Hey, im not ripping on strats, sorry for making you think I was... I am a strat man myself and my favorite guitarist is Yngwie Malmsteen... You can oviously shred it up on a strat, im just sayign that if you have played a guitar designed for lead playability you will noticed hwo much easier it is to play. Strats where designed in the 50s and came out in 54, they were designed for playability of what was being played back then... rythm stuff, and blues. Not 3 note per string shred. Thats why a strat is "the" ideal chording axe, but not so much for shred.
Keep in mind that most of the guys that do shred up the strats have em modded (im not saying you cant shred on a stock strat, clearly you can). Yngwie's got the scalloped board, which alows you to develope lighter touch which really does significantly increase your accuracy. He had larger frets, and I think with his re-fret, the fretwire is a different radius than stock fretwire, therfore changing the radius to probably a flatter radius... that is... if he didn't choose the same radius fretwire his guitar had before (7.5). He also has a replaced not which could vary the radius.
