And for that matter, what does replacing C2 with a diode accomplish? Why was C2 there originally and what's C1 for? Before I go replacing components in mine.
Still wanna try and true bypass this pedal too, I noticed delays even when the pedal was off with high gains infront of it, could be my heat damaged JRC4558 though, which will be replaced when I finally get some solder braid.
There are a few traces that AM cuts and jumpers to reroute the power to help better accommodate varying power supplies. The diode replaces C2 for polarity protection (as C2 was an arguably redundant cap in the power filtering circuit)
C34 is in the flip flop circuit. If it's bad, you get unreliable switching--so it's best to put in a good quality cap in there from the get-go to avoid any unpleasantness later on.
Swap out that 4558 for a TL072, it helped. The squeal was taken care of when I moved all the wiring to the far side of the board (just pushed it as I reassembled) away from the clock timer.
