peter hook? The man is an absolute amateur, an absolute lack of technique, feel, or originality. Jah wobble has only one bassline, but boy is it a good one. for my money it's got to be bernard edwards for sheer groove with bootsy a close second, then people like jonas hellborg and stanley clarke for taking the instrument in different directions. Mark king is way up there, he's an amazing sponge soaking up the styles of jaco, clarke, larry graham, and fuzing it with the melodic style of john mclaughlin. Despite being known for overplayed slap, his real gems lie in fingerstyle.
