Jimi was one of the greatest musicians of the 20th century. Not only was he a complete master of electric guitar, he was also a pretty good bassist in his own right. He performed much of the bass work on Electric Ladyland, and all of the bass work on a little known disc called La Dorriella Du Fontaine. He wrote incredibly creative songs and lyrics, and made major contributions to rock, blues, and jazz. He was incredibly prolific, creating a massive body of work, mostly within just the four years preceeding his murder. I have almost fifty of his discs, and there are still hundreds (maybe thousands) of hours of stuff we still haven't heard, yet.
I'm not sure how you could compare him to a bassist. There are very few guitarists you could compare to him. Robin Trower is most frequently compared to Hendrix, but it hurt his career more than it helped it. Robin doesn't deny the Hendrix influence, but Robin Trower does Robin Trower. I've never even heard him do a Hendrix cover, and I've got everything by him, too.
I play a lot of Hendrix, but I wouldn't ever compare myself to him. Noel and Billy, maybe, but not Jimi. hrb
