everything is in the winding.
two on the outside identical pups can sound like night & day once you plug em in
talked about diferent voicings with steve made possible with just winding.
example: ibanez powersounds are machine wound exactly straight. thats why they sound like pure cr@p. custom and butique pups wound by hand utilise scatterwinding quite a lot and emphasize layering of winds throughout the bobbin, making diferent voicings, mid humps, trebble bumps and bass tightness possible
(no, i didnt talk about this wiht steve from BKP.. it was Steve Vai ;))
