Update: I’m not sure how or why, but when I plugged in the pedal this morning (out of enclosure) the effect worked. Very dark tone, but at least it was a start. When I put the PCB into the top of the enclosure, it went back to my original problem of just bypass tone, whether the effect was engaged or not. Also, I am not hearing the relay click now with the PCB in the enclosure. Kind of weird.
I have checked all of my joints, and while some are a little ahem enthusiastically soldered, there don’t seem to be any unwanted solder bridges. It does occasionally make a noise when engaged, if I am not grounding the circuit, there is a high-pitched hum that pulses with the rate of the tremolo. Still no signal from the guitar though.
How would I check with my multimeter if there are shorts between the IC pins? I am using the insulation paper.I re-seated the microcontroller (there were some bent legs that I don’t think went all the way into the socket.) Now when I plug everything in I get straight bypassed signal when disengaged, and no signal when the effect is engaged. Is my signal being sent to ground because of the jumpers not being correctly bridged? How would I go about bridging that with wire if the pads at JP2 are essentially burned off?

One thing I noticed going over the relay and micro-controller is that I may have put the IC socket in backwards. I have the IC orientated correctly to the circuit (lined up the divots). Socket orientation has never mattered in other builds I’ve done. Could this cause an issue?
