AD-3: Acoustic Instrument Processor
Developed for stage and studio use, the AD-3 gives acoustic-electric guitarists a warmer, richer sound thanks to its Tone shaping controls specially tailored for acoustic-electric guitars, high-quality Reverb and chorus, as well as a built-in Feedback eliminator. Quite simply, this compact pedal is an acoustic musician’s best friend.
