THEWIZARDOFAZ!!! Blueshawk dummy coil question???

[berlinbetty]

  Or anyone can anwer this if they know, but I saw the wiz has a page on this one...http://www.wizardsofaz.com/guitars/blueshawk.html

  I'm wondering how the dummy coil can cancel (or "cut back" as you say) the hum of both pickups?  With my limited knowledge of dummy coils (there's hardly any info on the net about them) I'm figuring that the dummy coil is RW like the middle pup on a Strat, but then in the middle position the dummy coil is taken out of the circuit so the two pickups cancel each other out which means the neck is RW to the bridge therefore making the windings in one of the pickups the same as the dummy coil.  Or not?  I guess my question is how the windings of each pickup are configured, if you (or anyone) happen to know...

  Let me know if you don't understand my convoluted question...

  Hmmm, this is very interesting.  Seemingly, two pickups together don't have to be RW/RP to be hum-canceling!  If I'm reading the Pickup Orientation paragraph correctly, the two pickups aren't reverse-wound, but reverse-polarized and this alone is sufficient in eliminating hum!
  Now that I think about it, stacked pickups are the opposite.  They're reverse-wound with no reverse-polarity, two sets of windings-one set of studs.
  I thought you need both RW AND RP, but apparently, you only need one or the other.

  Yes?  No?  Comments?
