I had a 1975 Wide Range’ humbucker in for a rewind the other day and took the chance to take some pictures. I thought I’d explain why these are different from ‘normal’ humbuckers and show you what its innards look like.
The main difference is with the magnets. A tradition ‘Gibson ‘ style humbucker has a single bar magnet underneath the coils with the pole pieces ‘conducting’ this magnetic flux up through the coils towards the strings.
The Wide Range is much more similar to a Fender pickup (like a Strat) with the poles being individual magnets, 12 of them. This produces a more trebly, percussive, clearer tone than a traditional humbucker. To offset this high end Wide Ranges have overwound coils. The more wire you put on a coil the more bass you get so Wide Ranges are wound to around 10.6KOhms where as a traditional humbucker is closer to 8KOhms. This adds bass and balances out the tone from the magnets giving a balanced, full, clear tone. To give space for these extra windings the pickup was made physically bigger.
Interesting eh.
Oh, and the magnets have a different chemical composition, but that’s another story.
Pickup Repairs
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.

Hi there, just wondering if you know what metal the cover, or visible part of the pickup is made out of? Mine is quite rusty and was wondering if there’s a relatively easy way to do this, thanks.
Hi Alan, I can’t say for sure but an educated guess would be German Silver with Chrome plating. There isn’t much you can do about corrosion except replace the cover. Re-plating never looks right. These things are part of the natural ageing process of guitars.
