Thanks for the tips, Brach. I reflowed all the connections as you recommended. Still, no luck. I also checked all the voltages, and there were two weird readings. I’m only getting .42v at R28, and pin 5 of U2 is only reading 2.4v. Every other reading was normal. BTW, this isn’t the first issue I’ve had. In tracking down a previous issue, I very well could have overheated a component or two. I like to think I can solder decently, but I haven’t worked with printed boards much until this project. IMHO, the design of the pedal and the quality of the components is excellent. I loved the pedal when I had it working, but I’m starting to feel like my board is a lost cause because of all the abuse I’ve put it through. If I can’t track down the issue, would it be possible to get a fresh board and set of caps, resistors, etc.?
Thanks again,
Peter
