Something you don't see every day. Very usable, but also very collectable. This was acquired out of a private collection and is the 50,000th BG-2 to come off the production line. The (hard to read) 1974 date code is on the inductor. The original pot was (as was common with there) very scratchy, so replaced that with a Joe Gagan pot specifically designed for the BG-2 (which works in reverse when compared to a Crybaby pot). A few new wires and a new battery snap were added previously. Sounds wonderful - rich wah sweep which I calibrated to the sweep spot. Also functions as a volume pedal when the wah is off. Volume doesn't go to zero (it wasn't designed to), but has a nice sweep so can be great for swells. Full volume is toe-down. Even better, this comes with its original box, which has the (faded) 50K production number on it as well. Sweet!
