  • Single coil polarity question? | The Gear Page

    Feb 02, 2008· Unless the magnetic polarity is also reversed, the pickups will then be out of phase. You cannot have both hum cancellation and in-phase with the same magnetic polarity. Not knowing the winding directions of the pickups coils in question would be a consideration as the magnets themselves have nothing to do with hum cancellation.
