That's a sweet looking guitar, with some nice looking wood, and the split inlays look great too! Unless you love the Phat Cats, I would put back the stock pickups. If they are the MHS pickups, they are some of the best Gibson has done in a while. And I love that they dumped the tonesucker varitone! One thing, I think a proper set of reflectors would look great on it too, ones that have an insert that actually reflects. Here's a set of nice non aged ones for a reasonable price.
