OK, thought I'd chime in here..........SD Custom and the Cold Sweat are very different pickups-the CS has asymmetrical coils of plain enamel wire, the SDC is symmetrically wound with polysol.Secondly the ceramic magnet we use is way bigger so there's much more power on tap.A/B them side to side and tonally they're poles apart.
Dirty Fingers, well it depends if it's the original or reissue model but again it's polysol wound, symmetrical coils and 3 ceramic magnets, one in the centre and 2 flankers-totally different again to the Cold Sweat.
Incidently a SD custom shop pickup is marginally more than a regular BKP but one things for sure you'll have to wait a helluva lot longer for it and even then it won't be handwound.
