Description
Leave the acoustic at home. The Boss AC-3 Acoustic Simulator uses COSM modeling—the same tech behind the flagship AD-8—to reshape your electric guitar’s signal into four distinct acoustic voices: Standard, Jumbo, Enhanced, and a Piezo-equipped mode built for that bright, direct piezo edge that cuts through a busy mix. Each mode tracks your picking dynamics and note articulation closely enough to hold up in a live set, not just a bedroom demo.
Dial in the character with Top and Body knobs, which shape the virtual soundboard resonance and tonal balance independently. Push Top up for sparkle and string definition, or lean into Body for a rounder, chestier low end—useful whether you’re chasing a fingerstyle jumbo tone or a slimmer parlor-guitar feel.
Baked-in digital reverb, tuned specifically for the acoustic models, adds room depth without needing a separate ambience pedal on your board. Because it’s voiced for this pedal’s simulations rather than generic reverb, it sits naturally instead of washing out the acoustic character.
Dual outputs let the AC-3 feed a standard guitar amp and a direct line simultaneously—handy for sending a clean acoustic signal to a PA or recorder while still monitoring through your rig.
