Buenas. I have a '97 52RI and a '99. The '99's bridge pickup is brighter and thinner sounding than the '97. Sounds a little more like a 60's-70's tele. I recently got a nocaster bridge pickup here in the garage sale (thanks s.m.), since I always wanted to try one. I tried it out in the '99 and it sounds alot like my '97 52RI. Not exactly the same and the nocaster isn't microphonic (yet?) but they're kinda close. The '97 and '99 52 RIs are more differenter. just shows to go ya.
