Well, just wanted to start talking about this groove master since couldn't find a thread dedicated to him. And I think he deserves it!
Basically, there's something in particular that amazes me about him: Everybody talks about Jamerson's one-finger technique and how he could execute such basslines that way. Of course, that's a truly remarkable achievement, but I'd say that in spite of that apparently "limited" approach, his plucking hand looked like a real bassist's one. I mean, like someone who really knew what was doing.
On the other hand, Mr. Thomas' right hand technique is one of the most "unprofessional" looking ones I've seen:
Plucking the strings with his thumb while the other fingers were supported by extending them over the bass body. That's exactly the way in which most likely someone who doesn't know anything about playing bass would try to make some noises with it.
But don't misunderstand me. I'm not criticizing him. On the other hand, that's precisely what awes me about him. He's the perfect example of the fact that you don't need an ultra-refined technique to GROOVE. Not that I'd like to adopt his approach, but I really love and admire his style.
