This is really embarrassing. I was in my DOD FX90 delay attempting to correct the switch problem. Two of the flying leads to the PCB broke. They are both green. I found a photo online to get the correct terminals for each wire. I blew it. My pedal was lying in the opposite direction of the photo. I got them backwards.
One wire goes to the output jack, from the PCB. The other comes from the footswitch to the PCB.
Did I fry the chip?
Prolly not, switch them round.
Thank you! I'll let you know how it goes.
Pedal is working fine. I was told the switch problem could be corrected by backing the nuts on the Allen screws off a little bit, but that wasn't the case. The switch is bad.
