Rhandy Rhoads, not even a difficult choice. He's my absolute first choice. He is without a doubt the most overall talented guitarist to have ever lived. Some of his stuff, especially his improv stuff, is just utterly mind blowing. I mean that doesn't even do it justice. His guitar playing skills were so profound and so unheard of that no guitarist has ever been that amazing. Before he died, he was studying classical guitar and was going to infuse it with electric. Can you imagine what he would have accomplished? Such a shame.
