The basis for the manufacture of new drums is the constant analysis and review of existing instruments. The mastery of basics is the fundament of new drum developments. Therefore regulary frequency analyses and comparison tests are an important part of my drum production, as well as self-made tools and special devices.

Here you can see a few photos of our great studio comparison test where all of my drums have been analyzed and tested. Exact frequency analyses have been made of all of them. Jürgen Treyz in his sound recording studio (artes records), Rolf Wagels in the recording room.
