I'm planning out a project in my head and wanted to bounce an idea off of you guys. The pickups I'm looking to get will either be Nordstrand Dual Coils or Delano SBCs. I'm open to suggestions of course, but these were my initial options that came to my head. The design will be in a four knob configuration. This will be entirely passive. I would like the ability to swap between series and passive wiring as well as change each pickup (separately) to single coil mode. My first thoughts are the traditional VVT, but that only utilizes 3 of the open 4 places. Also, I don't really like this configuration at all as I lose the ability to do volume swells cleanly. So what I was thinking was a Master Volume, then two individual pickup volumes, and a master tone. The master tone knob will be push pull to change between series and parallel. Each pickup volume will be push pull to change either pickup into single coil mode. This would allow me to have every ability I'm looking to accomplish while utilizing all current knob openings with no switches. How feasible is this?
