SRV was definately innovative. Playing blues in minor E and minor A family chords, and playing it progressively had not been done before. Hendrix dabbled in it, but SRV cleaned it up and made it an art.
You may be wrong on this.
SRV used to jam on Sundays with Gene Ramey, he of the electric stick and the Charlie Parker Quartet. Used to watch Ramey at his house with both Vaughn brothers and other Austin jazz and blues musicians basically schooling them on bop and Kansas City style.
Ramey probably had a greater impact on SRV than Hendrix.
SRV never even approached the greatness of Jimi in either in innovation or just flat-out blues jamming ability.
