@elessar: why it won't turn your strat into a br00talz metal machine, the way to get good hi-gain tones from a strat bridge is to rewire your tone pots to have neck and mid on the first tone and the bridge alone on the second tone, replace the cr@ppy ceramic cap by a PIO one (.022 works fine IMHO) wired Gibson 50s way (as Feline suggested), and roll down your bridge tone almost all the way down (the adust to taste). Tested on a '94/95 MiJ with Texas Specials, works wonder (and I'm mostly a HB guy).
Now a baseplate might also help wrt/ low-ends and punch, for sure.
My 2 cents...
