Basic Question

and so

Another is it removes the "noise antenna" from the center of the coil. When the magnets are ungrounded they tend to pick up much EMF and RF noise, grounding the poles helps quiet single coils significantly. The tough part being how to get a good connection on AlNiCo magnets which are non-solderable.

Did you find doing this worth while? Does this eliminate noise that proper cavity shielding misses? Tks.

I was experimenting with it and also other ways of shielding besides "proper" cavity shielding. I've long been suspitious that glueing/sticking copper shielding into the cavity's "might" be damping some of the guitars natural wood resonance, so I'm always on the lookout for alternatives to adding copper (and other) shielding to the guitar's body.

For instance on a Strat it would be nice, if, just as the electronics were self contained on the pickguard/scratchplate, it would be nice if that assembly also provided the necessary shielding/noise-measures too w/o any additional mods to the cavity.

Nordstrand grounds his magnets with a thin strip of copper foil over the bottom, overlapping the edges of the magnets followed by a second piece of flatwork with holes for the magnets that keeps the pressure on the copper for a better contact. It's not as reliable as my method, I just spray the bottoms of the flat work after the magnets are charged with supershield. The nickel particles cling to the magnets until it dries. Copper tape over that and solder the drain wire to the tape. Hot wax has been a problem for the copper tape so I mask the bottoms with the heat proof tape and spray after the dip.

The term "Super Shield" is used in almost every area of human endeavor; some I would not have guessed; others are more obvious. Is this the one you mean? (available, for example web-tronics.com)

When I give away my closely guarded secrets I like to make things just a bit obscure. Yes that's the stuff, we've talked about it many times here so I imagined most folks would know what I was blathering on about.

Thanks, David.

OK, guys. Today, I changed the way I wire. My starts are now ground and ends are now hot.

Ok, so now think about this: if your end is grounded your coils are self-shielding.
