I just recently put a Hot Rails bridge model in the neck pos. of my strat and it's great. Fat and warm, but nice and tight on the low end and without losing any articulation! Great for metal soloing.
I have a Hot Rails bridge in the neck position of a all maple Carvin Dc127T along with a JB uao5 in the bridge.
The Hot Rails is fat and great for soloing. I've got the HR wired for coil splitting and it will do a decent clean chord picking when split.
