An effects pedal that combines the functions of overdrive and distortion. I used it about 10 years ago, but I'm selling it because I'm using a multi-effects unit. It has been stored in a shelf at home and I haven't confirmed its operation, but it will probably work. There is no box. Tape is attached to the back. Please consider it as junk and with no returns, refunds, or exchanges. - Model Name: OS-2 - Type: Overdrive/Distortion - Color: Yellow - Controls: Mix, Tone, Level, Distortion ※AC adapter is not included Thank you for viewing.
