I bought an FSR Jazz last month from GC, and as I have played it, I have found I have several dead spots in the 1st octave of my E and A strings. I understand they frequently get them on the G, but this sucks being down where I play all the time! Is this something that would constitute an exchange at GC, or do I just need to replace the neck? I wanted to get your opinions before I call them and look like an idiot. Thanks!
