For over 42 years, Wolfgang worked with musicians from more than 90 countries. Experiencing the musician's needs from so many different cultures and environments has built an understanding of the necessity of individual solutions. In tight collaboration with many of the world's top musicians, excellent solutions and techniques have been developed to solve numerous problems. Among them are noise reduction systems, new padding methods and systems, ergonomic improvements, and the elimination of climate and humidity influence, crack prevention, water reductions, and many acoustical improvements.
Wolfgang is a requested lecturer and has led workshops and seminars at international festivals and conferences in Europe, USA, Canada, Latin, and South America, Israel, Asia, Tanzania, and Russia.
