Used MXR MX-104 Block Distortion + 1981

For sale we have a Distortion + from 1981. The pedal functions flawlessly with no issues. The foam inside these pedals melts and turns into a gloopy mess. We removed most of the foam and replaced it with a thin sheet of easily removable plastic over the PCB to prevent ground-out issues. The pedal has some stickers by the power jack
