I found a mistake in my drawing. I performed a ninja edit. look again at the pic I posted which is now corrected.

those are net names. so in theory, anything with the same name is connected by a conductor. you can call them wires.

I don't see how it's impossible to mute B. Eatyourguitar, nice; I didn't consider going parallel with the third switch.

In B always goes to Out B no matter what the position of the first momentary footswitch is in the drawing.

Re: AB Box with a twist [not working...]
oh ya my bad. it is ok i think. im not trying to be smart.
the3rd momentary in parallel is the key though for sure.
you can do it another way too, i will scan it later.

Well I'll have to try and wire it to figure out how it works I guess. The parallel thing is new to me.

I don't know how you came to that conclusion. my design is working and peer reviewed

Re: AB Box with a twist [not working...]
It's not going to be the first time I get it wrong and it won't be the last either... It took me a million years but I get the left side and yes of course it works! I'll have to see how I wire the parallel one and I'm there I guess. Thanks a lot!

sig worthy.haha.
but ya his design is fine.
here is basically the same thing drawn more schematicall so maybe it will be easier for you to 'see' how it works.
momentary 1 is the a->a, b->b momentary.

Thank you all! I'll do the mod this WE and will get back in touch if I encounter problems, though I think it'll be straightforward.
