of the STAGE parameters sets the value for one step of the sequence. You can randomize the
values of ALL steps in the sequence by pressing ENTER with any STAGE (or the STAGES parameter) selected.
THRESH The threshold controls the sensitivity of the Envelope Follower by setting the level at which
tracking kicks in or out. When the input level is greater than the threshold, the follower tracks it at the attack
rate. When the signal drops below this level, the output of the follower will decay to zero at the release rate.
ATTACK The rate at which the follower output follows signals increasing in power.
RELEASE The rate at which the follower output follows signals decreasing in power.
GAIN The gain control works like a classic sensitivity control to set the relationship between incoming
levels and outgoing control signals. By boosting the input of the envelope follower, GAIN allows a weaker
input signal to exert a greater effect.

menus that control sound settings across all presets and modes. Changes made in this area take effect
immediately without needing to be STORED. The settings for all global parameters are included in a backup of the

Description
POWER AMP
MODELLING
(OFF/ON)
Enables or disables power amp simulation for all AMP blocks in all presets. This capability
is provided for cases when the Axe-Fx II is used with a guitar-oriented/tube power amp
that contributes significantly to tone and dynamics. Having these characteristics applied
twice to the soundonce in the Axe-Fx II and once in the real power ampwould result
in an over-processed tone. Preamp (gain, tone, etc.), Graphic EQ, and Mixer (Level,
Balance, etc.) sections of the AMP block continue to affect the sound.
This parameter enables or disables all CAB block processing in all presets. The CAB blocks
will not physically appear to be bypassed, but they will act exactly as if they have been
replaced by shunts. Use this when you are using the Axe-Fx II with an amp powering real
guitar speaker cabinets or the sound will be muffled, muddy, and boomy.
Allows delays and reverbs tails to ring out or spill over across preset changes. You can
select whether DELAY, REVERB, or BOTH effects will spill over. Setting this to OFF causes
effect tails to be cleared upon preset change. See section 16.10 on p. 166 for more.
Allows you to boost or cut the MIX setting across all REVERB blocks in all presets at once.
Note that an offset applied here will NOT be reflected in the value shown in the EDIT
menu of the actual Reverb blocks. This capability is provided to compensate for the fact
that certain performance spaces may require more or less reverb across the board.
This parameter allows you to boost or cut the setting of the MIX parameter of all blocks
for which the GLOBAL MIX parameter is set to ON. This switch must be enabled on a
per-block/per-preset basis and is available on the following block types:

This feature is provided so you can design presets with the built-in ability to compensate
for how different performance spaces may require more or less wet mix.
Different environments (e.g. studios, stages) and different guitars create different levels
of noise interference. This parameter allows you to globally raise or lower the
THRESHOLD of the Noise Gate (p. 114). Note that if the THRESHOLD for a given preset is
set to OFF the Global Offset will have no effect.
This control provides +/- 12 dB of relative gain for all amp blocks and can be used to
adjust the gain of all presets to compensate for the differences between guitars.

GLOBAL PARAMETERS
Description
BANDS 110
(+/- 12 dB)
Output 1 and Output 2 are individually equipped with 10-band graphic equalizers for
fine-tuning of the tone across all presets. The outermost bands are shelf type filters.
These come in handy when using the Axe-Fx II in different acoustical environments, or
when you change amps/speakers with no opportunity to adjust your presets.
Output 1 settings apply to all instances of the Output 1 mix signal including the
Headphone jack, the OUT1 balanced jacks, the OUT1 unbalanced jacks, and signal
which may be routed to USB or DIGITAL OUTS.
One exception to note: when OUTPUT 2 ECHO is set to OUTPUT 1 in the I/O:AUDIO
menu, the global Graphic EQ setting for OUT1 is NOT copied to Output 2; Output 2 is
processed by its own global graphic equalizer in the usual way.
GAIN
(+/- 12 dB)
Output 2 settings apply to all instances of the Output 2 mix signal including the
Output 2 unbalanced jacks (FX send) and the Output 2 signal, which can be routed to
the DIGITAL OUTS. (See I/O:AUDIO on p. 134 for more on routing).
The GAIN slider to the right of the graphic equalizer can adjust the output signal at
the selected output by +/- 12 dB. This level adjustment happens in the digital domain,
and a boost can cause output clipping if not used judiciously. Conversely, a reduction
made here can provide a good temporary remedy until you have time to address a
multi-preset clipping problem.

Description
INSTR IN
(0-100%)
INPUT 1
(0-100%)
INPUT 2
(0-100%)
This scales the level of signal at the front panel INSTR input jack, determining its level
at the input of the A/D converter.
This scales the level of signal at the rear balanced 1/4 INPUT 1 jacks, determining
their level at the input of the A/D converter.
This scales the level of signal at the rear balanced 1/4 INPUT 2 jacks (FX RETURN),
determining their level at the input of the A/D converter.
Description
This selects which signal source should be routed to the Input of the grid. ANALOG
(IN 1) selects the front INSTR input jack or the rear INPUT 1 jacks, based on the
setting of INPUT 1 LEFT SELECT (below). When USB is selected, the Axe-Fx II will
process signals sent from the AXE-FX II OUT 0 and AXE-FX II OUT 1 audio outputs of
the connected computer. When SPDIF/AES is selected, digital inputs will be used.
When ANALOG (IN1) is selected as the Main Input Source (above), this determines
whether the front INSTR input jack or the rear IN1 LEFT/MONO jack should be used as
the LEFT channel of the input signal. This option defeats the jack that is NOT selected.
This determines whether the signal received at INPUT 1 will be processed in stereo or
mono, and, if in mono, whether the LEFT ONLY or a sum of both channels should be
used. For typical Guitar In/Processed Stereo Audio Out applications, use default
settings: MAIN INPUT SOURCE to ANALOG (IN1), INPUT 1 LEFT SELECT to FRONT, and
INPUT 1 MODE to LEFT ONLY.
This determines how the Axe-Fx II handles signals received at the balanced INPUT 2
(FX RETURN) jacks, setting whether they should be processed in stereo or mono,
and, if in mono, whether the LEFT ONLY or a sum of L+R channels should be used.
The outputs of the connected device and the nature of the source material will
determine which setting is best.

