I am trying to build different pedal designs and would like to add a simple Dry/wet knob on my photo board.
Would anyone have something in mind, a direction to point me at? Maybe a dual pot configuration?
I would imagine a single (linear taper?) pot should do just fine - dry and effect to the two ends, and output from the wiper. Although you'll probably want to add some buffers both before and after the pot, to remove the chances for weird interactions.
