The  90 degree x braces are not unique, several builders use them, but ours  do not extend to the sides. They are carved to airy thinness 2 inches from the sides to free the soundboards vibrations.   The outside perimeter of the soundboard is the main source of generated vibrations.  The top is also 1/16th on an inch thinner around the entire perimeterof the guitar to further increase vibrations to a maximum level.

In addition to a one piece mahogany neck an upgrade to a 3 or 5 ply laminated neck is available. The laminated necks are made of various woods.The laminated neck is a stiffer neck that transmits a brighter tone to the body. Because the plys are glued in a book matched style the neck will not  twist or warp.

Various colored woods can be used to beautifully match the body woods.  

One of the more obvious features is the pinless bridge. This bridge weighs 45% less than the traditional type. Reducing weight on the soundboard increases vibrations which in turn increases volume, projection and sustain. Changing strings is a simple task without pins that often tend to jam or break. The 30 degrees break angle over the saddle  will transmit vibrations to the soundboard much more effectively than the typical angle of 15 degrees or often less.     

All soundboards are built with a 30 foot radius. It is cylindrical and built into the top with the braces. It adds strength and stiffness to the the top that also increases volume and projection.
