I own several Epiphones and, occassionaly, have run into a fret buzz issue. It's not a major problem because with a little tinkering, whether by my luthier or myself, it goes away. First, agree with the posts on changing out the strings for the heavier guage. When your strings are off, you can do the 'rock' test. Also, at that time, you might want to 'tap down' each fret wire. Seems Ephiphones have a fret wire issue (especially, if they haven't been humidified properly). It's a quick fix and worth the extra effort. Of course, proper tools and or experience is a given, so, head to your luthier for this if you don't feel comfortable doing this. Finally, a proper setup will be needed, especially, taking into consideration your personal playing requirements. Remember to properly humidify. Here in Arizona, it's critical. Good luck.
