when i purchased my bass, the salesman tried to get me into a $50 maintenance agreement. he said it would pay for up to 4 set ups. i asked how often that should be done and he says 4 times per year (season changes) this seems rather excessive. how often do you have you bass set up? what does a set up get you? i had problems with open E string fret rattle that i corrected myself with a 1/4 turn truss rod adjustment, (mia jazz) and have been adjusting my action the way i like it. when i check the intonation at the 12th fret (using a chromatic tuner) they all read slightly sharped. how much varience is acceptable or do you always move your saddles until intonation is exactly dead on. i guess that sounds stupid, but i just wonder how critical you all are about it.
