Tri-Vibe Popping

[Droogie]

I'm having issues with two Tri-Vibe builds. One is a ChiBoy board, the other is a Fuzzdog. Both have switch pop due to DC on the output that I can't seem to track down; one uses relay bypass, one 3pdt. I also get popping when I change vibe modes. Anybody else encounter this with their builds?

Tried various resistors to ground on input and output that lowered the DC, but nothing totally stopped it.

What type of cap are you using for the output?
