That is pretty slick there Ken and Jeff. I mostly only read about and look at these contraptions, (you know the alternate 5-string universe thing) and this is one of the cleanest looking one's I've seen. Nice design work. I really like the shape of the fingers or cleats or whatever they should be properly called. Someday I will have to play with one just to see what it's like.
In terms of function, does one open it up a half step at a time depending on need? I know I've seen a few different designs but was never really clear on how these are different. So a little bit of educational discussion is hopefully encouraged.
