    Info On This Vox Pickup

    This is out of a Vox Voilin bass. I've never seen one or worked on one.

    Any idea what it is or what sort of wire was used? The coil is taped and I've yet to tamper with it.

    The other pickup measures 9.7k.

    EDIT: This is a Hofner pickup.

    Well nevermind. It's a Hofner 512b from the late 60's and wound with 50mm wire.

    wound with 50mm wire
    50mm is about 2 inches
    maybe you mean 0.005mm wire (5 thousandths of a mm) which amounts to some AWG 44 .

    There's quite a bit of info/inside views of Hofner pickups here - Hofner Guitar Pickups
    Their designs are interesting to study...You can tell they tried to make the most out of each magnet with all sorts of metallic gizmos, and some of those pickups sound really nice!

    Hmm... 44AWG is .002" or .051mm -no?

    Yup. Those pesky decimal places...

    Probably.
    Fact is AWG scale is not linear so some equivalences are either not exact or need a long string of decimals ... which is irrelevant because there´s quite a tolerance spread on very thin drawn wire, specially if copper.
    Just check Elektrisola (or any other) wire tables, tolerance can easily be 5 to 10%

    As in:
    Gauge: 42 AWG & 43 AWG, 44 AWG
    Weight: 1.0 Pound Each
    Length: 42 AWG - 51,313 Feet (approx.) • 43 AWG - 66,092 Feet (approx.) • 44 AWG - 79,798 Feet (approx.)
    Diameter: 42 AWG - 0.0026"-0.0028" • 43 AWG - 0.0023"-0.0025" • 44 AWG - 0.0020"-0.0022"
    Insulation: Solderable Polyurethane
    Build: Min-Nom
    NEMA Description: MW-79-C
    Temperature Rating: 155°C (311°F)
    Color: 42 AWG - Natural • 43 AWG - Natural • 44 AWG - Red
    Reel Size: 2.5"x3" Spool
    Manufacturer: Elektrisola

    Juan, we're not talking about tolerance out to a long string of decimals. We're talking about order of magnitude.
    You told jrdamien "50 mm is about 2 inches"- which is correct.
    You went on to say "maybe you mean 0.005mm wire (5 thousandths of a mm) which amounts to some AWG 44"- which is incorrect.
    AWG 44 is approximately 0.05mm (5 hundreths of a mm). So your "correction" was off by a factor of 10.

    If I had better language & social skills, I would have said this more clearly & succinctly, and in a playfully teasing manner.

    EDIT
    How's this? "Hey Juan, is it true you worked on the Hubble telescope?" Nah, too snarky.

    0.002 inches ~= 0.050 millimeters = 0.005 centimeters

    You're right, I didn't read the attachment.
    So we agree: 44AWG = .0020"-.0022" = .051-.056 mm (to 2 significant decimal places).

    Right again- I saw it wiggle too.

    Think you are making a big point out of a very small one.

    And yes, I typed one extra zero, so sue me, the main point was that pickup wire was NOT 50 mm, a FOUR orders of magnitude error now that you insist on that , anything else comes in its wake.
    I even got close with the AWG value, which I included just as a courtesy to you Imperial heathens

    Oh well, no good deed goes unpunished, just ask some moderator to remove all of my posts in this thread, which I should have left unmolested.

    Of course. That's what we do.

    It's not that. It's that you wrote out "5 thousandths of a mm", then when David corrected you, due to a coffee deficiency or similar malady, you misinterpreted what he said and went off on a tangent about manufacturing tolerances.

    Yes, I'm still chuckling about that. Two inch thick pickup wire, tee hee hee.

    Lucky guess.

    No way. This is going on the wall of shame.

    So you're all saying *don't use 2 inch diameter wire?

    Well it's too late now!
