I recently bought an SS that was shipped across the country to my door. For the first week or so I was very frustrated not being able to get rid of fret buzz on my low E and A, especially near the nut. Had it set up and still the buzz. Not knowing what to do next I took the neck off to see if there were any shims, anything unusual. Nothing. And so I put the neck back on and ... the fret buzz is almost entirely gone. Nice strong, clean bass notes, as it should be! So I'm guessing the guitar was jostled a bit in transit...no hardshell for most models...and the neck was put just slightly out of alignment. Maybe the neckplate screws were a bit too tight or loose. I only tightened about a quarter turn after initial tightening. No need to be forceful. Sort of like a speaker, when you install a new one. Some will say your setup will be thrown off by taking off the neck, but I didn't have that problem. Be careful, of course, but if you've tried everything else, this may be a solution.
