Archtop bridge issue update--problem solved

I thought of that but I'm not sure they make a distinction during manufacturing at a low price point? Guess I could've looked at my electrics...

Thinking about it they probably do but ether way I think swapping G with B wouldn't make much difference and could give you some answers.

These kinds of issues are pretty tough to find sometimes. You probably really need a good tech who is pro at fretwork and setup if you don't get lucky and fix it yourself.

Keep us posted though. Curious.

Thanks to everyone who chimed in here, I really appreciate all the good advice. Here's how the story ends: I finally got the Epiphone to my local luthier. It needed a set-up anyway (120 gigs this year) and I explained to him about the buzzing. I just got it back today & it's perfect. The g-string buzz was evidently caused by the notch in the bridge, probably due to me using 13's on it where it had what I suspect to be 10's on it when I bought it around a year ago. The lack of sustain on many of the notes on the high-e string was corrected by him leveling the frets. He also shimmed the nut. So there you go. Thanks to everyone who offered suggestions.
