Again I tried not to show any genre preference and made sure every genre has a representitive or two.
Lists with metal and prog guitarists usually neglect punk and alternative guitarists, and vice versa, most of these are subjective, so I tried to do the most fair list I could.
These lists also tend to be skilled based, for me that's a small part of the criteria. But influence, impact and popularity are also very important, however I won't confuse popular artists (Billy Joe Artmstrong) with popular guitarists.
