Watched him do a performance on PBS ;last night...it was a birthday tribute to the memory of Les Paul. I have never seen a guy get that kind of sound out of an acoustic guitar in my life before. (it was an amplified Gibson 6-string acoustic....but obviously he was running it through some pedals, heads and gear) The end result was something Jimi Hendrix would have been proud of.... He did a couple of Hendrix covers......."Voodo Chile" and "Red House".......he also did Mountain's "Mississipi Queen"... Blistering stratospheric runs in every song he played. Don't know how old this show was.........but it blew me away watching and listening to him and the band.
