could be china but it looks identical to an EC maybe the same Korean factory without the huge ESP markups, Sperzel tuners, EMG/Duncans, tone pros bridge/tail, and earvana nuts.

They're made in Korea in the Epiphone factory and setup over in the US with the other US series Kramers. From what I've heard (and I've heard a lot,) they're amazing guitars. I'm actually thinking of checking them out myself. Here's a review from VintageKramer.com If you want anymore info on the Kramer Standard or Custom or anyother Kramer for that matter, check out KramerForum.com/Forum Those guy's will help you out with that no problem.

And btw- musicyo is notorious for pushing back dates like that, dont worry about it though they'll come in soon enough.
