I know it's not new, but I never really looked into how it all works, until I came across this video:

Not too difficult to manage, and it's got every feature you could possible want. Neat! I wonder if they're going to update it with the new James Tyler Variax electronics.
I really liked the parker I played a while ago. I didn't immediately hate the neck on it, but the upper horn is awkward and the upper fret access is kinda meh. It was pretty awesome, but not $3500 awesome.
