OK Stu!
I too have an old Silva compass, but I doubt that it's sensitive to ectoplasmic energy or whatever ghosts give off. However it does point Northish. You know our magnetic declination has changed several degrees since we moved here in '76? So much for solid as the Earth... And, come to think of it, I have a couple degaussers from my R-R tape days. The RS tape one and a head one of some sorts. So I'm not totally magnetically bereft.
"Channeling the field was more important than actually shielding the field... And by channeling the magnetic field you could reap further sonic benefits ( and video ones too)."
I think "channeling" is the only operative mechanism in shields for non-varying signals. If you can effectively "short them out" then stuff on the outside doesn't see them. Varying signals on the other hand can also be converted to heat by resistive materials. Mu-metal does both. Actually all metals do to some extent but it does it by design.
Fun stuff. I was planning to do a lot more tinkering in retirement but I'm having so much fun just listening to what I have now that it's more curiosity than urgency.
