Boss AC-3
Boss · pedal
The Boss AC-3 Acoustic Simulator is a digital processing pedal that simulates the tonal characteristics of acoustic guitars from a standard electric guitar signal. Four Body settings model different acoustic body types ranging from parlor-size to jumbo, each with distinctive resonance, brightness, and frequency profiles. A Chorus control adds the depth and shimmer associated with acoustic pickup systems and piezo preamps. A Top control adjusts the high-frequency presence of the simulated acoustic. Useful for electric guitarists needing acoustic textures in a live rig without carrying a separate acoustic guitar.
