I think that is an accurate assessment: With Hendrix it was the whole package. It's not like there weren't technically better guitarists around at the time (most country pickers probably), but no one had melded with an electric guitar like him before and no one was as daring and daunting. But Blackmore's tone, his penchant for delaying notes and then rushing into something fast, his stage demeanor and songwriting (many riffs), an especially blatant example here,
was full of Hendrixisms. Even the change from his beloved ES 335 to the Strat was a bow to Hendrix. Where Stratocasters had suffered from a Hank Marvin & The Shadows uncool image in early sixties Britain, the kid from Seattle made the Strat sexy and dangerous as well as the iconic axe for coming guitar heroes.
Where they differ is that Hendrix had that sexual, frenzied inspiration thing with his guitar, Blackers' soloing is more cerebral and refined artful or simply just clever. It was Don Airey who played with him in Rainbow (and who has played with guitar heroes such as Gary Moore, Michel Schenker, Uli Roth, Steve Morse and Randy Rhoads to name a few) who once commented along the lines of: "Ritchie thinks too much about his own playing to be truly gifted, to be a force of nature like all those other players, he is his own production, but a mesmerizing one."
