Two humbucker wiring and phase

[albacore]

Still got a bee in my bonnet about hamer humbucker wiring and phase. Hoping some experts out there will throw me a bone!

This one one ebay has some nice pictures of the wiring:

The dimarzios look original but seem to have 3 wires - black, white and bare - which does not correspond to the schematic that is in circulation.

My question is this: I have heard stuff about Hamers being wired out of phase for greater tonal possibilities but in this guitar both pups seem to be wired the same. Has it been altered or am I misunderstanding how out of phase works? If not achieved by the connection to the pots, is it done by reversing the coils or magnets? Or is the whole out of phase thing a myth?

Please help if you can as this is quietly bugging the hell out of me!

Most early DiMarzios didn't have multiconductor wiring; only the "Dual Sound" - a Super, otherwise - had it. REALLY early pickups had Gibson-style braided cable; towards the late '70s they switched to insulated two-conductor, shielded cable where white and black represented the start of one and the finish of the other coils, respectively (that doesn't look grammatically correct, but you get the idea), and the other two leads were connected at the coils. The bare wire grounded the cable shield.

So you always had series humbucking operation, but you could reverse the polarity of a pickup relative to another. I don't know if the pickups they made for Hamer in that timeframe were multiconductor - the ones they did for BC Rich were - but most of their "over the counter" models weren't.

Having said that, those pickups have obviously had the leads cut off right at the baseplate and new ones grafted on, so who knows what's been done.
