Boss AC-3 Acoustic Simulator box

BOSS AC-3 Acoustic Simulator is a digital compact effects pedal designed to transform the sound of an electric guitar into an acoustic guitar tone using advanced COSM modeling technology.
It is widely used by gigging musicians to switch instantly between electric and acoustic tones without having to swap physical guitars on stage.

Key Features and Modes

The pedal provides distinct acoustic textures through four simulation modes paired with digital tone-shaping controls:

- Standard: Simulates a traditional, mellow acoustic guitar body style.
- Jumbo: Emulates a large-bodied, oversized acoustic guitar with deep bass resonance.
- Enhanced: Delivers a sharper, high-end attack designed to cut cleanly through a busy band mix.
- Piezo: Replicates the signature attack and crisp resonance of a roundback guitar equipped with a piezo pickup.
- Body & Top Knobs: Act as a two-band virtual EQ; the "Body" knob adjusts virtual-body resonance, while the "Top" knob fine-tunes upper harmonics and brightness.
- Built-in Reverb: Includes an integrated digital reverb optimized specifically for acoustic simulation to add warmth and environmental dept
