Amazing Acoustic Simulator for Electric Guitar!

How many times have you been onstage or in the studio with your electric guitar and wished that you'd brought an acoustic along? For musicians who travel light, hauling an extra guitar to the gig isn't always the most attractive option. Here's the solution: the BOSS AC-3 acoustic simulator! This new-generation compact pedal employs COSM modeling technology to transform any electric guitar into a variety of beautiful acoustic guitars.

BOSS AC-3 Acoustic Simulator at a Glance:

  • Advanced modeling for authentic acoustic guitar sounds

  • Fine-tune controls to shape the acoustic sound you want
  • Reverb included
  • Versatile output paths

Advanced modeling for authentic acoustic guitar sounds
BOSS's COSM Acoustic-Modeling technology is beautifully showcased in the small but powerful AC-3, which simulates an acoustic guitar much more precisely and realistically than previous technology allowed. Derived from BOSS's 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. Previous compact acoustic-guitar modeling-pedals were promising, but now the bar has been raised with AC-3.

Fine-tune controls to shape the acoustic sound you want
The AC-3 provides Top and Body controls which allow you to shape the characteristics of the four acoustic models. Create the perfect acoustic-guitar sound quickly and easily with simple knob twists.

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

Versatile output paths
Two sets of outputs are provided, allowing you to connect the AC-3 to a standard guitar amp, a direct input device such as a PA, or a recorder.

BOSS AC-3 Acoustic Simulator Features:

  • BOSS's most advanced acoustic-guitar modeling in a compact pedal

  • 4 simulation modes: Standard, Jumbo, Enhanced, and Piezo-equipped
  • Top and Body knobs for fine-tuning the virtual-body resonance
  • Built-in reverb, optimized for acoustic-guitar simulation
For authentic acoustic sound from your electric, get the BOSS AC-3!

No other as good as AC-3

In the matter of getting the unique and best sound out of guitar, there is one point in which hands need extra help. I have found AC-3 not just a practic pedal with 4 strong and seriously real acoustic modes. In addition, it's amazing the body and definition guitar can get from this box. I have learn that in the process to be a good guitar player is a must to find and decide which sound contributes to the music concept and style. If Playing demands some nice acoustic tone, BOSS AC-3 WILL NEVER FAIL.

Useful pedal

I found that this pedal works best with a full range PA speaker. Sounds better through a QSC K8 than a guitar amp. The built in reverb is great, With a little tweaking, it is a neat tool for gigs.

Interesting, versatile pedal

I decided to get one of these since recording acoustic guitar (and having it sound good!) is a real struggle and I figured this would be cheaper and easier than trying to buy a matched pair of microphones and set them up properly. It sounds pretty much how I expected it to, not a perfect emulation but it has an interesting sound of its own. I have been able to get a pretty decent acoustic sound, especially with the aid of a few VSTs. However, I have had the most fun just using it to alter the sound of my electric guitars - you can get some interesting glassy tones as well as a lot of warmth from the "body" setting, and the reverb adds a lot to the tone. It's a bit expensive for what you get, but once you experiment with it you can really use it for some interesting stuff.

Can't wait to try it on my new amp!

Okay so why have this pedal, when surely we all have acoustic guitars? Well there could be mic'ing issues, acoustic issues, all sorts of reasons. The bottom line is having this pedal does not remove all acoustic guitar playing and they are mutally inclusive. That being said, its really a gas (as our british fellows would say) to use my les paul black beauty or my fender strat and make it, in a sense, sound like a gibson hummingbird or so we'd hope so. Anyhow if you need an emulated sort of acoustic guitar effect, look NO FURTHER this IS IT. I am getting a new amp tomorrow so I can't wait to see how my 57 fender 2x12 reissue (hand wired baby!) sounds with my Black Beauty.

Well Pleased ....

I got into a mess with our church trio performances by having to do too much between songs.. switching between electric and acoustic guitars being an issue. So I thought to give this this pedal a try. I read a lot of reviews on the internet and you would do well to review them too. This unit WORKS. However you have to understand if you are playing acoustic-electric you are sitting on top of that sound hole in the guitar. This pedal is NOT going to sound like that! I have this pedal sounding pretty much exactly like my acoustic guitar would sound OUT OF THE SPEAKER when using the BOSS AD-3 pedal through my PA system. In other words, it worked for me in the context of my playing. I now no longer NEED to switch guitars between songs. But you really need to understand the limitations and also what influences your result ... your electric guitars PU's, using the neck PU and utilizing coil splitting (I am using an Epiphone ES339 Pro for this) and NOT humbucker. My band mates gave it a thumbs-up. If you are needing a 'real' acoustic for those 'special' songs, this IS NOT going to get that vibe. If you are wanting to get pretty much in the ballpark for a great majority of songs and not wanting to haul that acoustic around, etc. then definitely give this pedal a try!
