I have owned 20 basses. Mostly P basses and a few Jazz. 95% American. I have never had one with this poor a set up. The truss rod does nothing. I can loosen it up completely and I still get buzz on 2nd fret. I have to raise action so high using bridge that it is not comfortable to play. I tried shimming neck (I have never done this before) with business card stock and had similar results. I got rid of buzz but action is crazy high. If I bring action down with bridge it buzzes. I tried shimming nut and still buzz. Neck must be so stiff as truss rod does nothing. From as tight as I can make it to full loose tune or actin height stays the same. I have a Squire P that is superior. Any suggestions?
