    Hi all,

    Does anyone have a diagram for wiring two a 2 Humbucker
    guitar as follows

    (At the moment
    With the switch in the centre position

    Reducing the bridge vol control to zero
    has the affect of reducing the total guitar output to zero)
    ----------------
    I would prefer that reducing the bridge vol to zero
    only reduces the bridge PUs output to zero
    (leaving the neck PUs output as is)
    ----------------
    I hope that I have explained the issue clearly .... !

    I know it is possible to achieve what I want because
    I have another guitar (an Ibanez AF120) that already works in that way


    Many thanks

    Not sure if this will help, but here's a wiring diagram for the '95/'96 AF120.

    Can anyone tell me how their 2 PU Gibson behaves

    with respect to .

    with switch in the middle position
    Bridge volume control at zero

    Do you still get output from the neck pickup ? or not ?

    My Gibson 175 with 2 humbuckers is wired that way. When in the center the bridge volume control will kill all output.

    My Gibson's also have no output if one of the pickups are turned down all the way in middle position.

    There are two ways of mixing two pickups that leave the pickups connected directly to the output when the volume is up full

    Go down to the Alternate volume control wiring

    OMG yesss !
    Yes that now all makes perfect sense ....

    Thank you so much , I couldn't get my head round it
    (It's quite simple when you know how)

    It's not a biggie so won't be doing the change soon ,
    But when I've next got to get the guitar on the bench
    I think I will change it to the 'alternate vol control wiring'

    big thanks again

    My Epi ES175 is wired that way. It can be disconcerting until you figure out the cause of the silence. But it can be a handy way to kill silence the guitar temporarily, for whatever reason. I've just been too lazy to change it, since it's easy to just turn up the bridge volume a little. Doesn't take much.

    By the way , in case anyone's still interested

    The Ibanez July 96 AF120 wiring diagram kindly posted below
    by ...... Jazzshrink
    Is not correct for my AF120
    (There were a few different factories making Ibanez guitars ....)

    I'd be interested to know if you've got a 2 PU Ibanez jazz box

    How it behaves in the middle position ?

    This doesn't directly address your question, but guitars can come out of the factory wired incorrectly. I had an Eastman, and I didn't like the sound of the pickup at all. I replaced it with a few others, and it sounded okay, but I decided to sell it. I stared to reinstall the original pickup, and looked at the Armstrong website for the wiring diagram. I found that the wrong wires were connected together, and to the volume pot. After I rewired it to the Armstrong diagram, it sounded so good that I decided not to sell it. The factory had just wired it wrong. All sorts of things can happen in a factory.

    So I just did the mod above ....
    In fact I only did the mod on the Bridge Vol pot

    It worked great !

    Ie
    In the middle position
    Reducing the Bridge Vol pot to zero doesn't kill the output

    (incidentally , reducing the neck vol pot to zero does kill the output
    but that's good for my needs)and

    Very happy
    Thanks all

    One general word of caution when dealing with 4 wire guitar circuitry: When it comes to 4 conductor wiring, wiring is not standardized. The colour coding in a Duncan is the same as a Gibson but different from DiMarzio, for instance. You can't rewire a pickup replacement wire to wire if you're following colour coding, not until you look up that pickup manufacturor's wiring colours.

    Just to keep in mind when you're using a diagram that specifies colour connections.

    Glad you like it. I wire all my 2V guitars that way and can't see any reason not to.
