Another thing to add to my previous post on this topic... I'm not positive of what kind of Strat you are playing... some Strats (especially Strat copies)come with pickups that aren't as sensitive. These pickups have a hard time picking up the higher frequencies of treble strings... If adjusting the height of the pickups doesn't fulfill your needs maybe look into getting some hotter pickups... (i.e. Texas Specials, Custom Shop '69s, SD hotrails...) Also check out the "Guitar Players Repair Guide" by Dan Erlewine... it's a great reference for anyone. It has info on stock Fender set-ups as well as set-ups of famous guitarists including Jeff Beck and Stevie Ray Vaughan. The set-ups include guides to pickup height... I think it would benefit you to check it out.
