I'm trying to find a good set of pickups to upgrade my strat, I was thinking the hot rails, but I heard about cool rails, whats the difference? I don't want active pick ups. I'm just looking to keep the strat sound just have the comfort of humbuckers, elimiate hum and add a little more balls to the sound.
You could rewire your pickups for series and parallel combinations and properly shield it to get rid of hum. Then you'd definitely be keeping the Strat sound, it'd be hotter, it'd be cheaper, and you'd have more tonal versatility.
