... sounds to me like a neck angle, or possibly relief, issue as well ... Truss rod adjustment may actually be what's required. I notice Kwak has "paged" Freeman Keller - he seems to be a wealth of information on guitar setup and tweaking. I'd wait for his opinion as well. Alternatively, you've probably noticed his "sticky" entitled "Is my guitar sick" ... some useful tips might be found in there.
Good luck !