This determines how OUTPUT 1 signals will be processed after the output mixer of
the grid. This control makes it easy to use the same Axe-Fx II presets in a variety of
stereo and mono performance or recording environments. The decision to use SUM
L+R or COPY L>R should be based on the source material. See Mono and Stereo on p.
165 of the Appendix for more detail.
This is NOT a boost intended for use during musical performance, as you might find
on an amp or pedal. Rather, this parameter is designed to boost signals to the OUT1
D/A converters so they can operate as close to full-scale as possible, while
simultaneously padding converter outputs to lower the noise floor. To set, increase
boost/pad until hard playing on a loud preset causes the front panel OUT1 CLIP LED to
light. Then reduce the Boost/Pad setting a few dBs to prevent further clipping. Note
that the BOOST amount is also applied to outgoing DIGITAL or USB signals.
This determines whether signal at the OUTPUT 1 jacks will be normal or phaseinverted relative to its state at the output of the grid. This lets you compensate for
inversions elsewhere in the signal chain. (inverts BOTH channels of the stereo pair.
This determines how signals will be processed after leaving the output mixer of the FX
LOOP block, or after being created as a COPY of OUT 1 (see below). This control
makes it possible to use the same FX-LOOP-block-based presets in either stereo or
mono conditions, or to use OUT 2 to create a mono copy of the stereo signal
appearing at OUT 1. See Mono and Stereo on p. 165 of the Appendix for more on
using the Axe-Fx II in mono.
See OUTPUT 1 Boost/Pad, above.
See OUTPUT 1 Phase, above.
No, not as in repeats repeats repeats. Echo in this usage refers to an exact
simultaneous copy of a signal. The default value NONE connects Output 2 to the
inputs of the FX LOOP block (p. 66). Selecting OUTPUT 1 creates an exact copy of
the OUTPUT 1 signal at OUTPUT 2. Use this when you need to feed both front of
house and full-range monitors, for example, and want independent level control over
each using the front panel
knobs. Selecting INPUT 1 copies the raw
unprocessed INPUT 1 signal to OUTPUT 2, and is ideal for capturing a dry track for
reamping without using the FX Loop block or USB. Note that the echo feature will
not function when an FX Loop block is present in a preset as the FX Loop has priority.
This switch selects whether the S/PDIF or AES digital inputs and outputs are active.
Only one may be active at any time.
This selects the signal to feed both the digital outs: OUTPUT 1, OUTPUT 2, INPUT
Set this to lower values for less latency, set to higher values if experiencing distorted
audio. Low values generally work fine with Windows machines. OS X computers may
need higher values. Stop USB audio streaming when changing this value so as to allow
the buffer to reset properly. Streaming can be stopped by closing the application
sending data to the Axe-Fx or by disconnecting the USB cable.

INPUT/OUTPUT PARAMETERS
Description
MIDI CHANNEL
116, OMNI
MFC PORT (XL Only)
Disabled/FASLINK/EtherCON
MFC ECHO TO MIDI OUT
ON/OFF
Sets the channel on which the Axe-Fx II will receive MIDI messages. OMNI causes
the unit to respond to incoming messages on ANY channel.
Set this to the appropriate port when you have an MFC-101 MIDI Foot Controller
connected at either the FASLINK or ETHERCON port.
MIDI signals received from an MFC-101 at the FASLINK or Ethernet/EtherCON jacks
are never passed to the MIDI THRU. When you want to pass MIDI from an MFC-101
to a downstream device, enable this option to create a soft MIDI Thru at the MIDI
OUT port of the Axe-Fx II XL.
Turning this ON will cause MIDI data received at the MIDI IN port to be forwarded
to the MIDI OUT port, where it is merged with regular outbound MIDISysEx
dumps or Realtime Tuner/Tempo Sysex for example. Thru is disabled during
firmware update.
This parameter determines whether the Axe-Fx II will process or ignore incoming
MIDI program change messages.
This determines whether the Axe-Fx II will respond explicitly to MIDI program
change messages received, or whether it will re-map incoming program change
messages to load user-specified presets. For example, an incoming program change
message of 15 would normally recall preset 15 (or preset 16 if DISPLAY OFFSET is
on; see below). With Custom Mapping set up, program change message 15 might
be set to recall preset 100, or any other preset you choose.
These three parameters work to specify which preset and scene will be loaded for
each incoming program change message when MAPPING MODE is set to CUSTOM.
For example, if you select 15 for MAP FROM and MAP TO values of 100, and 2
incoming Program Change #15 will load Preset 100, scene 2 (or 101:2 if display
offset is on; see below).
Selects between one of two behaviors for scene recall via MIDI.
OFF (Default): Scene edits are retained across scene changes until you load an
entirely new preset or reload the current one. If you tweak Scene 1, switch to Scene
2, then back to scene 1, your tweaks will remain intact.
ON: Scene edits are lost when you change the scene without saving first. So if you
tweak scene 1, switch to Scene 2, then back to Scene 1, Scene 1 will have reverted
to its previously saved state. This makes scene changes feel more like traditional
preset changes.
This is 00 01 74 for the Axe-Fx II and cannot be modified.
Display Offset causes Axe-Fx II presets to appear to be numbered from 001 instead
of from 000. The offset does not change which preset is recalled by a given
Program Change message. Note: Display Offset requires a corresponding setting in a

