My first bass tutor was actually a classical guitarist, Philip Booth, who as a person and as a muscian one of the most delightful people I have ever met. To me he represents a quality of musicmanship and skill that if I ever reach (doubtful) I would hope I would of done pretty well for myself.
Stevie Wonder to me is just amazing, great song writer.
Michel Camilo is again an amazing composer and player, and just flirts through styles with ease.
BUT OVERALL I think I admire musicians with a great sence of melody, melody always draws me whether its bass, keys, strings, orchestral...whatever!!!!
