Well, I'm sure not everybody will agree with this list, but I hope that it gets a little closer. Besides, this list is made after my own musical taste and I'm trying also to put a lot of the names that most people can agree with. The first 20 guitarists are in order of importance, the rest of them can be put in any order, it depends on you.
