Seymour Duncan JB humbuckers are such a classic pickup, loud and aggressive with no shortage of high end attack. This particular one has had a hard life and finally gave up so it arrived at my workshop for repair. It’s not the first Duncan JB Re-Wind if had to do but this time I’ve taken some pics.
This one had stopped working altogether. With the tape off the hook up wires are exposed and it’s possible to identify which coil has the problem. It’s usually just one coil.
It turned out to be the coil with the screws in this case.
The coil with the lugs in fine and showing 8.42KOhms and from that I can figure out what size wire they used and calculate the number of turns needed to re-wind the duff coil.
Pretty routine stuff this Duncan JB Re-Wind but always nice to have a look inside a classic pickup. https://mrglynspickups.com/
Pickup re-winds are a big part of what I do.
In the early days back in the 1990’s I re-wound a lot of pickups. It was an invaluable introduction into the inner workings of electric guitar pickups.
Back then there were a lot of 60’s and 70’s quality pickups around to practice on, they weren’t as valuable or sought after as they are now. Because of that I got to see how pickups were put together in the old days, the construction, the potting material…
There wasn’t much information available so experimentation was the only way to learn. I made so many bad pickups back then but made a note of every single one, how I’d wound it and what the result was. By using that method I got closer and closer to what I wanted. I also made a note of all the re-winds I did and the original spec if I could get it. I’m still writing in that note book to this day and it’s becoming a fantastic reference tool when I receive an unusual pickup repair from a customer.
I still really enjoy re-winding pickups, I think I have a strong instinct to fix things. I would much rather repair a faulty old pickup than sell a customer a new one. Sometimes, of course, the customer wants a different sound that the old pickup can’t give them and a new pickup is the way to go.
Please feel free to contact me about any faulty pickup by email (firstname.lastname@example.org) or by phone (021 912 678).
