I bought my beautiful Fender Jazz (U.S.) last month and it's time for a setup and adjust. Should I buy new strings for the intonation setup and what would be the optimum height for the strings? I do play all over the neck with lots of diffrent sytles of music. I have been known to be fairly aggressive in my attack on the neck. Other than the obvious what else should I be asking the guitar tech. to look at and adjust? This is my first Fender Bass so a bit of a newbie with these guitars.
