AC-3 Acoustic Simulator

The AC-3 Acoustic Simulator updated the AC-2 with improved body simulation algorithms and added a piezo input for players who already have piezo-equipped guitars. Released as the second generation of Boss's acoustic simulation.

Four acoustic body types with improved algorithms over the AC-2. A dedicated piezo input enables blending piezo pickup signal with the simulated acoustic tone. Built-in reverb adds natural ambience. The improved processing produces more convincing acoustic simulation than the first generation.

Body, Top, Level, and Reverb controls. Expression pedal support for real-time parameter adjustment. The piezo input and improved algorithms make the AC-3 significantly more versatile than the AC-2.

For electric players who need acoustic tones on stage or in the studio. The piezo input option bridges the gap between pure simulation and hybrid electric/acoustic signal blending.
