Keeping in mind the OP asked about "favourite guitarists," not "best" or "greatest," I came up with this list. I've been a guitarist for 55 years, and these are the 10 guitarists I most enjoy listening to, if I haven't forgotten someone:
Jeff Beck
Jimi Hendrix
Jimmy Page
Eric Clapton
Pat Metheny
Jim Hall
Mike Bloomfield
David Gilmour
Steve Hillage
Andre Segovia
