A How To Guide on Bass Guitar Setup - Setting Truss rod, Action, Nut, Intonation etc

This video was good and thorough! I have set up my bass before but i think with help of your video i can get it better.
My bass is sad one though, it has crooked neck which forced me to do fret grinding to it and quite a bit. Recrowned all the frets aswell. Fret buzz makes me crazy. People say basses are meant to buzz but really.. are they?
