Changed polarity (silly newby question)

Grounding magnets has not really caught on yet. I have a feeling most manufacturers can't be bothered or can't figure out how to do it reliably. It will reduce induced noise so it's important in my book. I can't tell you what the capacitative losses would be between a hot start and the grounded magnets. I don't worry about that stuff just yet.

I had a Fender Deluxe P bass here to install one of my Neo Jazz pickups at the bridge. The neck pickup was a stock Fender P.

I was surprised how much noise the P made when you touched the magnets, and even without, it was a little noisy, and that was all the high frequency type of buzz. So I disconnected the common from the pickup which was attached to the brass shields under either coil, and ran it to ground, and also added some copper tape under the magnets and grounded that. It was nice and quiet afterwards.

Anyway, if you are winding a single coil and the magnets are grounded, I'd make the start ground too.

Well, next PUps will be this way, but ground magnets does change tone?

Another question a little off topic, tape rods in single coil, dont will prevent to the wax to flood the inner part of the coil?
I had put teflon this way in one PU, (it is not a fancy PU I now, vulcanised fibre are coming) this prevents contact with wire, and let wax flow.
