Winding a humbucker with 40awg wire. Any thoughts?

Using TV Classics as an example, their bridge pickup has a DC resistance of 4.8k and an inductance of 1.8H, and the top of the filister screws, a Gauss reading of about 350. A typical Strat pickup by contrast, 6k resistance, 2.4H inductance, and flux density of 600 to 1100G at the tops of the AlNiCo pole pieces.Last edited by Antigua; 03-03-2018, 05:03 PM.

You can take your bobbin internal dimensions and run it through the coil estimator.
You will need Internal bobbin core length, width, height, and flange width diameter.
Using 50mm paf dimensions of 2.25L, .256w, 25h, .69 flange.
Aprox. 1800 ohms, and 3500 turns of 40S wire, .0035" diameter wire, per bobbin.
Up the bobbin height to .35"Height? (all other specs the same)
Aprox. 2500 ohms, and 5000 turns of 40S wire, .0035" diameter wire, per bobbin.
Those figures are at 90% TPL, near machine wind specs.
Keep in mind that normally as bobbin height goes up, the pickup becomes brighter sounding.
If you are building a guitar you can offset that by moving the bridge pickup further from the bridge.
IMO if the large wire, tall bobbin pickup is close to the bridge, like in a LP guitar, it will be at its brightest!
You can also try different magnets, like A2, & A3.
It will be interesting to see what you come up with.
Please keep us posted!

Maybe you'll end up with something that's good in its own right that the customer likes. I recently rewound wound a s/c bass pickup with 40AWG as an experiment and it came out at 3.8K. I was about to strip it off as I thought it would be disastrous, but the guy wanted to try it and used it on his next gig. He really liked it - he said it had a 60s Danelecro sound. When I asked about low output he said he'd never noticed anything and used the same settings he always uses.

Coil Estimator
IME large wire works for bass pickups?
Bass players usually like bright pickups.
Big wire, and tall bobbins = bright pickups.
Usually the opposite is desired for a guitar bridge pickup.
But, as with everything, YMMV!

Originally posted by Mick Bailey View PostThe original pickup was wound with 46 and the owner said it sounded like mud and wanted something completely different. There was plenty of room (I thought) and should have calculated it. My first thought was to use 42, but I had a spool of 40 right by me that I'd been using to rewind some reverb transducers and decided last-minute to see how that would turn out. In the end I had to fill the bobbin to get anything like a workable DCR. This is a lesson in doing the calculations before getting stuck in. As it turns out it worked really well, but it's not the right way. I would still have got a low DCR with 42 and would have ended up with more tuns than with 40, probably filling the bobbin just the same.
