Paul Gilbert was Buckethead’s teacher back when Buckethead was in his early teens. Amazing player, not just a shredder. Sorry for the late post. I was getting tired of the politics so I searched and found this thread. They say BH can play 20 notes per second.
Buckethead was really good. I remember when he rose in fame and everyone was trying to figure out who he really was.
Another shredder I would add to the list would be Chris Impelliteri. The song “Stand in Line” with Graham Bonnet on vocals was killer.
