Question for you guys.
I had a dual looper pedal built for me (A/B between two sets of loops, I use one for my buffered pedals, and one for a fuzz that doesn't play well with them), and when I'm in the "buffered pedal" loop, I have bad bleedhrough "hum" noise coming from the "bypassed" fuzz loop. If I toggle that fuzz pedal off, it goes away, but also defeats the purpose of the pedal (just hitting one button to swap between the buffered pedal and onto that fuzz). I was poking around and noticed that all the jacks' grounds are wired together, going to the center hub on the 3PDT switch, but also wired to the PS negative jack as well. I checked all the other connections and nothing's loose or grounding out on its own.
Is it potentially the problem that the PS/jacks/LEDs are all sharing a common ground? Would I be better off separating the jacks' grounds and the LED/switch/PS ground?
Here's a pic. You can't really see where the traces are going, but get a general layout understanding.
