the Norton is a great pickup! very underrated, a hiddem gem among Dimarzio's lineup for sure.
Roadstar's description and dimarzio's descriptions are spot on.
specs are really interesting -- 1 coil at 5k wound with #42 wire, and another coil at around 7.5k wound with #43 wire.
i sold mine, but only because i had a custom handwound pickup built to similar specs... sort of a "boutique" Norton.
also, the Norton design is similar to the "idea" behind the
seymour duncan 59/custom hybrids (which are also great sounding pickups)...
