BOSS DS-1 Distortion Pedal, 50th Anniversary Model. I'm selling this because it's no longer needed due to downsizing my pedalboard. It's been used quite a bit, so there are scratches all over the surface from being stepped on. Please refrain from purchasing if you are concerned about this. - Model Name: DS-1 - Brand: BOSS - Type: Distortion - Special Edition: 50th Anniversary Model - Controls: Tone, Level, Distortion - Input/Output Terminals: INPUT, OUTPUT Thank you for looking.
