Ricksy is confused.
Eddie\'s \"contentless spam\" came from one of my posts.
Eddie has never contributed anything to USENET, except when he got spanked
in the electronics repair group.
https://groups.google.com/g/sci.electronics.repair/c/MesPLcGU4BE
Hurt Eddie is taking that out on USENET.

Not so fast. A classic source of widespread hum fields is wiring
errors or failures in the power wiring of the venue.
In the US, ring busses are not allowed, so out and back currents are
close to one another, and their magnetic fields largely cancel. Unless
someone reversed power neutral (white wire in the US) and safety
ground (green wire). Which I have personally encountered.
War story: I\'ve also encountered broken neutrals in 240 Vac
split-phase (+120 - 0 - +120) power cables. I was attending a summer
stock play (where my kid sister was acting) held outside on the
grounds of a local school, as the light of day faded, I was looking
idly at the stage lighting, and noticed that some lights wee too blue
and other were too yellow. These lights are incandescent. Hmm. After
the play, I approached the Director and asked him if he was having
problems with things blowing out. Stunned look ... how did you
know??? Told him of the too blue and too yellow lights, and that this
implied a broken neutral. He was very interested. So we went along
the main feed cable, opening Edison connectors. We quickly found one
with the neutral completely un-connected. Director was *very* happy -
he would have had to pay for all those brand dearly-departed new
electronic dimmers. But it was the rental company\'s fault.
As for ring busses, which are allowed in Europe and I assume
Australia, while if both rings are intact, magnetic fields will
generally cancel, all it takes is a single ring break to force
significant currents to take the long way around.

Yes, that\'s true these days.
I did find the patent I mentioned above. It\'s US 7,259,318 to Illich
Chiliachki of California. The patent is now expired because later
maintenance fees were not paid.

The bane of many poorly shielded electric guitars .
The remedy for capacitive injection was to electro statically shield
the routed cavity, originally by carefully fitted brass foil shielding
tubs, then (after I arrived) by nickel-dust based shield paint sprayed
thickly on the walls of the cavity. The DC resistance between any two
points on the cavity wall was about 20 ohms. The underside of the
pick guard had an aluminum foil layer glued on. These shields were
all grounded to the shield of the coax wire from guitar to amp. The
strings were also grounded.
The remedy for magnetic interference, chiefly at power frequencies and
harmonics, is various kinds of humbucking construction.
** All these things were well known and adopted by makers like Gibson in the 1950s.
But they were a luxury brand sold to professionals.
A radio repair man called Leo Fender began making similar things, very cheaply.
https://en.wikipedia.org/wiki/Leo_Fender#Early_life
That\'s my understanding too.
Working at a time when triac dimmers were unknown and likewise safety earthing - he gave almost no attention to ES shielding.
His famous Stratocaster guitar has only a token effort at such and is a first class receiver of hum and buzzing from the AC supply.
Nearby fluoro lighting drives one crazy.
https://insounder.org/under-hood-9-evolution-stratocasters-electronics-wiring
Note the use of plastic covered pickups, unshielded wiring and no cavity shielding at all.
Fender relied on the player earthing themselves via the steel strings to proved any measure of shielding.
AFAIK even recent examples are little better.
All true.
The instrument is considered to be is \'\"sacred\" by players and must not be changed.
Also true.
One thing that people do is to put a larger coil in the bottom of the
routed-out tub, and use that to humbuck the old-school singlecoil.
With good ES shielding and grounding of everything, this can help a
lot. There is a patent on this, but I don\'t recall the number
offhand.
** There is no huge problem with players standing a few metres away from any AC transformers in the vicinity.
The mag field from an AC transformer is purely short range.
The need for humbucking PUs arose from those who sit next to or even on top of their amps.
Not so fast. A classic source of widespread hum fields is wiring
errors or failures in the power wiring of the venue.
In the US, ring busses are not allowed, so out and back currents are
close to one another, and their magnetic fields largely cancel. Unless
someone reversed power neutral (white wire in the US) and safety
ground (green wire). Which I have personally encountered.
War story: I\'ve also encountered broken neutrals in 240 Vac
split-phase (+120 - 0 - +120) power cables. I was attending a summer
stock play (where my kid sister was acting) held outside on the
grounds of a local school, as the light of day faded, I was looking
idly at the stage lighting, and noticed that some lights wee too blue
and other were too yellow. These lights are incandescent. Hmm. After
the play, I approached the Director and asked him if he was having
problems with things blowing out. Stunned look ... how did you
know??? Told him of the too blue and too yellow lights, and that this
implied a broken neutral. He was very interested. So we went along
the main feed cable, opening Edison connectors. We quickly found one
with the neutral completely un-connected. Director was *very* happy -
he would have had to pay for all those brand dearly-departed new
electronic dimmers. But it was the rental company\'s fault.
As for ring busses, which are allowed in Europe and I assume
Australia, while if both rings are intact, magnetic fields will
generally cancel, all it takes is a single ring break to force
significant currents to take the long way around.
> As it happens, nearly all humbucking PUs have full ES shielding too, so are dead quiet.
Yes, that\'s true these days.
I did find the patent I mentioned above. It\'s US 7,259,318 to Illich
Chiliachki of California. The patent is now expired because later
maintenance fees were not paid.

Yes. I don\'t know when the transition happened, but it had to be
gradual.
