BOSS Over Drive OD-1 Purchased around 1980. I am selling it to organize my equipment. I checked the sound for this listing, and the effect still works without any problems. There is no rust on the battery contacts. There is some scratchiness in the LEVEL and OVER DRIVE adjustment knobs. This is an old item, approximately 45 years old, so I would like to sell it to someone who understands the current condition and accepts it as a used item. Thank you.
