Thank you for viewing. This is the BOSS multi-effects processor "GT-1". It can be powered by batteries or AC adapter. I am selling it because I sold my guitar. Although there is no box, I will include the case that I used to carry it around. An AC adapter is also included. * There are small scratches on the main unit (see photos). * I will not respond to comments requesting excessive discounts. I will delete such comments, so please understand. #GT-1 #BOSS #boss #gt-1 #effects processor #guitar
