Upgrading the stock Casino pickups for a more vintage tone

I recently ran one of my regular competitions to wind a set of handwound pickups and the winner, Mike, asked whether he could have his Epiphone Casino pickups rewound/upgraded for a more vintage tone - "No problem", I said.
The stock pickups had a very high output, 12.1k in the Bridge & 11.6k in the Neck, an unsubtle set especially for a Hollow Body guitar. Mike wanted to tone them down with a rewind and new magnets.

The first task was to remove the covers and see what's inside. The Epiphone Casino has custom bobbins with a string spacing narrower than a standard P90. The option was to either make new bobbins to match the cover pole spacing or simply use the existing ones. Mike had no issue with me utilising the existing bobbins so the challenge now was to remove the existing overwound coil wire in such a way as to not nick the sides. Any cuts or scratches to the very thin top & bottom layers of the bobbins could catch on the new coil wire when winding, snapping or pulling it leaving a few thousand turns of coil useless.

Whereas the stock Casino Pickups had a high output, probably due to the thinner 43AWG used (perhaps by mistake), Mike wanted a more vintage tone with a lower output set. I re-wound the coils to a more manageable 7.9k in the Bridge & 7.2k in the Neck which when coupled with my custom made Alnico 5 magnets, would give Mike the brighter P90 tone he was after.

With the new coils wound, the new magnets in place attracted to the pole screws underneath, the pickups were ready to be rebuilt and wax-potted. To stop any unwanted microphonics, I always securely fix the magnets to the underside of the bobbins and wax pot the pickups with a mix of 70/30 ratio paraffin & beeswax. Beeswax isn't always used in wax-potting - I recommend it though as it makes the wax less brittle and therefore less susceptible to cracking which could, in some instances, damage the delicate 42AWG coil wire.

After cleaning off the waxy residue and a quick polish & test with the multimeter, the pickups were ready to be hooked-up to my test guitar just to make sure they were ready to send back to Mike. He received them, wired them back into his Casino guitar and sent me an email back:
Great stuff. Thanks so much!! They're a massive improvement! I'm not generally a P90 guy, but they sound fantastic. That syrupy Another Brick in the Wall solo tone is just right there.. :D
