When I first heard about the acoustic simulation pedals I was a little bit leery of how good the simulation would sound. Then I heard Slash from Velvet Revolver and Guns N Roses use one live in some gig I saw on tv. To my pleasant surprise it actually sounded pretty good. He was playing a Gibson Les Paul and those guitars can be very girthy and robust on tone and to get a guitar like that to sound like a wood hollow body it a big feat of strength.

Delivers amazing acoustic guitar simulation using a standard electric guitar
Four acoustic "modes" give guitarists distinct acoustic sounds: "Standard," "Jumbo," "Enhanced" and "Piezo"
"Top" knob adjusts the effect's overall brilliance and harmonics
"Body" adjusts the resonance of the simulated acoustic guitar body
Individual outputs for effected and un-effected sound allow for the use of separate signal chains and amplifiers

This pedal does work and works very well. Let me be very clear, it will not replace the tone of a real acoustic guitar no matter how trashy a cheap acoustic guitar sounds. If you have a cheap acoustic guitar, that guitar will sound better and more natural than an electric guitar using this pedal. However, this is great for a gigging musician that has an acoustic part in a sound and needs to switch quickly to an electric part of a song.

The tone of this pedal is decent for the playing who doesn't want to carry an acoustic guitar to a gig and only use it for minimal parts. You can just bring this pedal and your favorite electric guitar and have that acoustic sound quickly and easily for live uses.


I would not recommend this pedal as a replacement for an acoustic guitar in a recording session. This pedal will not get the hollow tone or organic feeling of a real acoustic guitar.

These pedals have now been replaced with the AC-3 which is a little bit better because it has reverb in the pedal and that is the only difference.
