Going through step 5 of the TG: There is NO continuity between input/output tips with bypass led OFF. With led ON, there is continuity between input tip and R1. There is NO continuity between output tip and vol. pot center lug. The relay clicks whenever bypass switch is pressed. R28 reads .45v. Everything is installed correctly and solder joints all look good. The pedal worked well for many months until this recent issue. It was never dropped or handled roughly. I’m just assuming it’s a component failure, but finding which one is certainly a challenge!
I hope this info helps.
Thanks again
