I've been trying to troubleshoot this one to no avail. I'm getting a strong dry signal up to R4. At R20 the volume drops. It's faint at the mix pot. After the mix it's gone - no audio (wet or dry) is passing.
I made a questionable choice when I drilled the enclosure, totally forgetting that the shaft on the 1P8T isn't very tall. I wanted side jacks, but they're not low enough to let the board sit nicely with 1P8T protruding enough to be useable. You can see my janky extensions but they don't sound like they're causing issues - I can hear a wet signal with the distinct effects. I had to mutilate the pots a bit to get them to fit (they were PCB-mount pots that got chopped down). I could see that having caused a problem. I pulled the board out of the enclosure just in case something was grounding. This made no difference when I was testing.
I'm currently trying to figure out where to begin replacing components. I reflowed the solder joints on the B10k pot. I replaced R20 (it looks like I need to touch up the solder on one side). I'm going to try a different B10k pot. Any other thoughts? Am I totally missing something that's obvious in the pictures?
There's a bypass signal, the FV-1 has an output signal at Pin28, the ctrl pots seem to be working, the 1P8T seems to be working.
