I am considering modifying the typical passive 3-knob setup Vol(neck) / Vol(bridge) /Tone and curious to know if anyone has already done this:
Neck Volume knob becomes master, Tone knob unchanged
2nd (bridge) Volume knob modded to 4-position rotary detent knob: neck pickup 100% (and bridge pup off) , both pickups 100% parallel , both pickups 100% serial , bridge pickup 100% (and neck pup off).
I believe this would also be humcancelling in all 4 positions. So the completed mod would retain the 3 knobs and unchanged look, but the knobs would be Volume, Rotary Pup Selector, and Tone.
I never blend pickups, only use either full-on neck or bridge depending on the sound i'm after, and i've also found that serial connection adds a wonderful fullness to the entire frequency range that is missing from the stock passive sound (at least to my ears).
