This is an Over Drive pedal from Boo Instruments. It's an early model with the "Made in England" stamp. I liked the look of it and had it imported from England. It's a truly classic pedal, but with true bypass, so there's no sound quality degradation when it's not in use. It uses the JRC4558D op-amp chip, which was used in the vintage TS808. This is an effector that's hard to find these days. No claims and no returns accepted. Type...Electric Guitar Manufacturer...BOSS
