Dude thanks so much for taking the time to draw this up, it’s super helpful. Will spend a bit of time comparing it to the schematic to rap my head around working it out myself next time.View attachment 94445
3PDT is your bypass stomper.
DPDT can be a 3PDT if you want to add an LED indicator to that, too.
While you could pull the FEEDBACK pot's lug-3 feed from the output jack itself or the 3PDT's output, I wouldn't recommend it — the great thing about the way Monsieur Bones implemented the switching is that if you bump the pot by accident or for whatever reason(s) the seagulls go full Hitchcockian on you, hitting the bypass will kill the gulls' screams.
