This is the Providence SOV-1 overdrive pedal. This particular unit is an ultra-rare early model with Line IN/OUT jacks, the same specification used by Eriko Hashimoto from the band Chatmonchy to the present day. It comes complete with the original box, instruction manual, and unused rubber feet, making it a great collector's item. The pedal itself is in excellent condition, with only a few small chips and light scratches on the exterior.
