Also, looking at it again, the link between the two "from B" connections is redundant... or keep the link and get rid of one of the wires. Sorry to hijack!!

That's what I assumed - maybe gig rig call it "ping pong"?

I mean relays are probably easier at that point, but it was a fun logic puzzle.

I tried to diagram it out a few months ago and I think I got it correct, but I'm 90% sure you can do flip-flop A or B / A into B with two switches. I didn't actually build it, but if it does work It'd be easy enough add bypass around that on a third switch.

Maybe just get an ES-8

I think that should work for a flip-flop a/b with global on/off. Black is ground - I'd star ground it just in case there are loops somewhere.

Are you specifically looking for a relay-based thing, or do you just want an A/B w/ on/off? That's pretty straightforward with mechanical switches.

Using an electrolytic (like the 220uF) and an MLCC (like the 100nF) in the power filtering is pretty common, as they're filtering different things. Why there are multiple 220uFs in the power filtering section is beyond me, but one thought might be that they make sense on the original PCB...

An easier way to get a similar outcome might be to bias the circuit 'properly' via the trimpots and then install a simple voltage starve pot; then you'd be adjusting voltage across all of the JFETs at the same time rather than having 2 or 3 external bias trims. It might sound cool in some...

Maybe start here if you haven't already? http://tagboardeffects.blogspot.com/2012/09/vero-layout-guide.html

I'd remove the LED from the PCB; wire power and ground from the DC jack to the PCB as usual; omit the LED connection to the footswitch from the PCB; then wire everything else as shown in the diagram. If you're not familiar with vero builds this would be a pretty easy one to start with.

Maybe this is obvious but did you by any chance buy DC jacks with metal sleeves? Those will short out against the enclosure.

This worked for me when nothing else would. It's super simple... https://forum.pedalpcb.com/threads/voodoolabs-optical-bypass.11329/

It's an LPF.
