Are All Humbuckers Splittable?

You can split two humbuckers simultaneously by the same push-pull pot. As soon as you pull up, both humbuckers split at the same time. If you want independent control over your humbuckers, you need to use two separate push-pull pots, one for each humbucker.

Can any humbucker be split?

Any humbucker will work.

Any standard size humbucker, such as the Dimarzio Super Distortion, Seymore Duncan Pearly Gates, and the EVH Frankenstein can use this mod. Any mini-humbuckers can use this mod. They can be side by side mini-humbuckers like the Seymour Duncan Hot Rails, or the Lace Mini Nitro.

Are humbuckers magnetic?

Humbuckers work by pairing a coil that has the north poles of its magnets oriented "up" (toward the strings) with another coil alongside it with the south pole of its magnets oriented up.
