Hi all. Dumb question likely. I'm kind of a noob at this and am planning on building a relatively simple tube overdrive. I'm not using a pcb and I'm just researching some different wiring diagrams and such. Every generic foot switch wiring instruction i find seems to involve a pcb. My question is: If you have no PCB, then where do the wires that would normally route from switch to the in/out on the pcb go to?
