By utilizing a bowl shaped back for the sound-box of the instrument but retaining the traditional flat top of Sitka spruce for the soundboard, they hit upon a combination that produced an instrument that was louder, lighter in weight and stronger than traditional wood guitars. Understanding the inherent strengths of the parabolic arch in physics, the Kaman designers began experimenting with this shape while working with composite materials. The first prototypes using synthetics proved disappointing when constructing guitars in the traditional manner with flat backs and bent sides. In 1964 he instructed a team of engineers at Kaman Aircraft to see what new designs could be achieved. As an amateur guitarist, he began investigating which modern synthetic materials could be used in guitar construction.
