I got to play one the other day at a "Tone Made Easy Event".
I'd say the neck is very strat like, it was a matte finish and felt great to me (for full disclosure, I'm 6'4, and have large hands but they aren't crazy bear paws or anything like that)
The store that had the demo also had a jtv59 & 69, so I went right over after playing the standard. I'll say the 69 felt slightly thinner to my hands after playing the standard but not by much. And of course the 59 was a completely different beast (still felt nice, but a pointless a/b test).
I'll say this though, I preordered a standard by the time I got back to my car. The JTVs felt great but the standard felt "right" to my hands. Of course ymmv.
