Used Boss AC2 Acoustic Simulator

Used, very good condition, velcro on bottom.  No box or manual.  From Boss:

• 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
