ALWAYS take any guitar you buy straight to your beloved trusted guitar tech. New or used every single guitar I buy goes striaght to my tech. Unless you have the proper files for the nut and know what your doing, don't go in there filing away. That's just crazy on a $2000 guitar. Hell I bought a kick around guitar for practice so I wasn't wearing out my main axe's a cheap Gibson/Baldwin 'Epoch'for $99 and it went striaght to my guitar tech for a fret dressing.
