Also all the examples that I have seen (3 of them) had fewer turns on the "Staple" side. Here's one example where I had to rewind both bobbins.

    Hope this helps
    Thanks Sonny. The info and data are very much appreciated. Yes, it's a '65 Beatle Bass. I had one in a couple years back for a rewind on the staple side (I used 44 SPN). The screw side on that one was still good and ~4.83kΩ. I wound the staple side a little hotter, but based on your notes, I'll definitely go the other direction on this set based on your notes.

    A DiMarzio Chopper T Tele bridge pickup came into the shop yesterday. I have never dealt with one of these before. My question, is the Chopper T epoxy potted (or any such potting that is other than wax). It was in for excess micorphonics, but it looks and feels like it is not coming apart without a hammer. If it's epoxy, I can't see wax potting is going to get in there.

    More questions later on an Ernie Ball Stingray 4 Music Man bass pickup that came in with the Chopper T.


    ...........................................

    followup. . . wax potted per Dimarzio tech support.

    Yeah, I've figured that much.

    Unfortunately, IME, Metalheads are impervious to tone. Or at least what *I* consider tone is, that is...

    Man, do I sound like a triggered grandpa! Kids, get off my lawn!

    I'm oooooooooold...!

    I can't believe somebody actually wanted to rewind a Dirty Fingers.

    Man, what a tone-less p'up. The quintaessence of a one-trick pony. In my case, I couldn't even find the pony, but a stubborn donkey.







    I still have it, it's a 1978 one, wound on Schaller bobbins, taken out of a Koa Gibson Explorer. I might one day rewind it with PAF specs.

    Here's a copy of John_H post on the main forum.
    Maybe he won't mind me borrowing his post!
    Goes good with all the bizarre pickups that get rewound!
    Great Pictures.

    The bizarre guitar pickup encyclopedia. It's too bad there isn't more info, but the high res pictures are good.

    I made adjustments to my SD Seymourized SM3-N, and SM3-B, data to reflect actual bobbin measurements.
    4400 turns of 42spn, and 5500 turns of 44spn, will get you close for the SM3-N, and SM3-B pickups.
    Here's the updated data.

    Was cold in my shop today, but I worked on the Mini-buckers a little while.
    I thought a SM3-B Mini bucker that measures near 12k, was probably wound with 43spn.
    After micing the wire, I descovered that it is wound with 44spn, instead.
    I ended up putting 5500 turns of 44spn on each bobbin which gives it the same bobbin fullness, and DCR of a SM3-B, just less that 12k.
    I will modify and post my data, later, to reflect the 44spn, instead of 43spn.
    I have both pickups ready to assemble, and pot tomorrow.
    The neck pickup was still good, so not rewinding it, just replacing the cover.
    It measures about 6.3k, I presume the SM3-N is wound with 42spn?

    I wound and potted the Dirty Fingers, and there were no surprises.
    The pickup with 2-44awg, 6500 turn bobbins, wound up around 14.8k, which is what I was shooting for.
    It's not unusual for me to break or screw up 44 awg wire, when I wind bobbins by hand with 44, until I get used to it.
    No problems today, and they both wound without a hitch.
    I'll work on the mini-buckers tomorrow!

    I'm fixing to rewind the Dirty fingers, and I stripped and prepped the bobbins.
    This pickup will be used by a metal player in the neck position.
    The owner player, wants to keep the pickup wound with 44SPN, but a little less winds than the bridge.
    The bridge uses 7100 turns per bobbin to make it around a 16+k pickup.
    I plan on winding this neck to 15k or less, with 44SPN, using 6500 turns.
    Your rewind comments are welcome!

    I have some pickups to repair and rewind.
    Another dirty fingers.
    Two SD SM-3B, 3N mini pickups.
    One needs repaired, and going to replace the Cover with Stewmac plain type Firebird covers, on both mini's.
    I will keep a record of the process.
    Here are before pictures.
    Probably be Monday before I tear into them.
