Hi I'm having a new Fender MIA Jazz Bass Deluxe for the last year. Playing average of 10 hours per month not that hard rock style. I decided to set it up by myself after not being satisfied with so called "pro's" work. Neck relief was done according to the forum's directions, also saddles and intonation. I now find that at 5th fret on D string I have some buzzing. And still I think my action is too high. I consulted with guitar technician and he said that the NUT should be replaced and its height lowered and the frets filed and leveled in order to allow lower action. I am curious as this bass is almost new from Fender factory. It's also MIA Deluxe. I wouldn't expect the NUT to be changed nor frets leveled after only one year of normal play. What would you suggest in order to allow lower action and how do I get rid of that 5th fret buzz? Was technician suggestion logic? All replys will be very appreciated.
