The way I have it wired (which is how it originally was when it used to work) is how the guy has it in the link to the video I posted. I understand there are multiple ways to wire a 3PDT switch for true-bypass, right? Anyway, I’ll take some pictures tonight and post them. Maybe somebody can say, “No, dummy! THERE’S where you screwed up.”
Thanks again for all the help, guys.

I accidentally broke one of the pots and decided to upgrade all of them.
When I wired everything up, it didn’t work, so I tried again.
Now I only get a signal when the pedal is bypassed. When I engage it,
the sound is cut and the LED doesn’t light.
