OK, so much for the philosophical point of view...things got from "favourite" guitarist to "best" guitarist in a quite subtle way. (You can't criticise people for their favourite guitarist)
well my faves are:
Jimi Hendrix..he's the reason I picked up a guitar Andres Segovia Joe Satriani Paco De Lucia Eddie Van Halen John McGloughlin Al Di Meola Pat Matheney Jeff Beck
Countless others who in one way or another inspired me.
