I think that passive pot configuration with pickups is very crucial even if you don't use it. 250 K (and maybe 500K) pots are pretty standard and it colors pickup's initial sound to warmer, more familiar sound. Most passive pickups are designed having in mind addition of pots in signal chain. I think that DIMARZIO model P and model J will do the great job for you. (those legendary creamy colored pups, that come now in a black cover option).
GOOD LUCK
