Picked this up today,Got it for $320 with a hard case but it is a Epi case. Serial # says its a 99.Got it home and took it apart(it was pretty dirty)for some cleaning and discovered a crack in the nut,so I guess I will be looking for someone to replace that! While I have this tore apart completely is there anything you guys can recommend doing before I reassemble? Hopefully the pic shows up!
