"A or B/A—>B" Loop Switcher wiring question

[mdcmdcmdc]

Hi folks,

I'm trying to sort out a particular switching arrangement and I can't seem to find an example of the thing I'm looking for. It's not particularly esoteric, so I imagine I'm just using the wrong search terms... if anyone could point me in the right direction I'd be appreciative!

I'm looking for the following:
- mono I/O
- 2 FX loops
- 1 footswitch to control A or B (ping pong/flip flop/whatever you want to call it)
- 1 footswitch to turn on both A and B (in series, A into B)
- 3x indicator LEDs
- no need for master bypass, one of A, B, or A—>B is always on

Thank you in advance!

quick MS Paint work for you

Thanks so much!
I'm trying to parse this diagram out but it's not clicking completely...

Red boxes are SW1A and SW1B?
Blue are SW2A and SW2B?
Four circles at the top are 1-snd, 2-snd, 1-rtn, 2-rtn?

hope this helps

Red boxes are SW1A and SW1B?
Blue are SW2A and SW2B?

yes, correct

ow, and i assumed you could figure out the LEDs if youre using 3pdt switches

cheers

Ahhhh that makes a lot more sense now. I was reading it L-R and couldn't wrap my head around it.

Thanks again for the help!

Coming back to this after a few days, I think there's still combination in your suggestion that breaks the system (although it's entirely likely that I'm reading it wrong). Probably for my particular use-case I can simplify it by having the output of Loop B always connected to output, then it's pretty easy to make the rest work with a 3pdt and a dpdt.

edit - I spoke to soon, that doesn't actually work either... still hacking away...

This maybe? With a 4PDT and a 3PDT?
