Hey! I'd just like to add some to this thread... I know it's a really old thread, but today I got to try a Babicz...
There was a show in Montreal where there were about 40 different luthiers... Well you can guess I checked them all out (some build really weird things!!) but 2 guitars really struck me there. There was a Babicz (which I REALLY had been wanting to hear for a long time), and a fanned fret acoutic...
Anyways, back to the Babicz, I have no idea why, but that thing actually works. This guitar was really alive. Sounded clear and VERY articulate! Like... I could play a chord and then stum a few strings and they would ring out really clearly.
Also, it was extremely dinamic. It didn't sound the same at ALL depending on how hard you played it and if you fingerpicked, etc. I really liked the change compared to a lot of acoustics...
Also, the neck system of his, it's really weird idea, but pretty cool. Basically, his neck is movable in a vertical direction with a single bolt, and while the strings are still on. The reason, he said, is that you can have perfect action without adjusting the saddle and stuff like that (I.E. You could use it as a slide guitar and then in 2 minutes have a regular guitar ready). It also seems that the guitar sounds very different depending on the height of the neck...
And btw, I saw a picture of the bracing he uses... There's almost none, or at least not for countering string tension (only 2 braces, actually (plus some for where the strings are anchored...))
Anyways, I just wanted to revive that thread because I was really impressed by the guy's ideas and the sound of that thing... (I was really sceptic before trying it, btw.)
