The BOSS AC-2 Acoustic Simulator is a compact effects pedal designed to change the sound of a standard electric guitar into that of an acoustic-electric guitar.
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
