Yngwie J. Malmsteen

In reality, he has one major flaw: he hasn’t realized that he’s a mediocre guitarist. But precisely from a technical point of view. He should go to a good teacher who can start teaching him a bit of scales, a bit of harmony, have him do exercises with a metronome and so on; otherwise, he will always remain a guitarist who knows how to play just one scale, on one chord, and out of time!
