    Gibson pickup malfunction

    Hi everyone! I have a '78 LP Custom. It has its original pickups, but for some reason the bridge pup sounds thin and measures 1.1 kohms (the neck pup is perfect, 7.44 kohms). The pots have changed about a year ago, but the pickup functioned the same before that. Don"t know if it's a problem or not, but the measured impedance grows, and doubles while turning down the volume pot (same for both). Is something wrong with the wiring or the pickup needs a rewound?

    Both neck and bridge PUs should have about the same DCR (around 7.5k). To make sure it's not the wiring, disconnect the hot lead of the bridge PU from its volume pot and measure it on its own. If it still measures low it has a winding short and needs to be rewound.

    Thanks a lot! Double checked it and yes, sadly the problem is in the pickup.

    I was also hoping for a picture of the pickup and the old guitar. (topside)
    Unsolder, one side of the pickup from the guitar, read on ohms, to get an accurate reading.

    If after you're done repairing the pickup, and the guitar is noisier than you want?
    Replace the shielded cable, with a piece with no breaks from jack to 3 way switch.
    2 more from switch to pots. It really does make a difference, and I have done it many times.
