BOSS AD-3 Acoustic Instrument Processor


Sold out.


Developed specifically for live performance, the AD-3 delivers a warmer, richer sound through precise impedance matching, built-in high-quality tonal controls, reverb and chorus, and an automatic feedback eliminator.

A Bi-Stereo Chorus with split-frequency processing (low and high) delivers a natural, smooth chorus effect optimized for acoustic guitar. The AD-3’s high-quality reverb exhibits a clear, deep effect specially tuned for acoustic guitar. Special Bottom and Top controls provide variable tonal shaping to eliminate “dry” sound from piezo pickups, while letting you add rich, resonant lows and brilliant highs at will.
