This is guitar number 7 before it was strung up... this is a classical guitar (nylon strings). It is deeper and longer than guitar number 5 (below).
A patent is pending on the new bridge design, which is amazing in its simplicity, but allows radically new small guitar designs that have full-size guitar sound.
The simple mechanism is a lever that transfers the longitudinal motion generated from the strings vibrations, over the saddle, into lateral motion perpendicular to the guitar's soundboard. It also modulates the impedance of the vibration energy, changing it into a more useable force/distance ratio, and places it in a more beneficial location on the soundboard. This placement allows the whole guitar to be made much shorter, because the large area below the saddle is not needed anymore. On the guitar pictured, the soundhole has been moved up to the top of the soundboard, and some frets float over it.

A happy person trying it out at the Falcon Ridge Folk Festival.
