Boss ME50 REPAIR

I needed to repair my boss ME50 affects pedal. It was making program changes spontaneously on its own I needed to repair the potentiometers, which necessitated taking them out opening them up and cleaning them.
I only demonstrate one of them, but all should be done.

That problem arises a lot with those types of pots. I think they’re Alpha pots (BanzaiMusic carries them), and I’ve had to do exactly what you did at times. Simple problem, but a hell of a lot of time and fiddling to get the thing out of the enclosure and back again. Thanks for the video 👍

It's a bit of fun opening up and discovering how well made these parts actually are. Time takes its toll on them in the form of dirt and oxidation, but the repair and cleaning, while time consuming, can be done and is useful when dealing with parts not easily sourced.

My issue with the Rotary Encoders is, when i turn the knob to the next position the effect will not change or to a different/false one. It started on the Delay section but spread like a virus over to most of the encoder switches... i really want to replace the pots/ fix the ME but couldnt find the exact right replacement pots... can anybody help here?

Same problem here. I can't find replacement pots anywhere.
