Innovative guitar making
"Der Gitarrenentwurf nach Prof. Dr. Michael Kasha. Beschreibung und Analyse", Diplomarbeit 2004 [PDF ca. 6 MB] (German)
Diploma Thesis about the research work of the American biophysicist professor Michael Kasha PhD in the field of guitar making. Since the middle of the 1970s of the 20th century Kasha deals with the construction of concert and steel string guitars. His objective is to improve them in their acoustic function. In cooperation with the luthier Richard Schneider and others, Kasha developed a new concept for the construction of concert and steel string guitars in over 30 years. This way of construction differs from traditional ways of construction regarding the approach and realization and is discussed controversially.

"Das Modell „Rekord" von Richard Jacob „Weißgerber". Beschreibung und Analyse", Projektarbeit 2003 [PDF ca. 2,7 MB] (German)
Project thesis about the guitar model “Rekord” made by the luthier Richard Jakob “Weißgerber” (1877-1960) including the measurement, description, and photo documentation of two preserved Rekord-models und the analysis of the available source material. The design strikes with its unique corpus shape and was formed in Weißgerber’s early creative phase. Especially the peculiarity and the design of the model Rekord are analyzed as well as the sound properties and meaning for guitar making. It was investigated, whether the golden section was used as a basis for proportions for the model Rekord and which other rules of proportion were applied.