This determines whether the Axe-Fx II should re-process or ignore a MIDI program
change command for the currently loaded preset. With this setting OFF, the current
preset will be reloaded (and changes discarded) if it is selected again via MIDI PC.
Turning this OFF allows you, for instance, to load a preset, use various MIDI instant
Access switches or pedals to bypass effects or otherwise modify the sound, and
then stomp on the footswitch that originally selected the preset to have it revert to
its saved state. With this setting ON, redundant PC messages are ignored.
Selectively determines whether real-time SysEx messages for TUNER and TEMPO
will appear at the MIDI OUT port. The default setting of ALL ensures that a
connected MFC-101 Midi Foot Controller will be able to show the Axe-Fx II Tuner
on the floor, and that its TEMPO LED will flash in time with the current Axe-Fx II
system tempo.
This setting changes the way MIDI data is handled between the computer and the
physical MIDI IN/OUT and MFC ports of the Axe-Fx II.
When Set to OFF:
1. Inbound MIDI data at the MIDI IN or MFC ports is processed by the Axe-Fx
II.
2. Inbound MIDI-over-USB data sent via the AXE-FX II MIDI OUT port of a
connected computer is processed by the Axe-Fx II.
When Set to ON:
1. Inbound MIDI data at the MIDI IN or MFC ports is processed by the Axe-Fx
II and also forwarded to the AXE-FX II MIDI OUT port of a connected
computer.
a. Use this so your host sequencer/DAW can record the MIDI data
generated by an expression pedal connected to the MFC-101.
b. Use this to connect a MIDI keyboard or other device to the MIDI
IN port of the Axe-Fx II and play plugins or record performances in
your host sequencer/DAW.
2. Inbound MIDI-over-USB data sent via the AXE-FX II MIDI OUT port of a
connected computer is processed by the Axe-Fx II and also forwarded to
the MIDI OUT and MFC ports.
a. Use this so your host sequencer/DAW can also control devices
chained at the MIDI OUT/THRU port of the Axe-Fx II: synth
rd
modules, 3 -party processors, etc.
b. Use this to send SysEx backups or firmware updates to an MFC101 connected at the MFC port.
Note that the USB ADAPTER MODE function is completely independent of the
setting for MIDI THRU (above). It is therefore possible, with both settings turned
ON, for the physical MIDI OUT/THRU port to sum/output four different sources
simultaneously: 1) The Axe-Fx II regular MIDI out functions; 2) events received at
the MIDI IN port; 3) events received at the MFC port; and 4) events received via
AXE-FX II MIDI OUT from a connected computer. Adapter mode is disabled during
firmware updates.

INPUT/OUTPUT PARAMETERS
MIDI PC OFFSET
0255
Adds the value specified to all incoming MIDI Program Change requests before they
are processed. This makes it possible, for instance, for the same foot controller
programs to access presets 0-127 for one gig, presets 128-255 for another, and
presets 256-383 for a third.
This specifies an initial value to be used for each of the 12 External Controllers (p.
131) until remote data is received. This also applies when the controller is absent.
For example, if you normally use an expression pedal to control the VOLUME block
in a particular preset, the absence of that pedal might mean that the preset gets
stuck in a silent position. Setting an initial value of 100% for the EXTERNAL
CONTROLLER mapped to that pedal would ensure that when the pedal is not
connected, the volume will be all the way up instead of all the way off.
Description
INPUT VOLUME
NONE/PEDAL/0-127
This controls the global input volume at the start of the preset chain and is useful to
assign when you want to emulate the behavior of a volume pedal between the guitar
and the amp. Changes in level equate to changes in distortion amount, and effect tails
ring out when volume is lowered.
This controls global OUTPUT 1 volume (after the presets output mixer) and is useful
to assign when you want to control playback levels without changing any other aspect
of the sound. Amplifier input levels are unaffected for consistent distortion at any
level, and effect tail levels will be adjusted as well.
This controls global OUTPUT 2 volume (after the output the FX Block, or after it is
copied from OUT1, see section 9.2). This is useful when you want to control playback
levels for OUT1 and OUT2 independently, without changing any other aspect of the
sound, or if you want a pedal to control the SEND level to an outboard device in the
loop.

or you may change levels +/-20 dB with a single sweep!
Every block instance in the inventory of the Axe-Fx II except FB SEND, FB RETURN,
and SHUNT can be set up with a global, dedicated MIDI CC assignment to control its
bypass state. The complete list of default effect bypass assignments can be found in
the Factory Defaults section of the Appendix.
The X/Y switching feature equips various Axe-Fx II blocks with dual independent sets
of parameters, making it possible to have two completely different switchable
settings for a single block. Data values from 063 will select the Y state, while values
from 64127 will select X. See section 4.4 on p. 36 for more on X/Y switching.

UTILITIES
10.5 IR Capture
Impulse Responses (IRs) allow the Axe-Fx to simulate the sonic properties of a real speaker system. The CAB block
(p. 48) is pre-loaded with Factory IRs for 130+ different speakers, while 500 User IR slots on the Axe-Fx II XL
(100 on the Mark II or original Axe-Fx II) allow you to load custom impulses. This utility allows you to measures the
frequency response of a real guitar cab (or other speaker) and save the result as a custom Impulse Responses (IR)
for use in the CAB block. To use the utility, you must connect the
Axe-Fx II to a power amp and speaker so the test tones may be
played, connect a mic and preamp to the input of the Axe-Fx II so
the resulting response may be captured, perform the test, name,
and save the IR to a USER slot.

Doc v15.0b
UTILITIES
is filled with excellent info on mic placement, distance, angle, etc., but dont be afraid to experiment. Being able to
hear what the mic hears by placing the cab in isolation will help produce desired results quickly.
A preamp brings the signal of the mic up to line level for processing. This also contributes to the tone, but even the
simple preamp in an inexpensive mixer can produce excellent results. Do not apply dynamics processing (e.g.
compression) as this will misrepresent the response. With an optional mixer, multiple microphones can be
combined to produce a blended tone. Note however that it is also possible to capture mics individually and then
blend them in a preset using Cab-Lab or multiple Cab blocks. Leave your guitar connected and monitors powered
on so you can audition results when the capture is finished. Refer to the diagram here and make connections as
follows:
1.

3.
4.
Mic the cab, which should be in a quiet, isolated place where background noise wont be a problem.
Connect the mic to the preamp input and connect the preamp output to the INPUT 2 Left (
) of
the Axe-Fx II.
Connect OUTPUT 2 Left (
) of the Axe-Fx II to the input of your power amp input.
Connect the power amps speaker out to your speaker cabinet. Turn the preamp and power amp ON.
7.
8.
9.
To audition your saved IR, change the CAB of the current preset to the USER cab number where you saved the
custom IR. You can combine multiple IRs using multiple CAB blocks or the Stereo cab mode. When an IR is stored
to a slot that is already in use in the currently loaded preset, it will be heard immediately upon saving.
It is also possible to use this utility to capture the responses of systems other than a power amp/mic/preamp.
Possibilities might include the factory cabs of the Axe-Fx Ultra, a particular tape delay, or any other line-in/line-out
device.

