    #42 PE, about 7,800-8,000 turns for stock neck. I usually wind them to about 8,500, sometimes more.
    The early 70's J bass pickups are pretty weak sounding.

      Hi Jim:
      That is a fine looking 73 Jazz.
      I redid a few in the 74 range, and they were all warped and mangled.
      I like to keep the neck pickups wound on the lower side.
      7500 ohms or less, in the 8500 turns range.
      I show this screen shot in the ball park.

        Thanks Stratz. The specs I can find for the early 70's seem to be running in the 6.6kΩ - 6.8kΩ on the necks, but apparently the current Fender reissue version is ~ 8.3kΩ. The client will have to decide where he wants it to land.

        Thanks again.
        Take Care,

          Thanks Terry. Yes, from the pictures the guitar tech sent me, the physical pickup looks very "clean". I did check the coil estimator, but am never sure about the wire size listed for particular pickup, so I thought I'd ask the question. It will be interesting to see which way the client wants to go re: output range. When I looked at the SD FAQ, it had the old at 9,000 turns and the new versions at 8,000 turns. Your 8,500 looks pretty safe.

          Thanks again Terry.
          Take Care,

            I agree on the wire size.
            PE can be all over the place on ohms per foot, and wire size.
            The 74s I rewound were dipped in some dark looking varnish.
            They were all corroded and broke where they touched the magnets.
            A set is RWRP, and I can't remember for sure without looking at my shop notes which is which.
            I went back without the varnish, and wax potted them.

              What ohms/1000ft. are you using in that calc Terry? I'm having difficulty replicating the results with the online version of the coil estimator.

                  Thanks Terry, I figured it must have been something along those lines.

                    All done. Put 8,000 on it. Came out at 6.93kΩ. The bridge was at 7.12kΩ according to the customer. Looking forward to the customers feedback.

                      I rewound a '63 neck a couple of years ago and went with 7500 turns, about 6.3k. I had intended to put more on it but was curious what the lower winds would sound like. Of course the owner loved it just the way it was and wouldn't let me add another 1500 turns so we'll never know. Basically I don't think it much matters what you do -the customer is either predisposed to like it or not. Maybe it was those '63 alnicos that gave it the glorious tone? More than likely it was that the pickup had been dead from before the fellow had bought the bass so he'd never heard it and anything was going to be a big improvement.

                        I bet 7500 sounds good, and I bet the 8000 sounded good also.
                        I like neck pickups on the underwound side.
                        I usually underwind on the neck, and slightly overwind on the bridge.
                        However on my own stuff, I tend to route bigger holes, and install soapbar side winders, Multi-Coils, or Humbuckers.
                        That's a topic for another thread!

                          Rewinding all three pickups from an old Silvertone which is in mint shape .
                          Customer wants more output as all 3 of these are only about 3.5k



                          3.5k probably 4600 turns
                          Black wire =finish wound Clockwise
                          Red wire =start
                          Green= grounded to plate
                          40-50 tpl
                          seems 40 one way & 50 when traverse goes the other way .
                          with fairly tight tension as these soft bobbins have quite the flare going on
                          wire .0031" could be heavy 42 gauge or 41 but bobbins are not full
                          & are not potted

                            Great info Copper! Very cool pickups, and pictures.
                            Could you give out the bobbin core measurements, so I can put them in the data base?

                                That is a nice setup.
                                If you get time, a picture of the bottom of the pickguard would be great, and it would show how it all ties together.
                                Here's the layout I came up with, you can tell us if it got close?
