Amp-Like Channel Switching for Pedals

[Dirty_Boogie]

Here’s my concept (probably not that original)… I’ve built 3 Victory V1 pedals that I really like. I’d like to emulate the channel switching of a 3-channel amp - P1 (clean); P2 (crunch); P3 (lead). Like the channel switching on an amp, I want 3 foot switches, and whichever one I stomp on, it becomes active, and the other two are bypassed.

I’m guessing this is some sort of looper configuration, but I’m not finding a schematic. Anyone have one they can point me to?

Thanks!

Possibly more complicated than you wanted, but the PPCB relay board has a channel switching configuration: https://www.pedalpcb.com/product/relaybypass/

This is great - thanks Robert! So, with 3 effects in "Channel switching" mode, would I wire it up like this? (I assume I'll need 3 Relay Bypass Modules):

 

[Robert]

Yep, exactly.

In the event that you want one of the effects to be excluded from the channel switching you just don't connect the CTRL wire to that module.

(For example, a dual channel drive with a boost where you want the boost to stay active regardless of which drive channel is active.)

Oooo this has me thinking: is it feasible to attach the control port to the ring of a TRS connector and not necessarily have them all in the same box?

Update: It would need to gracefully fall back to standard mode if a TS plug was inserted. I’m thinking this won’t work since any TS plug would short all of the control ports to ground.

That's got me thinking, too!

You could jam a toggle in between the control wires of the boards to toggle on/off the radio-button capability.

What if you use those fancy 9-Pin switching jacks? All audio is routed as per normal with the first switch handling whether or not something's in the loop (obviously I'm thinking loop-switcher rather than specific circuits in a combo pedal), and the 2nd switch of the jack handles the Control Wire feed...

From this thread:

It'll take me a while to wrap my brain around this, as to whether it's feasible or not. It took me a long time to work out the pre-post eq/clipping 4PDT for my Cirrus, eventually I caught a mistake I'd made in logic/flow — and now I think it's good to go.

What's great about this 9-pin is the commons have both closed and open modes.

Hmm...

 

[Robert]

A switching jack wouldn't even be necessary.

If nothing is connected to the CTRL pad then the module behaves like a standard relay bypass module. (No latching/momentary function, but otherwise standard operation)

Of course you'd need two jacks in each pedal (or some other means of daisy chaining them together).

Tough choice, then:

1/4" jacks for easy of using regular patch cables (but at the risk of connecting audio to the CTRL)
1/8" jacks for easy distinguishing which is audio/which is CTRL signal (but at the risk of not having a spare 1/8" cable when one goes down in the middle of a gig).
