This is the MXR overdrive, the "SUGAR DRIVE." I purchased it 2-3 years ago and used it at home and in the studio. I'm selling it to clear out some gear. It's easy to use as both a booster and a main distortion, and it's a valuable addition to any pedalboard. I've placed it before various distortion pedals, but I preferred it before the FRIEDMAN BE-OD. It functions perfectly. There is some discoloration on the back due to the effects pedalboard tape. Other than that, it shows signs of use, but there are no major scratches or stains. I will carefully package and ship it. I look forward to your purchase if you understand that this is a used item.
