On my pedalboard, there are just 3 pedals that I have not built: a tuner, a POG2 and a Palmer Triline.
I'd like to try and build something similar to the Palmer Triline, but I really don't know where to start: it's an ABY pedal with a switch for A, a switch for B and a switch for Y. I assume the switching is operated with use of relays, but can figure out how to do the logic... would it need some kind of microchip controller?
