Q&A
Note: To hear your guitar’s dry signal without the GR-20 synth sound, connect the GR-20’s GUITAR OUT jack to a
different amp or effects processor. No synth sound comes out of this jack.
Note: We’re assuming here that you’ve already set the GR-20 to Guitar or Bass mode, depending on the instrument
you’re using. To learn how to switch between these modes, see Page 32 in the GR-20 Owner’s Manual.
Tip: You can also select each string for setup by pressing the HOLD and/or GLIDE pedal.
5 When you’re finished, press the SENS button so it’s not lit, or press EXIT.
1 Turn the LEVEL knob on the GR-20’s rear panel to its MAX position. (Adjust the volume of your amp, mixer,
or PA if necessary.)
2 Turn the GK-3’s pickup volume all the way clockwise.
3 Turn the BANK dial to the PIANO position.
4 Turn the NUMBER/VALUE dial to select 06.
5 Confirm that the GR-20’s Expression pedal is fully in its toe-forward position.
6 Play the GR-20’s piano sound on your guitar, experimenting with your playing technique. Try plucking the
strings instead of strumming, for example.
7 Turn the BANK dial to the ORGAN/Kb position and turn the NUMBER/VALUE dial to select 01.
8 Play your guitar. While you’re playing this patch, use the Expression pedal to control the patch’s rotary-
speaker effect.
9 Turn the BANK dial to RHYTHM/PERC and use the NUMBER/VALUE dial to select 31.
10 Play the low E string, and then press and hold the HOLD pedal. While the loop is playing back, play other
strings.
11 Continue to select and audition other GR-20 patches using the BANK knob and NUMBER/VALUE dial.
Tip: You can also use the GK-3’s S1 and S2 buttons to scroll through the GR-20’s patches.
1 Make sure you’re connected to your amp, mixer, or PA using the GR-20’s
• R (MONO) OUTPUT jack—for mono.
• R (MONO) OUTPUT and L (PHONES) OUTPUT jacks—for stereo.
Note: You can’t use the GR-20’s GUITAR OUTPUT for its synth sound. The GUITAR OUTPUT produces only your
guitar’s dry, unprocessed sound.
2 Make sure that your sensitivity settings have been adjusted properly. Refer to “How Do I Optimize the GR-20’s
Sensitivity for My Pickup?” on Page 3 of this booklet, or “Adjusting the Input Sensitivity (GK SENS)” on Page
12 of the GR-20 Owner’s Manual.
3 Is your GK pickup switch set to “SYNTH?”
4 Check your GK cable—is it properly connected at both ends?
5 Is the volume of your amp, mixer, or PA turned up? Try connecting headphones to the GR-20’s L/PHONES
OUTPUT jack.
6 Is the GR-20’s Expression pedal in its proper toe-forward position?
7 Make sure the GR-20’s rear-panel LEVEL knob is set to its MAX position, and that the GK-3’s volume knob is
turned up.
1 Select a patch.
2 Edit the patch as desired to create a new patch of your own.
3 Press the WRITE button.
4 Turn the NUMBER/VALUE dial to select the memory location from 1-99 in which you want to store the
patch.
5 Press the WRITE button—as the GR-20 stores the patch, a blinking dot appears in the corner of the display.
Important!! Do not turn the power off while the GR-20 is storing you patch. Wait until the dot stops blinking before
powering down the GR-20.
