Pickup Rewinds

[big_teee]

I had a request for info on a Duncan JB.
I don't have the tpl, but here is data for a starting place.

When I get back from (retired person) vacation, I have an early 60's 8 string Fender 400 (jazzmaster style) steel guitar pickup to rewind. This is a new one for me. The customer has the original but wants a replacement he purchased and found way too hot for his liking rewound to get to the tonal characteristics of an original. Most I can find so far is the manual as well as a webpage from pedal-steel-guitar indicating the early 60's versions where wound to ~ 10.12K. Does anyone have any resources or info they would be willing to share on this vintage pickup?

Not sure about 500/501 unless that is the guitar model (beatle bass). All the staple type Hofner bass pickups that I have rewound were Model 511B. Those ranged from 7.95 to 8.34 K ohms and all were wound with #43 SPN wire. I rewind them by measuring and precisely weighing the wire so I can calculate the original DCR and number of turns. 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.

'65 Hofner bass 500/501 pickups (staple style). . . ~ 8.75kΩ - 9.25kΩ with 44AWG?

Thanks in advance for any input.

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.

I rewound those for a metal player. He loves them!

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...!

Depends on the music you play.

All back together and back to the Post Office.
Was a fun project.
Dirty Fingers Neck, 14.8k, 6500 turns 44SPN
Seymour Duncan SM3-B, 12k, 5500 turns 44SPN
Seymour Duncan SM3-N, 6.4k, turns unknown, wire most likely 42SPN

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.

Anyone have any rewind data, and or pictures they want to post and share of your rewinds?

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.

[big_teee]

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?

[big_teee]

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!
