I’m the original owner of this pedal, and it’s been in my storage locker for many years. It is in excellent condition (although the box is only fair condition), and the only thing that does not make it mint is a slight tear at the top of the “O” ring (see photo). There is no corrosion, no discoloration, and even the rubber pad looks new. And check the bottom – no “floor marks.” It includes the original papers! Inside number is 8100. I even have the original BOSS battery if you’re a collector.
