Boss · pedal
The Boss AD-2 Acoustic Preamp is a dedicated preamp pedal for acoustic-electric guitars, offering tone-shaping designed specifically for piezo and other acoustic pickup types rather than adapted electric guitar circuitry. It provides EQ control, a boost function, and anti-feedback processing aimed at giving acoustic performers cleaner, more natural amplified tone on stage.
