Help requested: Why does the middle position suffer from a volume drop?

    .. and what could I do about it.

    This Fender Jaguar, a workhorse in a Grunge Band, has undergone a bridge pickup swap. Originally it was equipped with two P90s (neck: 7.8K and bridge 8.25K). It's owner let me put in a Dimarzio Super Distortion DP209BK (13.2K) to enhance ...distortion. I set it up to be just a tad louder than the neck pickup. Both pickups sound fantastic on their own and they complement each other. But if I switch to the middle position there's an annoying drop of volume. I don't think the pickups are out of phase - it certainly doesn't sound oop.

    What went wrong? Any ideas for a cure?

    Are you sure they're not out of phase?

    If they're out of phase there is a drop in bass in the middle position.

    Out of phase... I cannot see any other simple explanation (for exotic one there is still open quest )o_O

    OK I was just checking again. There is a very little loss of bass but it's far from sounding thin-ish. Nevertheless I'm going to swap the phase of one of those pickups at the selector switch.

    I hear a volume drop on any guitar when two pickups are combined in parallel, though some more extreme than others.
    Maybe here it's more pronounced due to the pickups being so different?
    Unless it is indeed just a phase issue.

    Anytime two pickups are combined in parallel you will have phase cancellations at some frequencies. Depending on your amp settings, you may notice it a lot.

    Well, no, if they are out of phase even the bridge pickup alone will have more bass than middle position, but I'm not sure you know how to reverse the phase.

    Hey radiocaster you were completely right!!
    It was out of phase and in addition I had to repair the selector switch which had already been dodgy and finally went kaputt. That's what kept me so long from answering.

    Thanks to you all!! Problem solved!!!

    You have phase cancellations on the harmonics, not on the fundamentals... As the larger part of the string energy is in the fundamental you cannot have a proper "volume drop". If we are talking about "presence" and cut out thought the mix, that's another story

    Oh, definitely.

    This has been my experience forever, but I never "noticed" it as a "defect." Granted, mine were never ridiculous drops, but they're certainly noticeable.

    Which is why God invented 4-way switching to include wiring in series.

    When I play a strat, the in-between positions are not as loud.