TUNER
11 Tuner
The Axe-Fx II includes a state-of-the art onboard TUNER, an essential tool for the performing or recording
musician. It is easy to operate and features high-resolution automatic pitch detection, a calibration control, offsets
for modified tuning schemes, and the option to mute audio while tuning. The
button shows the tuner. The
buttons allow access to the tuner CONFIG and OFFSET pages. To exit the tuner screen, press
or
. The tuner may be set up via the CONTROL page of the I/O menu (p. 138) to be remotely
engaged/disengaged using MIDI or the onboard Pedal Jack.
Firmware 6.0 increased the range of the Axe-Fx tuner so it is equally well suited for bass or drop-tune guitars, and
also added a spinner that rotates clockwise when the note being tuned is sharp and counterclockwise when flat.

TEMPO
12 Tempo
Tempo is used in electronic music for synchronizing different rates and times, whether inside one machine or
across different devices. The Global Tempo of the Axe-Fx II allows for both internal and external synchronization,
providing effects with a central BPM clock that can run autonomously or march to the rhythm of an upstream
device outputting MIDI Beat Clock. The tempo is available to control a variety of rates and times in the Axe-Fx II.
The tap function can also be controlled remotely by assigning a MIDI CC# or a footswitch connected to the
onboard
jack to TAP TEMPO in the Control page of the I/O menu (p. 138).
The Global Tempo will automatically synchronize to MIDI Beat Clock if it is detected at the
port or in the
incoming MIDI stream of the USB interface. The Axe-Fx II does not recognize MIDI Time Code or SMPTE, nor does it
transmit MIDI Beat Clock.
This requires that the SEND REALTIME SYSEX option in the MIDI page of the I/O menu be set to ALL or TEMPO.
146
Doc v15.0b
TEMPO
Tempo-synchronized sound functions track changes to Global Tempo in real time, increasing or decreasing as it
speeds up or slows down.
If a presets TEMPO TO USE parameter is set to PRESET, the Global Tempo will change to the saved BPM value
whenever that preset is loaded. Factory presets in the Axe-Fx II are saved with a tempo of 120 BPM and a TEMPO
TO USE setting of PRESET.
If a presets TEMPO TO USE parameter is instead set to GLOBAL, its saved BPM value will be ignored, and the
current Global Tempo will be used.

Dumping to a computer
The PRESET page of the UTILITY menu contains various utilities for dumping the memory of the Axe-Fx II. Dumps
are transmitted as MIDI System Exclusive data, or SysEx, which can be recorded for backup, sharing, editing, or
other purposes. Before executing a SysEx a dump, you must connect the Axe-Fx II to a computer. This might be via
rd
legacy MIDI or via USB. Youll need a data recorder, typically a 3 party utility such as MIDI Ox for PC
(http://www.midiox.com) or Snoize SysEx Librarian for Mac (http://www.snoize.com). The details of configuring
and operating these programs are beyond the scope of this manual, but help can be obtained through their
authors or at our forum (http://forum.fractalaudio.com).
Once you have the computer connected and a SysEx utility ready to receive a dump, select the appropriate entry
on the UTILITY:PRESET page and press
to begin transmission. There are options for dumping PRESETS,
BANKS, or SYSTEM to either MIDI or USB.
Dumping to MIDI
MIDI data appears at the MIDI OUT port (or OUT/THRU on the Mark II).
Note: On the Axe-Fx II XL, please set MFC ECHO TO MIDI OUT to OFF during MIDI transmissions.
DUMP PRESET TO MIDI dumps the currently loaded preset, including any unsaved changes, to the
MIDI OUT port of the Axe-Fx II. There is no onscreen confirmation when a PRESET dump initiates or
completes.
DUMP BANK A, B, C (and on the XL only, D) TO MIDI dumps a batch of 128 presets to the MIDI OUT
port of the Axe-Fx II. Bank A contains presets 0-127, B contains 128-255, C contains 256-383, and D
contains 384-511 on the Axe-Fx II XL (or 1-128, 129-256, 257-384, 385-513 when DISPLAY OFFSET (p.
136) is turned ON. An onscreen meter (Bank Transfer in Progress) indicates the progress as a bank
is transmitted.
NOTE: It takes approximately 9-10 minutes for a bank dump to complete via MIDI, so the meter moves very slowly.
USB (see below is dramatically faster! Again, we recommend using Fractal-Bot whenever possible.
DUMP SYSTEM TO MIDI dumps all of the system settings of the Axe-Fx II, specifically including:
All GLOBAL and I/O parameter settings
148
Doc v15.0b
Dumping to USB
Each of the DUMP TO USB options performs the same function as the corresponding DUMPTO MIDI
choice, except that the SysEx data is transmitted to the AXE-FX II MIDI IN port that appears in your computer
when the Axe-Fx II is installed/connected via USB.
13.1.2
Warning! Both BACKUP and RESTORE operations are permanent and cannot be UNDONE. When you
BACKUP to the onboard FLASH ROM, the old contents of the selected area will be irrevocably overwritten
by the new backup. When you RESTORE from the FLASH ROM, the selected Preset Memories or System
Settings of the Axe-Fx II will be overwritten by the restored data and cannot be recovered.
Doc v15.0b
149
Warning! Never interrupt a FLASH ROM Backup or Restore operation in process, or data loss/corruption
could occur. Do not unplug or power off the unit during BACKUP or RESTORE.
BACKUP BANK A, B, or C (Axe-Fx II Mark II Only!) copies a group of 128 presets to the onboard
backup ROM. Bank A contains presets 0-127, B contains 128-255, and C contains 256-383 (or 1-128,
129-256, and 257-384 when DISPLAY OFFSET [p. 136] is turned ON). A meter indicates progress. It
takes less than 10 seconds for a backup to complete.
BACKUP SYSTEM (every Axe-Fx II) copies all of the system settings of the Axe-Fx II to the onboard
Backup. Specifically, this includes:
All GLOBAL and I/O parameter settings
All TUNER settings
USER CAB IRs 1-50 (Axe-Fx II Mark II ONLY User Cabs are not part of an XL System dump!)
All GLOBAL BLOCKS
RESTORE USER BANK A, B, or C (Axe-Fx II Mark II Only) reads a group of 128 presets from the
onboard backup ROM and writes these into the onboard preset memories of the Axe-Fx II when you
press
to execute the selected function. Bank A contains presets 0-127, B contains 128-255,
and C contains 256-383 (or 1-128, 129-256, and 257-384 when DISPLAY OFFSET (p. 136) is turned ON.
RESTORE SYSTEM reads all of the non-preset settings of the Axe-Fx II from the onboard Backup ROM
and writes these into their respective areas when you press
. This specifically includes
All GLOBAL and I/O parameter settings
All TUNER settings
USER CAB IRs 1-50 (Cabs 51-100 are not included and must be restored separately.)
All saved GLOBAL PRESET settings
RESTORE FACTORY BANK A, B, or C reads from a separate different ROM memory which always
contains a fresh copy of the factory preset banks regardless of what changes you save to the preset
memories or backup ROM. These otherwise operate the same as RESTORE USER BANKS, above.
FETCH BACKUP PRESET loads an individual preset from the USER BANKS in ROM into the temporary
edit buffer of the Axe-Fx II. You need to STORE this preset manually.
FETCH FACTORY PRESET is the same as the above, except the preset is recalled from the FACTORY
ROM.
When the 2 Axe-Fx receives an individual preset, it does NOT store it. Rather, it loads it in the edit buffer which
must then be saved using normal methods (p. 37).
nd
When the 2 Axe-Fx receives a BANK or SYSTEM dump, it processes and stores the data immediately, overwriting
local presets and settings without warning. Remember that an Axe-Fx II must be rebooted immediately after it
receives a SYSTEM dump. It is not possible to connect one Axe-Fx II to another via USB.

