Yes, it's a load of bollocks.

There are always people coming out of the woodwork with such snipes about long dead stars. Of course, conveniently, the stars are not in a position to put the record straight.
I got a good live track of Hendrix doing Stone Free. You can clearly hear him easily tune in a straight A major bar chord before he launches into the opening riff.
Also, being from the North East of England (Chas Chandler's home) I have heard from an old but very reliable sound engineer friend of Chandlers's that Jimi invariably tuned everyone else in the recording studio if he even so much as detected they were out....by ear.
I think our man on the radio is - sadly - trying to put a chink in a dead star's armour by implying the star could not even tune up. I have never, actually, known ANY good guitarist who couldn't tune up, let alone a phenomenon like Hendrix. As I said, a load of bollocks.
