I recently assembled my dream partscaster. It has two Duncan humbuckers, both 4 conductor. I set it up with a 3 way blade switch, a master tone, a master volume, and a 2 way toggle for cool splitting the pickups (one position for full buckers, one position for split singles). I am a caveman, so I brought it to my local tech for wiring. He told me that it's not possible to split both pickups with one 2 way toggle, and that it will need a 3 way toggle or a second 2 way toggle. I've had several guitars that are dual humbuckers split by one push/pull tone knob, so it seems one toggle switch should be able to split both humbuckers, right? Am I on the wrong path? Again, I admittedly know nothing about wiring/electronics.
