The extent to which the manufacturing possibilitiesinfluence the design of Teuffel’s guitar models is illustrated by the layout and structure of the birdfish. Its design embodies the idea of industrial manufacturing: modularity, separation, flexibility, and variety in materials. On the birdfish, a musician can change or move the pickups, tonewoods, and other functional elements. This would be impossible without the dimensional accuracy provided by a precise CNC machine. Customers get several part sets for their instruments, with each configuration having its own character in terms of sound.
Teuffel’s newer guitar designs — such as the niva, tesla, and antonio — also show how much of a perfectionist he is. Where other guitar makers’ fret slots are sawed into the neck of the guitar, he uses end mills in his Reichenbacher milling machine with the SINUMERIK 840D sl. The reason is clear, as Teuffel explains: "This means that the edge of the fret slot is kept and the neck of the guitar is intact and smooth at the side — which makes the guitar considerably nicer to play." However, getting there took a long time, remembers the guitar maker: "Wood is a special material, and every type has its own characteristics. Even rounding edges requires very differentiated machining strategies and precise control, otherwise the wood can start to splinter. In the beginning I had the milling done by other model makers, but the results always fell short of my expectations. Today, other than a few screws, electronic elements, and the strings, I make everything myself — including the lacquer and parts of the pickups."
