I am currently moding my SX SPJ-62. I’ve 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 I’m 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 I’m not sure who does quality work. I am aware that when it comes to setup / repair, the amount of money doesn’t always correlate to the quality of work.
Thanks in advance!
P.S. I did a search and didn’t come up with anything.
