Gigged with it in San Francisco on Saturday. Twice. I have to say, I really dig it. And so did the 3,000 people who watched us play. I got plenty of compliments on it.
The neck feels great. Aside from the nut feeling sharp and high, I can't really notice any discernible difference between this neck and the Gibson. String spacing, neck width, headstock size, etc. it's all pretty accurate. The body shape is only a little bit different, with the neck heel and the cutout being the only noticeable change. Also, I feel like the bottom bout isn't as round as the Gibson or my other Epiphone, but only by a little bit.
Sound wise, it's damn nice. The pickups sound leaps and bounds better than my other epi (no harsh, nasally mids,) and don't squeal like the ones on my Gibby. The pots have more usable range than either of my other two 'birds, but I have no idea if that means they used audio taper pots instead of linear taper pots. The sound is just a tad bit brighter than the Gibson overall, and drives my Ampeg just a little harder than the Gibson as well. But in fairness, I also haven't gotten around to messing with pickup heights yet.
In general, I really like it. I might even like it more than the Gibson I'm used to. It weighs less and has a slightly more modern voicing, but plays almost identically. For the price, I'd be hard pressed to think of a better instrument to buy.
