This is the BOSS GT-1, a classic multi-effects processor. It's a recommended model for beginners making their multi-effects debut. A BOSS genuine adapter is also included in this set. It will be shipped in the original box it came in! The condition is quite good, but there is a small, inconspicuous scratch on the side (as seen in photo 3), and one of the non-slip pads on the back (the side not visible during use) has come off, so a replacement pad has been attached. Also, the box for the genuine adapter has a tear on the back, so it will be shipped with it, but please consider it for authentication purposes only. There are no issues with its use, and considering the above points, I am selling it below the market price!
