I collected over 13 lists of the best guitarists of all time and combined them into a single meta-list. The results are below: every guitarist found on three or more of the original source lists, organized chronologically by date of birth. Because most of the “best guitarists” lists I found focused primarily on rock music, I also included lists of best blues, jazz, classical and fingerstyle guitarists.
NOTE: Just because someone is higher on the meta-list than someone else, it doesn’t mean he or she is necessarily better – it just means that one is on more “best of” lists than the other. Also, these are not my personal opinions and I have not even heard some of these guitarists.
For the same list organized by rank (that is, with the guitarists on the most lists at the top), go here.
