I mean, can you take say 100 or 300 or whatever # of windings off a pickup (Tele, in the immediate case) and solder it back into working order? I don't see why that would be so difficult, although maybe there is some danger getting the cover off in a gentle fashion. Eh?

Certainly. I de-wind my P90s as supplied on Gibson guitars.<br /> <br /> Getting the covrr off the Tele neck pickup is easy. The difficulty comes in being very gentle with the coil wire because it is extremely delicate. This becomes a bit more difficult when the coil has been wax potted, so warm it up with a hair dryer to soften the wax before you start unwinding it.<br /> <br /> Look at a few YT vids about making pickups so you can see what's involved.

Thanks, Professor Goo.<br /> <br /> Perhaps we should start a business: Goobson Musical Products.

I have an ounce of (rather nicely fragrant) beeswax hanging around.

Yeah, it's pretty safe to remove the cover. Bend the tabs back all the way first, so you don't have to force anything, and warm the cover up a little to allow it to release from the bobbin. It should slide off with little to no resistance.<br /> <br /> You can warm the metal cover with a soldering stick. Use a little piece of aluminum foil over the tip of the stick so no solder gets on the cover. No need to get it hot...just warm so the wax potting releases and lets the cover come off.<br /> <br /> Best way to pot the pickup is to fully immerse it in molten wax, until the existing wax on the bobbin turns clear. You cam also do this with the cover on. Pure paraffin wax is too hard. Beeswax, surfboard wax, and (yes) wax from a toilet ring works great. <br /> <br /> Use a new toilet ring, or you'll sound like crap ;0)

My 65 P bass did not reject neon light buzz. I replaced the pickup with a Dimarzio P pickup when they first came out. The D & G coil never matched the E & A coil. <br /> <br /> Years later, I pulled the pickup out of my junk box and measured it. (I had learned a lot.) Sure enough, the E&A coil had far more windings. I removed wire from the coil until it matched the other coil. Noiseless and balanced. I used it on a Ripper bass mod, where I added it between the Ripper pickups.

So, if the neck pickup below is wound to 7.6 K, how many winds do I need to remove to get it to 7.2k?<br /> <br /> Thanks

Unwind about 75-100 wraps and measure that. Proceed the same way (unwrap, measure) until you get into the ballpark.

I'm afraid to get into the ballpark in case somebody bombs it.

I found on StewMac an article about wax potting.<br /> <br /> """For years, we’ve answered these questions with an online article about how the great pickup maker, Lindy Fralin, does it. Described in that story is Lindy’s recipe for potting wax: 80% paraffin and 20% beeswax.But the other day a customer emailed to say “Hey StewMac! Lindy doesn’t use beeswax anymore — he uses candle wax.” When I heard that, I called Lindy to get an update.<br /> It turns out Lindy’s done some new research, with the result that he no longer uses beeswax at all. He’s switched to paraffin, the petroleum-based wax sold in the supermarket for making candles and sealing jelly jars. He likes the fact that paraffin melts at a lower temperature, so there’s less of a chance of a coil being damaged by heat.<br /> <br /> Lindy’s other reason for ditching beeswax surprised me: he says beeswax darkens the tone of his pickups, affecting the sound in a way he doesn’t like. With paraffin, he hears a clearer tone with better highs than what he heard when using a mixture of the two. That’s interesting new information. Thanks, Lindy!""<br /> <br /> Huh...

He's some guy who won't mind his own beeswax.<br /> <br /> <br /> ""Look at a few YT vids about making pickups so you can see what's involved.""<br /> <br /> I did. Potting is to avoids air bubbles???????????<br /> <br /> Well I'll be danged........

""Unwind about 75-100 wraps and measure that.

I'd be lucky to tell 7k from 8k. So give us a guess, Oh pickupologists,: how many windings would have to be removed to lower the resistance from 7.6k to 7.2k, more or less? Eh?

I'd guess at about 350-ish. <br /> <br /> You need a better metre.
