I'm curious what kind of neck joint was used... traditional tapered dovetail? Like the tried-n-true X-brace, it's hard to go wrong with it, but the Alembic acoustic of my imagination could go a different route, in the spirit of innovation.
Re; slotted headstock, how about a (somewhat drastically) scaled-down version of Classico?
@hifi - I've had a thing for vintage Martin guitars for quite some time... it's fair to say, that's what put me on the road to here. =) I firmly believe the folks that founded Alembic are the C.F. Martin Sr. of their day, and the next generation(s) is/are following suit.
