On the "Electric Ladyland" album, Hendrix didn't play bass, of course, on "Voodoo Chile." As is well known, Jack Casady did. But he did play bass on over half the songs, the exceptions being Crosstown Traffic, Little Miss Strange, Burning of the Midnight Lamp, Come On (Let the Good Times Roll,) and Voodoo Child (Slight Return,) all played by Noel Redding. Also there is one song on the album that doesn't have any bass, although I can't name it at the moment.
Often when he would end up playing bass somewhere--like unannounced at a club--I think he did it mostly as relaxation. After playing music all day in a studio, he would relax by playing even more music. In the early days when Noel Redding would accompany him, sometimes Noel would play guitar and usually Hendrix would end up playing someone's right-handed bass upside down (as noted in the first post.)
