I understand the differences in sound, feel, etc between Strats, Teles, Les Pauls, etc. But I don't know the difference between a precision and jazz bass! I have a pretty poor ear for bass tones... It seems like a lot of my favorite rock bassists use J-basses, like John Paul Jones, Tim C, and Flea. Others use P-basses, like John Entwhistle and Nick Oliveri. Is one more suited to certain styles of music than the other? (Is "Jazz" a total misnomer? Seems like a lot of rockers use them.) P-bass pickups are humbucking, right? Does that make as big a difference as it does with guitars? ???