TROUBLESHOOTING
14 Firmware Updates
As detailed in the UTILITIES section (p. 142), firmware is the built-in software that gives the Axe-Fx all of its
features, functions and capabilities. Through its capability for updates, the unit evolves, with additions,
enhancements and bug fixes. The firmware page in the UTILITY menu utility shows you the Version of the currently
installed firmware and includes a function to place the unit into an UPDATE mode.
Fractal-Bot
Fractal-Bot is hands-down the best way to upgrade firmware. This application for Mac or
Windows enables you to easily transmit updates quickly and easily. Its small, lightweight, and
has built-in step-by-step instructions. Visit http://www.fractalaudio.com/fractal-bot.php to
download Fractal-Bot.
Transmit the file from the computer to the Axe-Fx II. A progress bar will appear on the Axe-Fx II while
it receives the firmware. It will take several minutes to transfer the file.
If all goes well, the Axe-Fx will display "GOOD CHECKSUM and will then erase, flash and reboot.
If a firmware update fails, you may need to reboot the Axe-Fx II and try again after lowering the
rate at which your application sends SysEx data. This setting is typically called something like
Speed of sending MIDI, Delay between buffers, or Pause between played messages.
If you accidentally enter firmware upgrade mode, press EXIT or reboot the Axe-Fx II.
New firmware updates are made available through our website http://www.fractalaudio.com/support.

15 Troubleshooting
Fractal Audio Systems offers support through its web site at http://www.fractalaudio.com
You can also get answers to most questions in our online forum at http://forum.fractalaudio.com
The Axe-Fx Wiki at http://wiki.fractalaudio.com/axefx2 is also an excellent source of information.
Here are some frequently asked questions that might help you with very basic issues.
Q: How do I connect the Axe-Fx II to my computer?
A: Install the driver, available in the support section of our web site, and then connect the two devices together
with a standard USB cable. The Audio and MIDI ports will appear in your applications that support these functions.
Q: Can I use the Axe-Fx II with MIDI controller Brand X?
A: MIDI is MIDI. You wont get all of the deep integration features provided by Axe-Fx Mode on the MFC-101, nor
will you be able to connect via FASLINK or Ethernet/CON, but any device that can send MIDI program and control
change messages can interface with the Axe-Fx II.
Q: How do I set up a pedal to control a Wah?
A: See the tutorial on page 168.
Q: My Axe-Fx II is behaving erratically or froze up while I was using it. What should I do?
A: First try a simple reboot. If that doesnt work, Disconnect MIDI, USB and MFC and hold RECALL while you power
on the unit. This will load an EMPTY preset, but wont affect any of your saved settings.
Q: One or more of my presets produces no sound.
A: This might be any one (or several) of a number of things:
Is everything still wired up correctly? Most of the time, the problem is a faulty or disconnected cable!
Have you double-checked to ensure that you have a complete path from the input to the output? See
p. 30.
Is your guitar plugged into the front
versa? (See I/O : AUDIO on p. 134.)
Is there a MODIFIER assigned to a volume or level control while the pedal or external switch is not
present? Find and remove that modifier (p. 124) or change its EXT CTRL INIT VALUE from 0% to 100%
(p. 136).
Does the preset require a USER CAB which is not loaded? Try changing the CAB block to a Factory cab.
Q: The amps Ive dialed in sound wrong.
A: The amp simulations of the Axe-Fx II are extremely accurate and should sound instantly familiar to those who
know the original amplifiers that inspired them. If things dont sound correct, a few quick checks can confirm that
basic settings are correct. First, check the speaker cabinet type to make sure it is an appropriate match. You wont
get typical DAS METALL sounds from a 1x10 speaker! Next, consider the setting of the MASTER. If the original
amp had no master, try a high setting (8+) and then dial in the amount of distortion you want using the DRIVE
152
Doc v15.0b
TROUBLESHOOTING
parameter. Check the CONFIG page of the Global menu to make sure that power amp and cabinet simulations are
set correctly (see Chapter 3). Finally, consider trying default settings and the headphone jack for reference.
Q: All my presets suddenly sound harsh and bright. Whats going on here?
A: Check the CONFIG page of the Global menu (p. 132) to ensure that the Global Power Amp and Cab Simulations
have not been turned off. If a single preset is affected, make sure you havent set the SAG parameter of its AMP
block(s) fully counterclockwise. The Global Graphic EQ (p. 133) may also have an unusual setting.
Q: Many of my presets suddenly sound hollow and phasey. What could cause this?
A: These terms are sometimes used to describe the sound of problems caused when stereo sounds have been
summed to mono. Check the AUDIO page of the I/O menu to ensure that the OUTPUT1 MODE and OUTPUT 2 MODE
are set correctly according to how you are listening to your Axe-Fx II. Listening with headphones while making this
change can also confirm or rule out this possible problem.
Q: The sound is distorted even on what should be clean presets.
A: Check the input and output levels of the Axe-Fx II and check the input levels of any downstream amps/monitors.
See p. 15 for more on how to set levels. Also, try the obvious and turn DRIVE even lower on the amp, or consider
adjusting global AMP GAIN on the CONFIG page of the GLOBAL menu.
Q: The front panel CLIP LED is coming on. What does this mean?
A: The two CLIP LEDs indicate whether the D/A converters are being overdriven. See p. 15 for more on how to set
levels. Adjust the output levels of your presets, or reduce the global BOOST/PAD setting for the offending output.
In a pinch, you can also lower the GAIN setting on the Global Graphic EQ.
Q: My screen is blinking EXCESS CPU UTILIZATION! REDUCE LOAD.
A: First, try undoing the last change you made by turning the value wheel in the opposite direction. You can also
return to the grid, navigate around the message, and remove one or more blocks. You can also load a different
preset or reboot the unit. Changing CAB mode to MONO LO-RES is also a good solution in many cases.
Q: I am pressing FX BYP, but the state of the selected block will not toggle. Why is this not working?
A: The BYPASS MODE parameter, available on almost all blocks, has a modifier slot to control bypass state. Once
attached to this slot, the modifier assumes total control over the blocks bypass switch. Either utilize the MODIFIER
to change the bypass state, or remove it.
Q: I loaded a preset from a backup and it sounds nothing like it did when I first saved it. Whats wrong?
A: The most likely scenario is that something else changed: the firmware version, guitar, amp, or perhaps the
settings of external controllers. It is also possible that the preset uses Global Blocks that have changed.
Q: When I play audio from the computer through the Axe-Fx II, the sound is processed by the effects, and I cant
hear the guitar. Whats wrong?
A: Change the MAIN INPUT SELECT from USB to ANALOG (IN 1). This will allow you to play along with audio from
the computer.
Q: Can I use the onboard MIDI ports to connect a keyboard/synthesizer/etc. to my computer?
A: Yes. Just remember to turn on USB ADAPTER MODE in the MIDI page of the I/O menu. See p. 136.
Q: My Axe-Fx is warning me about presets not being installed correctly.
A: This rare error can be corrected through a series of simple steps. Visit http://support.fractalaudio.com

