so i own a 2013 Gibson Government Series V and im getting this buzz that i have tracked back to my guitar as i ruled every thing possible out. Now whats happening with this buzz is its taken a lot of the tone out of the guitar but when i touch any part of the metal the buzz stops and the guitar sounds fine. I am pretty sure its a ground issue and would like to save some money by doing it my self, does anybody know how to diagnose and then fix the problem?
