Jaco, Dave Holland, Claypool. Robbie Shakespeare. Sting (compositionally). Cliff Burton, Geddy Lee, Entwhistle, Flea, Peter Cetera (don't laugh), Bootsy Collins, Tony Levin (all The Stick vs a traditional bass is debatable). Tom2k of Rage and Audioslave I've always dug his parts/sound, but isn't THAT good a bassist. Stanley Clarke. John Patitucci, and Andy Rourke (Smiths).
Great list and I feel exactly the same way about the guy from "Rage".
