Boss AC-2 Acoustic Simulator

The Boss AC-2 Acoustic Simulator, released in 1997, was designed to transform the sound of an electric guitar into that of an acoustic guitar. As one of the first compact acoustic simulation pedals, it offered guitarists the flexibility to achieve acoustic tones without switching instruments. The AC-2 features four modes—Standard, Jumbo, Enhance, and Piezo—each simulating different acoustic guitar characteristics. It also includes controls for Level, Body (adjusting bass resonance), and Top (adjusting treble brilliance). Despite being discontinued and replaced by the more advanced AC-3 in the 2000s, the AC-2 remains a practical tool for live performances and quick tonal shifts.

Historical Development

• Design Philosophy: The AC-2 was created to provide electric guitarists with a simple way to emulate acoustic tones during live performances or recordings. While not a perfect substitute for a real acoustic guitar, it offered a convenient solution for players seeking versatility.
• Features: The pedal includes dual outputs (effected and direct), allowing users to route the acoustic simulation and unprocessed electric signals to separate amplifiers or effects chains.
• Discontinuation: The AC-2 was eventually replaced by the Boss AC-3, which introduced COSM modeling technology and additional features like built-in reverb.

Notable Players

• While specific high-profile users of the AC-2 are not widely documented, it has been praised by gigging musicians for its utility in live settings. Players often used it with Stratocasters or other single-coil-equipped guitars for optimal results.

Popular Settings

The AC-2's modes and controls allow for tailored acoustic emulation:

• Standard Mode: Body at 12:00, Top at 1:00, Level at max for a balanced dreadnought-style tone suitable for fingerpicking.
• Jumbo Mode: Body at 2:00, Top at 11:00 for a richer bass response ideal for strumming chords.
• Enhance Mode: Body at noon, Top at 3:00 for bright, cutting tones that stand out in band mixes.
• Piezo Mode: Body at 10:00, Top at 2:00 for a compressed, electric-acoustic sound.

Legacy

The Boss AC-2 Acoustic Simulator remains a unique pedal in Boss's history. While it received mixed reviews due to its limitations in fully replicating acoustic tones, it provided a practical solution for live performers needing quick access to acoustic-like sounds. Its simplicity and affordability have made it a nostalgic favorite among players who value its straightforward approach to tone shaping.
