I am currently moding my SX SPJ-62. Ive replaced my capacitor, all of my pickups and pots, and shielded my cavities; it is sounding really good too . I have a badass bridge and would like to throw that on and get a good setup, but I do not feel comfortable filing the bridge or messing with the truss rod because Im fairly new to bass. Can anybody chime in with a shop that does quality work around the Nashville area? There are several places that I know of, but Im not sure who does quality work. I am aware that when it comes to setup / repair, the amount of money doesnt always correlate to the quality of work. Thanks in advance! P.S. I did a search and didnt come up with anything.
