This is the guitar that I have been making and improving since I began. It has undergone a lot of changes in general shape and internal structure. I think these changes are for the better and that I am making the best guitar I can today. I started out with a shape borrowed from Hauser and although I used his bracing it was a very different concept. I arch the top and make it thinner than he did. The plan I used was of a very shallow instrument and it was relatively successful. Over the years I experimented with a deeper body, new shapes and a different internal structure and although I continue to search for improvements I have found a great combination of all these elements. My concert guitar has a bit smaller outline but is deeper and has 5 fan braces instead of 7. So, unless someone specifically asks me to go back to what I was doing before I will stick to this.
