The first bass overdrive pedal in the BOSS Compact Effects range, the ODB-3 can deliver smaller, more concise sounds to the huge overdrive fans of the heavier genres will know and love, with ease. With the pedal's Balance control, mixing bass and effect signals to achieve the pressure of the bass' original sound, even in heavy distortion, just got easier. The onboard two-band equalizer (low/high) is another feature of the ODB-3 that makes it more than just a normal overdrive pedal.
