This box we play, made of wood from various places in my own case: cedar top from British Columbia. rosewood back and sides from Brazil, ebony fingerboard from Africa and mahogany neck from Mexico. This range is remarkable, the result of international trade but the masterful skill a luthier uses to finish a guitar is extraordinary. From the design perspective there is the analysis of all the precedents both for the practical purpose of making sure it stays together, and the aesthetic reason of making a beautiful sound that responds to the players skill and needs.
