I seen a TV doc called Classic Albums: Electric Ladyland. It said Hendrix played a lot of the Bass on that Album including AATW. Noel Redding said he was pissed of with Hendrix cause he would let just anyone wander into the recording sessions of Electric Ladyland. He said he went into his Rec booth one time and someone was in it and they said ,"Who are you"......Redding said, Well I'm the Bands Bass player. He said that was it........He left Hendrix after that. Would be interesting to know for sure what songs Hendrix did play Bass on. All Along the Watchtower has some amazing Bass. Especially at the end. Also some other great Bass on that Album. I have no doubts that Hendrix could play amazing Bass. Not that Noel R ain't a great Bass player of course.
