And for the truly derp moment, I do this myself when swapping pedals around, did you have the input and output wired and oriented correctly? I've lost track when I've put outputs from box to box together >< only other thing I could guess at is those 2 resistors needing a little space, flashover is a thing, I worked at a place the breakers on some equipment had a 24 INCH/60cm arc/spark.
