BOSS is pleased to offer another ÒAuthentic BOSSÓ Compact Pedal; the AC-3. How many times have you been onstage or in the studio with your electric guitar, and wished that youÕd brought an acoustic along? For musicians who travel light, hauling an extra guitar to the gig isnÕt always the most attractive option. BOSS AC-3 to the rescue! This new-generation compact pedal employs COSM modeling technology to transform any electric guitar into a variety of beautiful acoustic guitars.
