So let's take two regular humbuckers. Split them both leaving both north coils. The inner slug coils.
The problem is it won't be hum cancelling.
Am I right in thinking that simply flipping the magnet in one will make the slug coil south polarity thus making inner coils together hum cancelling?

Id say yes, and you would also swap wires on each coil to get back into phase |

White - Hot Black and Green together Red - Ground Yes, or, could do Red/White together as usual, but green hot and black ground. The difference would be whether you need to shunt the joined connection to ground or to hot to get the active coil you want. Slightly better to arrange things so you shunt to ground for coil cut, if possible |

I think wiring it as I said, grounding the two wires would result in the slug coil being active.
The same as with the regular unmodified pickup.

Am I right in thinking that simply flipping the magnet in one will make the slug coil south polarity thus making inner coils together hum cancelling? Strictly speaking, it would not. If the only change is one pickup's magnet flipped, the result would be the two slug coils are not hum-canceling, however the string-generated signals would be out of phase. To achieve hum-canceling, the wiring must be altered. The combination of magnet flipping and wiring alteration results in hum-canceling along with restoration of in-phase properties of the string-generated signals. Your suggestion of using white to hot, black&green as the series link, and red to ground as the altered wiring for the pickup with a flipped magnet, seems the most manageable choice. |

The wiring suggestion is not - that would select the south coil instead of the north coil when the magnets are not flipped - a good solution to get a humcancelling linkage without flipping a magnet - but it's then not the inner or outer coils. With the magnets flipped you would wire one SD the normal way (black = hot, red+white = split, green = ground) You would wire the other pickup reversed, i.e. green = hot, red+white = split, black = ground.

Hello Stephan. I disagree with your assessment. For hum-canceling you want to split to like coils when one pickup has a flipped magnet, because the connections have been reversed. Use both slug coils or both screw coils. For instance: Slug coil (Black-hot, White-ground) will hum-cancel with Slug coil (White-hot Black-ground) |

This is what my wiring suggestion will give, and it's the set up used in any PRS with the 5 way rotary or in any guitar set up for the John Petrucci wiring. Cheers Stephan |
