Generally speaking, the differences should be mostly cosmetic...different knobs and, like @C Stone said, an all-maple neck with faux mother-of-pearl blocks and matching binding.
That being said, what I don't know is what kind of pickups are in it.
One thing I forgot to mention about 2013 was Squier's change from "Duncan Designed" pickups to "Fender Designed" pups. The difference in quality is debatable, since I've heard praise and scorn pointed at both, so it's probably best to consider them a matter of personal taste.
Whichever the VM '77s has, please chime in. I am, as always, endlessly curious!
