    Advanced Modeling

    BOSS’s COSM Acoustic-Modeling technology is beautifully showcased in this small but powerful pedal, which simulates an acoustic guitar much more precisely and realistically than previous technology allowed. Derived from BOSS top-of-the-line AD-8, the AC-3 simulates the sound of an acoustic guitar with incredible precision. Four simulation modes are provided: Standard, Jumbo, Enhanced, and Piezo-equipped; the latter supplies that famous “cut through the mix” direct piezo sound.

    Fine Control

    Previous compact acoustic-guitar modeling-pedals were promising, but now the bar has been raised with AC-3.

    Top and Body controls are provided for shaping the characteristics of the four acoustic models. Create the perfect acoustic-guitar sound quickly and easily with simple knob twists.

    BOSS AC-3BOSS AC-3

    Versatile Output Paths and Reverb Included

    Two sets of outputs are provided for connecting the AC-3 to a standard guitar amp and to a direct input device such as a PA, recorder.

    Add depth and sweetness to the sound with the AC-3’s built in digital reverb. It’s like getting two pedals in one!

      You really didn't think it was going to sound like an acoustic guitar for real did you? This is a "simulator" pedal. This gives your Stratocaster a more analog like tone through an amp - if you will. It's another great effect pedal by Boss to add to your collection. Obviously so many more conditions like what kind of guitar, what pick ups (it's better on single coil) what are your settings etc. to get to your sound. If you really knew your amp and guitar and technique, you wouldn't even need it. But I just kick it on when I want it.

      I mean do disrespect. I love Boss pedals. I put this in my rig and it just didn’t do it for me. I could get deeper and discuss expectations but, IMO, there’s just no substitute for an acoustic.

      Many negative reviews on this. I quite like it. It sounds more like an acoustic than I expected, especially based on those review. Add a digital delay and you get the echo you would expect from a hollow body acoustic. I'm running this through the clean channel of the amp and the middle pickup of a Stratocaster. This gives the best sound for the items I have. There is a little bit of background noise from the thing but it is not bad enough for me to complain about it. A noise gate does silence it while not being actively played.

      When Keith Richards used a Fuzz pedal on Satisfaction, he was attempting to emulate a trumpet like timbre. Did it sound exactly like a high end Trumpet? Of course not. If you are tone chaser and/or a tone snob, you need to look elsewhere. If you have the expectation of sounding like a high end quality acoustic guitar rig with this pedal, you have unrealistic expectations. What does the pedal do well? If you are willing to work with an Acoustic "like" pedal, it will add some nice clean tones to your rig. I can dial in some decent tones on my Fender Strat with noiseless single coil pickups. I find the Enhanced and Piezo modes less than desirable. I struggle to dial in something I am happy with in those modes. However, Standard and Jumbo modes I really like. I find I have to get rid of the Spring reverb on my Hot Rod Deluxe. Using the Reverb on the pedal helps in my opinion. I use the middle pickup on my Strat. Playing chords sound somewhat "okay". This is the trickiest to dial in. But, it is doable. Finger picking sounds pretty good in my opinion. Also, lead tones are fairly easy to dial in as well. Some people have complained about a metallic and or tin like sound. You just have to remember to use the tone on your guitar as well as your pedal. You can totally take those highs out. I wouldn't recommend using Humbuckers. The sound is too beefy for me. However, I am sure that there are people out there that could make it work. Bottom line is, if you want to get a quick acoustic like jam going, this can be fun. So long as you accept it is Simulator.

      Maybe I was expecting too much, but after working with it for a week, I ended up returning. My ES-335 probably had the best "acoustic" tone but it was still lacking and unnatural. I do think it would work OK if you put time in setting up both the pedal, an EQ box, and the amplifier. I was running through a Fishman Loudbox mini. Again, it's nice if you have some acoustic stuff you need to do during your set, but it doesn't replace an acoustic guitar IMO

      The Boss AC-3 Acoustic Simulator is exactly what it is advertised. I am a long time acoustic guitarist (Taylor 810ce, with beautiful bass tones). Because of some physical challenges, I have recently acquired an electic guitar primarily for the ease of play, but also because I wanted to expand my musical options as a guitarist. Basically, am having a really hard time making the transition in sound produced.

      I am playing a Fender American Standard Strat through a Fender Blues Junior amp. The Strat is about as "electric" as it get and I've dealt with the loss of "bass" tone with thte use of an Equilizer. The Boss AC-3 has helped me achieve a really nice acoustic simulation, which has made playing more enjoyable for me. I do have some difficulty with the "Top" end control adjustment being very sensitive, causing an annoying, unwanted hiss and distortion, but work most of it out with turning it down to a minimal position and compensating the drop in trebles with twiking my equilizer. I'm still experimenting and twiking for "my" sound, but thus far I believe that the Boss AC-3 is meeting my expectations and is central to my set up.

      Disappointed with this pedal effects. Can't have a clean sound whatever connection and isolation of power supply I do. Static noise is very loud that greatly affect your tone and sound. Boss is usually good in this thing, they should discontinue this product. I returned mine and now looking for a different acoustic simulator. Avoid this product.

      as Acoustic simulator, meh ain't an acoustic
      also this does not play well with humbuckers (in acoustic mode)
      so in regards to simulating acoustic, single coil pickups need apply only! You have been warned!

      on the positive side
      on both single and coil and humbuckers
      This makes for a fantastic reverb pedal, thanks to dragging bass in to the mix
      this set to reverb at 10oclock and set to enhance mode + a decent delay = happy times
      EDIT: Found this, set to standard, rev @ 10'oclock, body & top 2 o'clock, with signal chain of compressor then a DS1 overdrive = driven/overdriven cracked speaker tones <3

      Still trying to get an acoustic sound from this pedal. It is not working with my Orange amp and Ibanez metal series guitar. I get only clean sound. I am unable to get even a little bit of acoustic sound from it. Settings are too complicated. May be it will work for other guitars and amps. If you have an Ibanez metal series think twice before you buy it. However I had seen numerous reviews on the YouTube where I heard good acoustic sound from this pedal. So if your guitar is hardcore metal type don't expect this pedal to work for you. Amazon service is good. The seller is very good. He was the first seller who did not take away the original alkaline battery and send a cheap one. All others did, when I bought other pedals.
