I tried an MIC Epiphone Les Paul standard and a Gibson Les Paul standard on the same day, but I won't compare tone because they were used on different amplifiers. But personally, I found the Gibson's playability and quality to be top-notch and superior to the MIC Epiphone (of course), but here's the catch. The MIC Epiphone wasn't far behind. I liked it and would spend the dough to bring it home if I had the dough.
In my opinion, its more of a consistency problem that Epiphone's China factory has. The same problem Ibanez's China and Indonesia factories also have - consistency. There are some excellent pieces, and there are lemons, but there are quite a number of lemons, so you definitely have to find a good piece, because there are bad pieces that somehow 'pass' the quality test of their factories. Don't ask me how. :mrgreen:
