Finally figured it out! My new multimeter with a transistor tester on it just came in and I pulled the OC71 to find out it was DOA. Had a spare Russian unmarked PNP ge transistor from a Tonebender build. Tossed it in and success!!! The hFe of the Russian transistor is around 95 so it’s a little...

The trimmers are bass and treble controls for the second gain stage. I will check to see if there is power to the IC.

No they aren’t connected but there is a little black paint missing between them. Think that would affect anything?

Okay I’m stuck now. I built this Duocast and cannot get signal out of it. The bypass works, LEDs come on, but once pedal is turned on, it cuts the full signal. I’ve built several PCBs from PedalPCB and first one I’m stuck on. Things I’ve tried already, checked the pin outs on the OC71, flipped...
