The Boss AD-8 Acoustic Guitar Effects Pedal uses COSM modeling technology to transform the piezo pickup sound of an ordinary acoustic into the tones taken from 6 high-end acoustic guitars. It also simulates the warm sound created by miking the guitar's neck and body—a world's first! Body and String Enhance controls simulate warm, miked acoustic sounds. Includes high-quality reverb tailored for acoustic guitar, 4-band EQ, anti-feedback circuit, a chromatic tuner with mute, and quick pedal-based operation. The Boss AD-8 has preset memory locations for switching acoustic sounds instantly. Balanced XLR outputs allow direct connection to PA systems.
