    Default Impossible to Coil-Split a HH With 2V & 2T?

    I've been told one can't do this and have all the volume & tone pots functioning. Haven't given it much thought, but decided to run it by the gurus here.

    Not true. The circuit to split is independent of the tone controls.

    Heré´s the wiring diagram for that setup in a Les paul with independent coil splits.

    In the diagrams, push-pull pots are used. But you can use miniswitches instead with zero issues

    Ah, OK, cool -- but I'd really like to do this with a rotary switch in the current 3-way switch hole.

    We need more info. Will you still be using the same 3-way? What do you want those 3 positions to do? What kind of guitar?

    It's a Fender with OEM:
    1 Seymour Duncan® SH-1N RP ‘59 Reverse Polarity Humbucking Pickup (Neck),
    1 Seymour Duncan® SHPGP-1B Pearly Gates Plus Humbucking Pickup (Bridge)
    ...with the full factory leads for coil-splitting.

    Stock wiring is just the usual HH/3-Way/2V/2T setup.

    I was thinking about replacing the 3-position neck-both-bridge toggle switch selector with a rotary switch of some configuration to do something interesting -- dunno what, exactly...it just seems a waste not to take advantage of those split-coil leads somehow.

    I'm a former professional P2P audio assembler, so I'm not averse to some tricky wiring and precision soldering if I have a clear wiring diagram or schematic from which to work.

    I'm open to any suggestions, including leaving it stock. Thanks for any help!

    I'll have to think on this a bit. The problem is, the 2vol/2tone situation. That actually makes it harder to come up with something, other than the standard splitting of the 'buckers. (Which isn't bad.)

    I'm just putting the final touches on my favorite dual-humbucker wiring, but it only works with a 1vol/1tone layout. Its what I call my "virtual 3rd humbucker" configuration. (I believe its what PRS does with their rotary switch.) It just takes the middle position of an ordinary Fender 3-way and creates a virtual 3rd humbucker, by using the screw coil of the neck in series with the stud coil of the bridge. I have one of my Tele's wired this way, and will soon be converting another.

    Its my favorite dual-humbucker tone. Here's a link if you want to see the basic layout. If you do wiring, you shouldn't need any explanation of this diagram. Just note that the pups aren't shown in their physical orientation, but their electrical configuration to make the drawing "neat".

    Virtual 3rd Humbucker

    The diagram shows three views of the same thing. The last group shows the three switch positions. (Electrical path shown in green.)

    Hope this makes sense.

    hey artie; will your virtual 3rd humbucker work on this style of switch?

    Unfortunately, no. You need a 3TDP minimum. This switch will work also, because each "half" can be configured for 3TDP operation. I just don't like it because of the short handle. (And the cost.)

    Wait, so are you saying that "standard splitting" isn't hard with an HH w/2V2T?

    I'm slightly confused here.

    Standard splitting (each pickup individually and when desired) is the diagram posted above, and it´s much easier than automatic splitting where you first have to think about which coil and when... I think that´s what Dr. Too means

    Exactly. Standard splitting is simple with anything. It just depends on what switches and configuration you want. There are limits, but it isn't difficult.

    If you get the time, peruse the Duncan schematics. Lots of good info and ideas there.

    Well, the guitar arrived today and the whole question is moot, as the info from Fender is wrong: Only the bridge pickup is wired for splitting.

    Sorry to waste time here, but blame FMIC.
