I bought this new many years ago and honestly haven't used it much. I am trying to cut down my pedal inventory so am listing some items I am not using. This is in excellent condition and works great. No box is included. Only trades considered would be a noise/glitch weird pedal like Bitquest etc... Thanks for looking and feel free to ask questions. More pictures can be provided. Shipping included in 48 states. Paypal fine. The Boss OC-3 Super Octave is an octave pedal that contains modes for the original OC-2, which allows for one and two lower octave notes, as well as a Polyphonic mode and Drive mode. Use the Direct, Octave 1, and Octave 2 knobs to control your sound. The OC-3 has been used by artists like The Black Keys, Van Halen, and Tony Iommi.
