I have two 2012 MIC Epiphones that I believe are top notch instruments. Fit, finish, playability. The quality of the pots and such leave quite a bit to be desired, but you wouldn't notice really unless you went in to do a pup change or something. Speaking of pups, IMO the ProBuckers and Alnico Classic Pros are VERY good.
I did change the pups in my Epi LP but that was because it sounded too close to my '99 B7. So I put some P90s in it ;)
The Ultra-339 is great as is.
Now for the bad news. I've been to 3 different GCs since the beginning of the year. I always grab either an Epi LP or an Epi 339 or similar to check out amps with since they are what I have at home. I can't believe the number of these that either don't work or that have loose hardware as they're hanging. When I mentioned this one time, the GC dude told me that 8 out of 10 Epis come in like that. He was either telling the truth, or these guitars can't stand up to being tried out.
At any rate, I'm very happy with mine. I don't think there is a better *value* guitar out there. Just check 'em out carefully and make sure you get a good one.
