Thanks Flatop and steve.Since this is for "favourite" guitarists, rather than "best" guitarists, I can leave out Tuck Andress, and probably 25 completely anonymous pickers who got married, had kids, and stayed local.
Favourites? Joseph Spence, Estil C Ball, Tony Quarrington, Eldon Shamblin, Bob Dylan, Charlie waller, Doc Watson.
And the great Alton Delmore.