2. Connect the Axe-Fx II and the computer. This will typically be done using USB, but legacy MIDI also works.
3. Launch your MIDI Utility, ensure it is configured correctly to send SysEx to the Axe-Fx II, and ready it to send
the desired cab file. (Remember to set the Axe-Fx II as your applications MIDI device!)
4. Transmit the file from the computer to the Axe-Fx II. The Axe-Fx II will not show a progress bar, but its MIDI
IN LED will flash. There is no need to STORE or otherwise commit the change; it is permanent once
complete. If the IR File you transmitted has an embedded name, this will be displayed on the Axe-Fx II in
the bottom line of the CAB PG2 menu once the file has been received successfully.
The XL never includes Cabs in a SYSTEM dump/restore.
User Cab IRs 1-50 are included when you backup or restore the System area of an Axe-Fx II Mark II. See p. 148.
User Cabs 51-100 on the Mark II are not included in the SYSTEM and must be backed up or loaded individually.

LFO Phase
PHASE adjustments shift the alignment of the RIGHT or B LFO output. At 0 (below, far left), the two channels
are in phase; at 180 (below, far right), the two signals are phase-opposite, so while one is swinging from 0100,
the other is swinging from 1000 (and vice versa). Any interim setting is also allowed. Phase has no effect on the
Axe-Fx II RANDOM waveform.

Each Grid row is Stereo Many new users dont initially realize that a single path through the grid is
already in full stereo. You dont need two rows for this! There are four full-stereo paths, then, from the
input to the output.
What looks like this in the grid
is actually this.
2.
Different blocks process in different ways Some blocks (AMP, CAB, Drive, and the pedal compressor)
will sum the signal to mono at their inputs and process in mono, but the mono mix appears at both Left
and Right outputs for the block. Other blocksPing-Pong Delay or Reverb for instancesum the input to
mono but then process and output stereo signals. Other blocks, for example the chorus or wah, have
stereo inputs, stereo processing, and stereo outputs. The Effects Guide, beginning on p. 39, covers every
block and its processing in detail.
Mono Summing vs. Splitting When you need to run the Axe-Fx II in MONO, several options determine
how otherwise stereo signals will be processed:
a. Half-Stereo: By leaving the Axe-Fx II in stereo and connecting only the left main output to a
mono input, you get half-stereo. This works fine, with the caveat that the right channel will not
be heard! Panning will impart volume changes, and the Ping-Pong Delay and other wide effects
will need adjustment to be heard somewhat as intended. Tone may also change if panned cabs
or amps have been used.
3.
4.
5.
Doc v15.0b
b.
Summed Mono: By choosing SUM L+R mode for either OUTPUT 1 or OUTPUT 2, the two
channels are added together and the resulting signal produced at both LEFT and RIGHT jacks. This
has the advantage of including all sounds intended for both stereo channels, but short delay or
phase differences between channels can result in strange artifacts or even total cancellation. This
setting is best when youre confident that the presets youll be playing have been designed for,
or tested, in a SUMMED MONO listening environment. The Enhancer block and other short
delays could be problematic (including very short reverbs or the room simulator in the CAB
block). PHASE REVERSE switches should also be set to OFF when using this setting.
c.
Dual Mono: By choosing COPY L>R mode for either OUTPUT 1 or OUTPUT 2, you get a dual
mono signal. The sound will be identical to that of half-stereo, with the same limitations, except
it will be produced at both the left and right jacks. Use this setting when you want two mono
outputs without the problems typically caused by summing L+R.
Mono and Stereo at Once New for the Axe-Fx II is the ability to operate OUT2 as a summed MONO copy
of the stereo OUT1 signal (or vice versa). Select COPY OUT1>OUT2, then choose the output mode for each
pair of jacks that best suits your needs. See Mono Summing above for possible concerns.
The new Global Blocks feature (p. 118) allows the Enhancer and other width-sensitive delay effects to be
manipulated across multiple presets at once. It might be wise to employ this feature if you imagine
needing to use a number of presets in either stereo or mono situations.

