/diy/ - Do It Yourself

Hey there anon!
I understand that 3PDTs can be expensive sometimes, have you checked out taydaelectronics.com? I buy my 3PDTs from there, they usually run for around 3-5USD apiece. But if that's still not an option, I would say that's perfectly possible, mechanical relays are suited for that, they will work just fine. I've seen that design used before:

A popular DIY effect pedal builder Randofo uses a push SPST to drive a DPDT relay to control the effect/bypass switch in his circuit.
Unfortunately he provides no explanation as how to wire the relay, so I guess that's less helpful than it sounds. Sorry mate.
As for your criteria, I would say relays for switches are efficient in space, tolerable in price, and reliable in quality. I wouldn't worry about a relay's lifespan when used to toggle a stompswitch.

I know that transistors are also viable in some desgins, but I'm not experienced in using transistors for effect switching, but I do know that the RAT uses a DPDT for LED indication and bypass switching.

Good luck anon!
