Dual overdrive pedal, yellow. - Model Name: DUAL OverDrive SD-2 - Color: Yellow - Output Terminals: OUTPUT - Input Terminals: INPUT - Remote Terminals: REMOTE This is a dual model that allows for Crunch/Lead settings. The exterior has some minor scratches due to actual use. Operation has been confirmed. There are no issues with knobs, switches, or crackling. The rubber rings for the footswitch screws have been replaced with new ones. The unit only. I purchased this new approximately 30 years ago and used it for 2-3 years. After that, I switched to a different brand and didn't use it. I am selling it to organize my equipment. It's vintage, but I think it can still be used. Thank you for your consideration.
