Default Guitar body wiring and pickup query

Output was low.
Instead of owner tightening the controls which were all loose and

rotating
,
he started messing about with the pickup height posistioning and bridge
height.
EMGHz pickups , not these ones but I'm assuming they are ok as
proportionate
readings
http://www.emgpickups.com/content/wi...MGHZ-H1-H4.pdf
Bridge one 17.4K DC and 7.9H (1KHz) and fingerboard 7.2K & 4.0H
Looks as though the tone switch/pot turned so the 47nF body touched the
outlet socket forcing the bare lead of the cap against the grounded body
and
after that stayed touching. near enough, regardless of the where the
control
body rotated to next.



The switch connects the white and black seriesed tails to ground ,

rather
than left floating joined together in all those pdf graphics. What is

the
function of that option ? I thought electromagnetic noise nulling was

due
to
reverse windings in each pick up and then one pickup rotated 180

relative
to
the other.


Switching that point to ground shorts one of the coils, turning the
humbucker into a single coil pickup.



Gareth.




So given that these are made as humbuckers why would anyone want the option
to pick up more stray EMI and also get reduced output?
While at it any favorite ways to lock bushnuts. I intend double back-to-back
nuts on the bushes and moulding plastic mechanical interlinks between the 2
pots and 3way switch, to stop any future rotation. But where to find an
aesthetic thin nut for the 3way switch, the pot ones would be hidden by the
knobs.
It seems 3/16 to 1/4 inch fingerboard pickup heights between extreme
frettings of strings is a standard. I assume the bridge ones can be closer
though.
