Worth,
Well, I guess you could call it official (beause he works for Korg, well maybe not, maybe he just has a shirt?), but I see it as a Korg guy shows up to one of their best stores in Italy, to show the Kornos & a little of the PA3X.

Not really an official product demo for everyone...so far there is none of those.
Thanks for posting it as it is one of the best, but that's not saying much.
