Used MXR MX-101 Block Phase 90 1979

For sale we have a Phase 90 from 1979-1980 (based on the 1979 pot date code). 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 does not have a 9V power jack (battery only).
