It's old news from Martin isn't it? At any rate, it's not a new concept, though the engineering might be new. I can't remember the name of the guitars from several decades ago that had a mechanical neck tilt adjustment, but I believe that Rick Turner (Renaissance Guitars) collects them. It's a good idea, even if the naysayers debate the acoustic purity of it. Taylor has a wedge/pocket thing happening these days, as another example.

I don't know whether I'd go for it, being somewhat suspicious of overly complex engineering in my axes, but it might gain a following among less (small c) conservative guitar buying public.

I'd like to take it apart to see what makes it tick.

Peace, Mooh.
