I just picked up a used Sheraton from Guitar Center. I know there are lots of fakes of Gibson guitars, but had not considered that someone would fake an Epi. I'm wondering how one can tell if an Epi is authentic? I checked the serial # against the http://www.guitardaterproject.org/epiphone.aspx, and mine seems to check out as far as the number. But the serial # isn't embossed, but appears to be printed on the headstock. Given that Epis are made in so many places, and there doesn't appear to be any one standard for IDing them, it just makes me curious about mine. Anyone know or have a definitive resource they can point me to? Thanks.
