Thank you for viewing. This is a listing for the BOSS GT-1 multi-effects processor unit. It has been used about 5 times and only at home, so I think it's in pretty good condition. I find it more convenient to practice guitar on a PC, so I don't have a chance to use it, and I'm listing it. Operation has been confirmed.
