Yeah. But there is a difference between the electric out of phase and magnetic out of phase. I suppose the differences cannot be heard, yet on 2c (braid wire) HBs using the ground for the hot wire makes the signal open to outside interference, which is not an ideal situation. The same kinda observation holds also for tele pickups with a baseplate (or cover) as the ground wire (black) is soldered to the baseplate (cover) as well.
That is irrelevant on 4c HBs (just ground black instead of the green), and strat s/c's without the baseplate. I suppose that's what my buddy Artie was talking about. No?
