I admit, I know nothing about them. Just went to their website, and frankly, it looks like a bit of a gimmick. No where is a satisfying answer to the question "Why aluminum?" The best the site seems to say is, "Because it's not wood!" Although the comic book/CD press kit at NAMM was clever, I see no reason for that approach except to attract attention. May be nothing wrong with that, but there really should be some substance behind the flash, and I am just not seeing it. On the "Press" page, I didn't see much (actually, I didn't see any) lavish praise on how wonderful the guitars sound in the 2 or 3 paragraphs shown, just things about sustain, and mostly about how innovative it is to make archtops out of aluminum. If a hand-picked group of press clippings can't say any more than that about how those guitars work as "guitars," (not curiousities,) than I think I have seen enough, for now, at least.
In other words, the jury is still out.
