I’ve never knowingly listened to any of Yngwie Malmsteen’s guitar playing, nor do I know why the scalloped frets were important to him. I do know, however, that there is always a place for a nylon strung guitar. I don’t have one at the minute, and I don’t think this’ll be the one for me- though I do really like the idea of a nylon strung Strat with a whammy bar.
