    And so today I was taking out my Gibson ES-345 Stereo Guitar outta storage to clean her up and do some maintenance on her. Well I decided to take a reading of the Humbuckers that are in her. The Neck measures out at 8.66 and the Bridge measures out at 9.27. That can't be right HuH ? She's a 1966 according to the serial number which is 368967. She has unopened Patent Number Humbuckers (Gold Plated). Are the readings possible ? Or am I hooking up my ohm meter incorrectly ? Thanks for any comments or assistance to the aforementioned query.

    Those readings are possible, especially if you are hooking up your meter to the guitar's output jack and not the unsoldered pickup leads, directly.

    Another possibility is that the pickups are warm at the time of measurement, if you are metering them directly.

    Another plausible possibility is your pots are not zeroing out on 10. Very common on old pots.

    I don't think those numbers are hard to believe, but they should be tested while unsoldered (which I wouldn't wager is worth the trouble). The parallel resistance actually decreased the measured DC resistance by some amount, because it gives the current an another path of travel other than the pickup itself. The actual DC resistance can be calculated by accounting for the 500k pot, but you also have to know the precise resistance of the pot, which probably isn't a perfect 500k, or just assume it's 500k (assuming that's what they're spec'd at) and that would get you closer than an output jack reading alone.

    Agree with the others, not 'out of spec' at all. If the pups were unsoldered the reading would be even higher by about.20

    How does it sound?

    Then those readings are affected by the Varitone circuit. Pat#s clock at 7.5K on average.

    Don't sweat it. DC Readings have absolutely nothing to do with tone.

    HTH,

    Pat number decals and nylon saddles. Mmmmmm, that's a nice combo!
