Used BOSS AD2 Acoustic Preamp Guitar Preamp

Used BOSS AD-2 Acoustic Preamp in good condition, delivering studio-style acoustic tone in a compact, road-ready stompbox. Featuring Acoustic Resonance for natural body and depth, plus ambience, 2-band EQ, and notch control to help tame feedback onstage. Simple, stage-friendly layout with standard 1/4" input/output and 9V battery or optional AC adapter power. A great choice for warming up piezo pickups and dialing in a polished live sound.
