2 Effects on box. 2 Foot switches to toggle between either or bypass

hey, welcome back, i guess...

fun read, this thread! i really like that you found a way that works, but now im curious for a way to do this without digital controller. id use boss style Jfet switching to not use expensive relays.

cheers

What a fantastic idea!
So, you mean just replacing the relay shield with JFET switches?
The Arduino just outputs to each relay to engage or disengage which ever signal chain.

We developed a circuit without micro controller at the german musikding.de forum a few years ago:

Attenzione! The schematic doesn`t show the final circuit - read posts 30-40. The veroboard layout is correct.
