I've had one, with Jackson-style headstock. Mahagony body, maple neck, ebony fingerboard. Two passive humbuckers wired VVT.
Quality-wise it was good, but not stellar. I've expected more from a Gibson with a "Custom shop" label on. No shielding, wiring could be better. Bridge somewhat odd to adjust.
Was not my cup of tea, but played nice and sounded good pickstyle. Fingerstyle not so good, though. Traded it away to some guy who plays death metal with a pick, he was quite happy. Massive, thick sound, pointy and all black, what's not to like?
Sounded well with his band, too.
Looked like this.
