Looking for some advice on pickups. I own an American standard Fender Strat and I am looking for a more livelier pick-up setup but I do not want to lose that classic strat sound. Would I lose that classic sound by putting a single coil-humbucker in the bridge.

I also own an old Squire strat, my first guitar, with a humbucker in the bridge position. As being my "first" I cannot let it go and would like to use it again for the heavier music I play (Metallica, LP, etc.) but I need more crunch from the pickups. It has a humbucker and two single coils.

Any recommendations would be appreicated!