Mixology
The MIXER and FX LOOP blocksand every presets output mixerall contain 4-channel mixers. As on a real
mixer, the LEVEL/GAIN parameters on the input channels determine what comes into the mixer. The overall mix
may then be acted upon by master output GAIN or LEVEL, and, where applicable, master balance controls.
The four channels of an Axe-Fx II mixer are wired to the four grid rows in the column to the left of
the mixer. In the first example at left, the level of Effect A would be controlled by the mixers
CHANNEL 1 LEVEL/GAIN control, because A is on grid row 1. Effect B would be controlled by Channel
2, because B is on row 2, and so on.
In the second example, the level of Effect Q would be controlled by the mixers CHANNEL 2
LEVEL/GAIN control, because Q is on row 2. Effect Z would be controlled by Channel 4, because Z is
on row 4. The location of the mixer never matters, only the location of blocks connected to its
inputs!
All mixer inputs are stereo. The BALANCE controls determine the left/right output balance of each channel. When
the balance for an input channel is set fully left, only the left channel of the block connected at that channel will be
heard at the mixers output; its right channel is silenced. Remember that every BLOCK in the Axe-Fx II has Left and
Right outs, even in cases where the signal is summed to dual mono (as is the case with the AMP, CAB, pedal type
Compressor, and, depending on their settings, certain other blocks as well).
Knowing what you now know about Axe-Fx II mixers, take a look at the Output mixer of a preset, located on the
MIX tab of its LAYOUT menu. On the surface, the output mixer looks like this:
But you can easily understand that these controls actually perform the functions illustrated below:
To review: channels 1-4 of the OUTPUT mixer are fed respectively by the stereo outputs of rows 1-4 of the grid.
Each channel has a LEVEL that determines the gain of the incoming signal (+/- 20dB) and a BALANCE control that
determines how the LEFT and RIGHT channels contribute to the final mix. A master GAIN slider offers +/-20 dB
control over the final mixed output.

Humbuster Technology
All 1/4" outputs of the Axe-Fx II feature our new Humbuster technology, which senses and subtracts the ground
noise of connected equipment using a simple stereo-to-mono cable. This provides up to a 20 dB reduction in
ground noise without resorting to dangerous "cheater plugs," expensive isolation transformers, or other noise
reduction devices or methods. It is especially helpful when using the Axe-Fx II with a device like an amp head,
which can both add and amplify ground hum, but it provides similar benefits when connecting to the 1/4"
unbalanced inputs of any device: full-range cabs, mixers, and other processors or devices. Humbuster technology
causes no signal loss or degradation.
To take advantage of this feature, you must connect the 1/4" output(s) of the Axe-Fx II to unbalanced 1/4" input(s)
of another device using a special TRS-to-TS cable. The wiring requirements for this cable are shown below.

16.15 Scenes
Note: A separate MINI MANUAL also covers SCENES. Find it on our web site support page.
In addition to amp and cab modeling, an Axe-Fx II preset can contain a number of pre- or post-effectsan entire
virtual guitar rig with tremendous flexibility and control. For flexibility and control in old-school rigs, a device
called a switcher is used to switch effects into or out of the signal path. Switchers also have presets, which reduce
tap-dancing by providing single-stomp access to different sets of pedals.
Until now, simulating this capability on the Axe-Fx has required multiple presets or fancy foot controller
programming. The multi-preset approach, however, was not without certain drawbacks. Setup and maintenance
could be challenging, changes were not always gapless, and it took care to get levels and spillover right.
To solve this we created SCENES. Every Axe-Fx II preset now contains eight SCENES. Each scene stores the BYPASS
setting for every block in the preset, the X/Y selection for those blocks that support it, the presets MAIN output
level, and the MAIN output of the FX LOOP block. Scene changes are seamless and instantaneous, with perfect
spillover requiring almost no effort. Scenes can easily be selected from the front panel or with a MIDI foot
controller such as the MFC-101.
In the example below, three scenes of an Axe-Fx II preset are shown. AMP and CAB remain ON in all three scenes.
In Scene 1 (S1, top) DELAY and REVERB are engaged. In Scene 2 (mid), DELAY is switched off, while COMPRESSOR
and PHASER are simultaneously switched ON. In Scene 3 (bottom), COMPRESSOR, DRIVE, CHORUS, MULTITAP
DELAY and REVERB are on. X-Y states and preset MAIN output level can also be set differently in each scene.
Doc v15.0b

To select a scene, turn the A QUICK CONTROL knob on the front panel of the Axe-Fx.
Scenes can also be selected via MIDI. See SCENES AND MIDI on p. 175.

APPENDIX
Scene Increment/Decrement
MIDI CCs can also be used to step up or down through scenes. The entries SCENE INCR and SCENE DECR in the
I/O:CTRL menu designate CCs for each action . The defaults are CC#123:INCREMENT and CC#124:DECREMENT.
Values from 64-127 trigger the action while values from 0-63 are ignored.
Scene Revert
This option on the MIDI page of the I/O menu selects between one of two behaviors for scene recall via MIDI.
With SCENE REVERT OFF (default) modifications to the current Scene are semi-permanent across scene
changes. So if you tweak Scene 1, switch to Scene 2, then back to scene 1, your tweaks will remain intactuntil
you load an entirely new preset or reload the current one.
Doc v15.0b
175
APPENDIX
With SCENE REVERT ON, modifications are lost when you change the scene without saving first. So if you tweak
scene 1, switch to Scene 2, then back to Scene 1, Scene 1 will have reverted to its previously saved state. This
makes scene changes feel more like traditional preset changes.
Just be aware of the fact that with SCENE REVERT OFF, you might easily forget about changes to one scene and
save the preset while a different scene is loaded. When setting up SCENES, it is recommended to set up and save
each scene one-by-one, and to test thoroughly.
rd
A caution for those using a 3 party MIDI controller: pre-programmed IA switch states which disagree with the
states you saved per SCENE will cause audio to glitch, IA LED states to not match the effect states heard, or worse

