It's all in their touch, so I know I'll never get anywhere near their tone. I did check out a picture of Stanley Clarke playing and I saw that he glues the transducers onto his bridge. Thanks for the input Ric.
Yes, it's all in their touch.

I do find it interesting that you (Jazzcat) mention the sounds Charlie Haden and Stanley Clarke get because I find them generally to be quite different.
Much of the sound depends on the bass itself and how it is setup, although experienced players often get 'their' sound on different basses.
I'm with Ric. If you have the opportunity, put a Full Circle on the bass and that may go a long way to helping you get a usable sound.
