My guitars are designed with the outline of a Herman Hauser guitar with a slightly more rounded bottom. My Bracing patterns are a copy of Daniel Friederich. Daniel Friederich guitars are played by some of the best players in the world, his guitars are highly coveted and very valuable. I find his bracing pattern produces a quality of sound that gives a better separation between brightly singing trebles and a depth of base. I find the sustain and overtones to be much better as well, and who can dispute his success he is considered to be the best living builder of this era.
