This is a modified BOSS ODB-3 by Weed. I'm selling it to declutter. It's a modified version of the BOSS overdrive pedal designed for bass, addressing the shortcomings, so I can't go back to a regular ODB-3. If you're feeling unsatisfied with your usual distortion, please give it a try. I've used it many times in rehearsals and live performances, and there are no issues with its operation. Velcro is attached to the back. Please note that there is some paint chipping (see photo 3).
