Here we have a very scummy 1972 Fender J Bass pickup sent to me for a rewind. The pictures don't do justice to the level of 'mank' here! Sweat reusted poles, enamel
insulation breaking down, the whole thing smelling of mildew ... bleeerrrrk.
The rubber cushion seems to have been stuck on with a compound similar to bitumen, and with age it has mixed its self up with the solder joints. Damn it smelt bad when I un-soldered the hookup wires!
Right, wire removed to show no tape on the bobbins ... or lacquer. The former definitely dates it to 1972 ... and helps explain why the pickup failed. After 72 the almost always taped the bobbins on JB pickups and they fail from shorts less regularly in my experience.
Most of the gunge removed from the bottom flatwork ... and here you will see the slightly projecting magnets which are the reason for the little spacer jig I used in the winding shot!
Here I've taped the coil to prevent the same shorting fault happening again.
The tape is sprayed with nitro laquer as 'belt and braces'.
Here is the pickup being hand scatter wound. The original was a very crappy machine wind ... it appears they didn't centre the bobbin properly, and all the early layers were built up against one side of the flatwork. A scatter wind will improve the tone anyway.
Wound
And now potted ... lightly in wax
And the job's a good'un!

looking forward to seeing the Super Distortion you rewound for me, not that I'm pressing you of course!

Speaking of correcting design flaws, is it possible to do a humbucker which fits in a Rick 4001 bridge pickup mounting without incurring the Wrath Of RIC? I've got an old Kent Armstrong (guitar mini-humbucker with bar polepieces, I think - original neck pickup from an Eggle Broadway) in mine that happened to fit perfectly after a little work, and sounds great. It's essential given the amount of fuzz I use on bass, but is another of the things RIC won't fix. Their humbucker is good in the neck but doesn't sound right in the bridge, it's too muddy - and too thin if you wire it in parallel.