Eliminate conspicuous chorus pulsing with subtle RATE modification. Try an LFO or Envelope.
Modify the INPUT GAIN of a Delay or Reverb and create an EFFECTS SEND pedal to feed the effects.
Create a Power Saturation pedal to increase an amps MASTER while compensating its LEVEL.
Double-whammy goes UP and DOWNat the same time. (2 PITCH blocks, one pedal).
Create a groovy FILTER by assigning FREQUENCY to a QUANTIZED TRI wave LFO syncd to tempo.
Ducking reverb. Run the effect 100% wet (parallel to the dry) then use ENVELOPE to lower its level dynamically.
Place a low-pass or peaking FILTER in front of a DRIVE and control its frequency for foot tone fuzz.
Crossfade between two different signal paths by controlling different MIXER channels inversely.
Touch-Wahs are old news. Try an envelope-controlled FORMANT, PHASER, FLANGER, or RINGMOD.
Create a Ray-Gun. Modify Global LFO1 DEPTH with a pedal (0-100%). Assign LFO1 to the CONTROL parameter of a
Whammy (Pitch Block) set to +/- 1 8va.
Reclaim pedalboard real estate with a Wildcard footswitch. (Hi Dweezil!) Set it to the CC# of an External Controller.
Then assign this EXT source to the BYPASS MODE modifiers of different effects across different presets, or anything
else you can imagine...
Map SCENE CONTROLLER 1 to DRIVE to increase the number of amp sounds available within a single preset. Scene 1
might be fairly clean, Scene 2 light crunch, and scene 3 heavy drive. Try SCENE CONTROLLER 2 on MASTER!
Use the SEQUENCER to craft your own LFO shapes for a Phaser (FREQUENCY), FLANGER (TIME), FILTER (FREQ), or
Tremolo (use the VOLUME block). Applying some DAMPING in the modifier to change sudden steps into smooth
transitions. Assign another modifier set to an external source to SEQUENCER:RUN and youll have a way to start/stop
the new curves with your foot.
Traditional Rotary speakers have a SPEED footswitch. Its easy to assign ROTARY:RATE to any EXTERNAL source
connected to a latching footswitch. Use MIN and MAX on the modifier to set just how slow or how fast you want
each setting to be.
The MIXER block allows modifiers on every GAIN and BALANCE parameter. With SCENE controllers, this becomes an
extremely powerful way to route signals and meet diverse needs within a single preset. For example, two amps
could be panned hard left and right in SCENE 1, then dead center with a few dB knocked off in SCENE 2, etc.
Use the SEQUENCER in traditional fashion to change SHIFT of a SYNTH block for some On the Run action (or create
your own using this table (Hint, the front panel will only allow you to enter values with 0.1 precision, but Axe-Edit
allows you to enter 0.01 values ;-)

FRFR: Full range, flat response. This acronym is used to describe a neutral speaker or speaker system that is
designed to reproduce the entire audible spectrum of 20 Hz 20kHz without emphasis or de-emphasis. It is
invariably an approximation.
Hz: Hertz. The number of times something happens in one second. 4 Hz = 4x/second. Low values for Hz are useful
to describe RATESthe speed of a slow phasers sweep might be 0.33 Hz, for example (once every three
seconds). Hz are also the units used to plot low and high-frequency sounds. At the top of the frequency scale, units
of kilohertz (kHz or just k)thousands of cycles per secondare more useful. You will see both Hz and kHz on
equalizers, filters, and other effects that deal with sound as a spectrum of frequencies. With a little time, youll
learn to match the numbers with their effects on a sound. Check the web for more info, such as The Guitar Player
Book (2007, free on Google Books), or get yourself this cool t-shirt from Rational Acoustics:

APPENDIX
pF: Picofarads. Youll only see it on one parameter, the amps BRIGHT CAP value, where it affects treble response.
Phantom Power: By leveraging an unused pair of copper wires inside of a MIDI or other cable, the Phantom Power
system allows a single cable to carry both MIDI data and power between the Axe-Fx II and a connected floor unit.
Phase: This term is used to describe the position of one waveform relative to another. When two similar waves are
in phase, their peaks and valleys will line up exactly, reinforcing one another. Waves that are out of phase have
their peaks and valleys in opposition, so while one is headed up, the other is headed down. An LFO Phase control
settings allows left and right sweeps to be either synchronized or offset from one another. An Audio Phase control,
(such as the one in the Enhancer block or the PHASE REVERSE parameters of the Delay, Chorus, Flanger, and other
effects) flips the polarity of an audio signal. (Some might say this turns the waveform upside down.) Combining
two identical audio signals of opposite phase results in complete silence, explaining why you need to be careful
when summing to mono any preset with blocks that invert phase or shift time alignment.
Resonance: Resonance is an increase in amplitude around certain frequencies. It results in the intensification or
prolongation of certain components of a sound. In the Axe-Fx II, it is most commonly used in descriptions of the
Q parameter of a filter or parametric equalizer. At lower values, Q determines the slope of the effect, and at
higher settings, Q impacts the width and height of a peak that forms around the cutoff or center frequency.
RJ45: RJ45 is a type of standard connector cable end used in computer networking. Both Ethernet and its
ruggedized counterpart EtherCON utilize RJ45 plugs and jacks.
S/PDIF: Sony/Philips Digital InterFace
Semitones/Cents (ct or cts): Used to measure musical pitch. A semitone is one half-step, a.k.a. 1/12th of an
octavethe difference heard from one guitar fret to the next. A cent is 1/100th of a semitoneextremely small in
terms of your ability to hear a difference. Youll see these units on the Axe-Fx II Pitch Shifter and Synthesizer.
SysEx: Short for System Exclusive. A type of MIDI data that can be understood only by the particular make and
model of MIDI device that created it. On the Axe-Fx II, it is used for presets, banks, system backups, and User Cab
IR files, and to allow real-time control of the unit via a connected MFC-101 or computer running Axe-Edit (q.v.).
