Cool idea. Myself, I don't do well with foot operated stuff, but it's a cool idea.Something I've never seen done but might be interesting for the minimalist out there - no volume or tone pots, just a pan pot or mix slider on the bass. Then plug into a volume pedal on the pedal board to adjust overall volume. For the pedal board fans it might be a neat option. Certainly would give a different look to the bird with no knobs and instead a slider.
You could always have two sliders... volume and pan.
