MXR Carbon Copy ILOVEDUST (Limited Edition). There are signs of use and scratches on the exterior, but it works well. The switch, knobs, and input/output have all been confirmed to be working without any problems. The sound is the same as the standard version, providing a warm, analog delay. Please refrain from purchasing if you are sensitive to the condition, as this is a used item. This is an auction for the main unit only.
