Acknowledging the loyalty and love guitarists have for that original OC-2 sound, the BOSS OC-3 offers the user the ability to blend up to three different sounds. A versatile pedal, the OC-3 features separate inputs for both guitar and bass, while retaining the original OC-2 mode, capable of producing notes one and two octaves down.

The new Drive mode the OC-3 boasts adds distortion to octave notes for a fat, aggressive tone, while the true Polyphonic Octave effect is adjustable, affording the musician to play within a specific note range.
