    OK, I've got a stacked pickup - I like the full on tone as a "boost" position, but it doesn't play well with the neck - and doesn't allow a twangy bridge pickup tone.
    It does these things well when split.

    I'm probably just being blind, but how would one wire a 4 switch to give.

    Neck
    Neck+Bridge(one coil)
    Bridge (one coil)
    Bridge (Both coils series)


    First 3 positions I can work out - almost regular tele wiring. but the forth position is eluding me.

    put a push/pull on the pickup to go from bucket to single coil or from series humbucking to parallel humbucking.
    The leads from the switch go to the 4-way.

    I guess If I do it with a push/pull I could do it with a regular old 3 way - I don't want neck/bridge series in any combination anyway.

    .

    The above suggestion is in addition to the 4-way you need a toggle or a push/pull to do what you want.

    Four way will get you series/neck/parallel/bridge between the pickups then if you want the bridge to be either single coil or humbucking you use a toggle or push/pull.

    You might bend a 5-way super-switch to your exact switching order, but they get pretty complicated to set up.

    I'd suggest a 3-way on/on/on toggle switch to change the bridge on its own from parallel/single/series and then the 4-way to do series/neck/parallel/bridge operations between the two pickups.

    Or you use a 5-way switch to run all three coils like a Strat and you have a concentric tone/blender pot to go from SSS to HSH.

    Of course, the easiest is a 3-way Tele switch with a push/pull to split the humbucker.

    The switch
    I searched the web and can t find a schematic for a 4 way .. Is it 2 pole 4 position w NO shorting of adjacent positions? If so you can do your switching...
    The 2 poles are +A and +B.
    4 Neck.....+A hot from Neck
    3 Neck and 1 coil of Bridge....+A Neck hot, +B Bridge coil junction
    3 Bridge one coil...+B Bridge coil junction
    4 Bridge... +A Bridge hot

    It depends how the Stack is wired you may have to reverse the wiring if the bottom coil is grounded.

    You've more or less described what I drew in the post above you.

    Sure enough. Problem solved. Bridge South would be the top coil.

    I like more versatility than that when I have 4 wires on a pickup ..or two....and a four way switch. ommv.

    And of course north and south could be swapped in the diagram, if desired.

    For a full size HB, I usually try to split the outside coil, to get the most separation.

    FWIW it's also thinner/brighter - assuming it's in the bridge position and the outer coil is closest to the bridge. If it's in the neck position the game changes....

    Ah, wording... when I said "outside" coil, I meant the coil closest to the bridge, in the case of a bridge pickup. Or the one closest to the headstock in the case of a neck pickup. I try to avoid getting that positional wording conflated with north/south, start/finish terminology.

    So, yeah, I figure if you want to split the bridge, you want that bright sound. Why do you say the game changes with neck? Because one might wish for the bridge-most (aka inside) coil, to achieve a more balanced, less muddy sound? If so, I could get on with that. I figure at that point it's personal taste.

    I have no dog in the fight, I just make wiring diagrams for people who want them. I used to wire my guitars all manner of ways, but since I never used any of it, I no longer bother.

    The "outside" coil is the "screw coil" and is normally closest to the bridge - on the bridge pickup.

    Because the neck "screw coil" is normally closest to the neck (yeah, I know that sounds weirdly redundant - but some might no know) and will be "less bright" than the slug coil.

    Perfect, just what I needed, sometimes I get dumb moments where I'm outsmarted by switch logic.

    That's my point. We're talking about the same thing.

    Oh, I know the feeling.

    After staring at Fender switches for so long, I have a healthy respect for the efficient, clever design. I've never seen these exact switches (3, 4, 5 way) anywhere else, I wonder if Leo had a hand in inventing it?
