Let's start from the beginning: why a headless?
I've always like the small and confortable guitars like Kramer Baretta, Washburn Steve Stevens and Nuno Bettencourt, and finally Music Man.
To have a small body the bridge should be positioned as close as possible at the end of the body. Consequently it must have a small headstock not to unbalance the design.
In a headless the bridge is placed at the end of the body to be able to easily access to the intonation adjustment, and the headstock is so small that you can't see it.
I've never been interested in the egonomic design guitars.
