Friedman Sir-Compre. This pedal is in excellent, like-new condition with very few cratches or nicks. It needed a new volume potentiometer, but is working like new again. As is with most compressor pedals (and Friedman pedals), I'd highly recommend using this with a gate or similar divice. This listing is for the box, pedal and paperwork. This pedal uses an external 18V center-negative power supply only.
