The Who frontman insists his fellow bandmate is one of the most unique guitar players ever seen, so much so that Hendrix - who was regarded as one of the best musicians of his time before his death in 1970 aged 27 - adapted the way he played the instrument.
He said: ''Pete's guitar style - there's nothing like it. People say the best guitarists are [Jimmy] Page, [Eric] Clapton; yeah, they're fantastic, no doubt about it - amazing - but are they original?
''I would say they are derivative of Robert Johnson and all those people. But you hear Townshend with a power chord and the things he does with a guitar, which was copied by Hendrix, and it's totally original.
''You think, 'Where the f**k did that come from?' I think the real root of it came because he was a banjo player before he was a guitarist. Then you start to see that make sense.''
As well as Pete's different style, Roger admits he is ''really proud'' the group opted for a unique sound during the 1970s.
The 69-year-old singer added to NME magazine: ''We were trying to find the next thing to make a film out of; we wanted to be more than just a rock band, a bit like maniacs.
''You've got to dare to be different and that's what we did. That's one thing about us I am really proud of - we weren't generic; we were a thing on its own.''
