ABY True Bypass - Two Effects - My brain hurts

[jmasciswannabe]

Anytime I start figuring out crazy switching stuff I feel like my brain implodes. It's not particularly easy to search for on the forum either. Hoping someone can point me to where this has been discussed. Here is the setup. Two effects (A/B) in same box with in and outs. Master true bypass switch. A toggle that selects (A/B) (A/Both) or (B/Both) and a footswitch that switches whatever the toggle has selected. When A or B is selected the other is bypassed. Is this do-able without relays?

I can't figure out what do you exactly want.

A or B toggle switch + master bypass switch, or something more complicated?

I think this part would be rought to figure out without relays, or at least 4PDT switches:

When A or B is selected the other is bypassed.

You will likely need relays and a microcontroller. Another option is to put the switches close together.

That's what I was thinking. At first I was just like, no problem, I'll do an ABY box with a master bypass, but did not take into consideration that the A or B is disconnected, not bypassed. I also though of putting them close together to be able to get both at once. In the long run I think the individual bypasses and a master bypass will have to be settled for.

Can't blame you. It's a little rough without seeing a layout visually. It's more complicated because a toggle selector switch would assign a footswitch to switch between A/B (while the other bypassed) - A/Both (while the other bypassed)  - B/Both (while the other bypassed.) The outs are running to two different effect chains with different amps.

I hate switching. I can offer you "Whole box on or bypassed" with 1 switch, and within the box,  "A or B" via another footswitch.  For that matter, "A into B" like a dist. into a booster or vice versa, "B into A" by toggle (suppose foot sw. could be done)   That's as far as I ever go!  My sympathies.
Even doing that would take me a bit to work out/find the info on my computer!

I'm the type that would rather build 2 boosters, put 1 before a dist, and one after, and just use what I feel like at the time - I think it's much easier and if something went wrong in the more complicated box, man, that could suck.

Sorry, I finally vaguely understood your post #3 reply, so my chicken scratch drawing wasn't relevant, and thus deleted.

Am I now more correct in guessing that "A/Both" and "B/Both" means that in each case, the selected effect is routed to both outputs, and in "A/B", each effect, A and B, get sent to their own separate outputs? That would definitely be beyond my little grey cells. It might be possible to use a 4PDT footswitch for the master bypass, but I cannot for the life of me figure out how to preset the configurations...

the selected effect is routed to both outputs

There's no mention of multiple outputs.

The function toggle is what makes it very hard to implement without relays.
Cornerstone used a microcontroller in the Gladio, STM32 but any jellybean 50 cent uC will do. It can even be done with discrete logic but why bother?
I would also opt for multiplexers instead of relays since you can still have master true bypass if you want it.

OP said "the outs are running to two different effect chains with different amps," which is why I drew the conclusion I did. But I'm sure I still don't understand what OP wants to do...
