How Can I Measure a Pickup in Detail?

    I have a Fluke 87 iii that serves well for measuring DC resistance and (milli)voltage, but I also need to measure the inductance and resonant peak of a pickup. I assume that I will need additional tools to accomplish this, but would be happy if my existing DMM can pull this off.

    Any thoughts?

    Also, is there anything else I should measure in order to help quantify a pickup's tone?

    Thanks.

    The point is that a pickup is not an inductor thus inductance varies with frequency.
    I guess measuring It at 1kHz is representative enought.

    Here's my guide http://guitarnuts2.proboards.com/thread/7723/measuring-electrical-properties-guitar-pickups

    Im not familiar with the Fluke 87, but it would need to allow inductance testing at 100Hz, give or take, and simulate a series RLC circuit. Meters like the DE-5000 can do it and are fairly cheap.

    If you know the inductance you can determine the peak freq to a close by making some safe assumptions about the capacitance. If you name the type of pickup, I can probably tell you what sort of capacitance to expect from it. Since the guitar cable supplies most of the capacitance, its not necessary to be to super accurate.

    Thanks for the responses, guys.

    And I can tell that Antigua Tele has put a little thought into this. :D That's what I was looking for.

    As for pickup type, I have several PAF-ish humbuckers that I like in various six string guitars (different manufacturers, different magnets, etc., but all PAF-ish). I am trying to get a ballpark idea of what I like about these so I can find a similar 7 string pickup for my 7 string guitar. unfortunately, most 7 string pickups are overwound, have ceramic magnets, etc., plus they will have a wider bobbin, so it's a bit of a challenge.

    Consider getting the hottest 7 string pickup you can find, then wire it in parallel. If it has a ceramic magnet, just lower the pickup a little to approximate a pickup with a weaker magnet.

    That's an idea I hadn't thought of, so I'll definitely keep that in mind.

    I also traded a couple of stock Ibanez 7 string pickups for a set of set of Dimarzio PAF 7 pickups (which have ceramic magnets for some reason), so I'll check those out, too. If I can't get them to work, I may try swapping magnets around to see how that changes things up.
