    You schematic shows no coil split, and the humbucker is wired in parallel. Add a push pull pot to the volume control for the coil split (wired in series) , and a 250k no-load tone pot.

    Actually, I think that schematic is correct. The "other" side of the switch (that is not switching between pickups) is grounding the humbuckers series coil connection when in the second position effectively eliminating the first coil.

    Look at the hb wires. The coils are parallel.

    In terms of Seymour's color code the coils are wired in series - standard humbucking. The black auxiliary ground wire off the switch will then nullify one coil when in the 'in between', at least that appears to be the intention.

    The frequency imbalances have now been mitigated to a satisfactory level.

    Installed a 500K no-load tone pot - that and swapping to the shorter screw-coil hex screws and lowering the pickup brought the HF up where it balances much better. It isn't perfect, but no guitar ever is. Sounds great in all positions now although the humbucker's mids still are quite prominent as compared to the same pickup in the other two guitars, but I can live with it.

    The above diagram indeed splits to the slug coil in position 4, which also puts the split slug coil in parallel with the middle humbucker. I don't need or want the bridge to split by itself.

    There are a ton of players out there that wouldn't complain if their guitar was more mid heavy in the lead pickup Use it for what it is and does. Enjoy.
