hi guys, im new to the whole world of pickups so i could use some advice. Right now im playing a fender strat ultra which has an ebony neck and a h-s-s pickup config with lace sensors( which i dont really like) and has a coil tap switch for the hum pup. i was thinking about putting coolrails or hotrails inthe neck and mid but wasn t sure what to put in the bridge. i was thinking a jb or custom custom maybe but im not sure how they would blend with the single coils. im mostly a metal head but i want a versatile sounding guitar so it doesnt get pigeonholed into certain sounds. 2 more questions: does output affect anything other than how loud a pup is such as say clarity? how do pots affect the pups and how would i know which ones to use? thanks.
