Ok, to keep it going 1,002 votes for Jimi, i thought i'd limit our choices to guys from 1980 to today. that's about "modern" times, no? at any rate, my picks are:
Robert Cray - made me a believer of position 2 as a "blues" tone. his phrasing is always fresh and original. and you've yet to hear amazing tone, until you've heard his dual Clubman 35 / 4x10 setup.
Doyle Bramhall II - ok, he's a near SRV clone like many guys, but still, he's not a bad song writer considering he wrote for the likes of Clapton, Allman's, Sheryl Crow, etc... also, his album, Welcome, has some choice tones.
