The neck is one of the things I liked most about it, and where you can tell Mike Lewis wasn't just talking when he said they copied the specs of the original guitars : I used to have a '60 X175, and I have a '60 CE100, and the neck was extremely similar to those two guitars.
A fairly meaty neck, closer to a 50's Gibson than the baseball-bats Gibson sells as "50's necks" these days. Not thin at all, with a back shape that's somewhere between a "U" and a round "C", not too much shoulder so it doesn't feel huge or clubby, but certainly not thin or small - quite a bit bigger than the early 60's Guilds I have. The fingerboard, again like the Guilds of the era it was inspired on, is pretty round, a 9.5" radius with frets that are a lot bigger than the vintage ones. They're what Fender calls a "medium jumbo" these days, but my tech said "this is what used to be called jumbo frets". Frets are exceptionally well-finished for a brand new Korean guitars, and as far as I could tell, the nut was bone, and nicely finished too. A tiny little bit on the tall side, like almost any new guitar.
