Hi guys,

Someone just gave me an RE-20 echo pedal to fix. Power LED comes on but the pedal is dead. Switching LEDs don't operate either. There's nothing obvious inside that looks to be a problem - no burning anywhere, no fluid residue. I going to check the crystal right now but I don't have any info at all on this pedal.

Does anyone have a schematic for this unit? I can't find one anywhere!

So, a little further forward... the 3.3 volt line is missing... therefore no supply to the logic. Still need some schematics though!
