That'd be a little too opaque to me; I'll probably go with a series-single-parallel switch for the two rear pickups, so that I retain my "middle only" option, then the blend to determine how that composite signal combines with the neck P-Tone.Could always go nuts and get an 11 position rotary switch...
So the bass will have 4 knobs and 3 switches, but it'll make sense to me, and give me rapid access to my preferred tones.
