After reading the comments here, I decided to watch the video. I thought the guitars sounded great. And he can play. I didn't notice if he said anything disparaging about the guitars. He looked like he was having fun playing the guitars.
I haven't read the comments to the video on the youtube page, but I notice that there are well over 23,000 views.
So in a way this is kind of an example of a great player walking into a music store, picking up an Alembic, and playing for a while, having fun, and saying cool guitar!, and then telling 23,000 of his fans about this cool guitar that most of them had never heard of before. At the very least, he introduced some guitar players to Alembic. Maybe a few them run an Ebay search, maybe a few run a Google search, maybe a few surf into the Alembic.com site, and maybe a few end up here at our club.
So yes, he didn't bother to learn anything about the guitars before he picked them up; but knowing nothing about the controls, I think he probably introduced at least some of his audience to some really nice guitars.
I will add this caveat before clicking the post button; I don't play guitar. So I think the observations of the guitar players here in our club are probably more valuable than my own. I've also never watched any of the other videos in the series, so I don't know how this video compares with the others. He certainly didn't show off everything that Alembic guitars can do, but it did seem to me that he essentially picked up a really impressive looking guitar, said some really nice things about the way it looked, the wood, the adjustable nut, the bridge, and then plugged it in and played some really nice stuff on it, showing off the differences in tone that could be had from the switches, showing combinations of pickups, and having fun with it. It seems to me that there are at least a few more guitar players in the world who have now been introduced to Alembic.
I do hope that the belt buckle didn't meet with the back of the guitars.
