I just bought a small synth for my pedal board (Modal Skulpt) and my goal is to have it on my board and be able to play it into my looper, and then play my guitar once I’ve got a loop set with the synth. Basically, a mixer with multiple inputs and a master out to the amp in theory (I’d like something more minimal thanking a honking mixer on my board). I want to be able to run the synth through pedals and be able to switch back and forth between synth and guitar without having to mess with pulling cables out of inputs. Is this making any sense? Almost like a reverse A/B box after the guitar and synth, then feeding into pedals. Is that a thing? Help appreciated!
