Innovation out of tradition

As a passionate instrument craftsman, I take the responsibility associated with the use of tonewoods and the sometimes decade-long “maturation” very seriously. Sustainability is a key focus for me, especially in the craft of instrument making. That is why I support and use modern and trendsetting techniques in woodworking.

Thermo modification

300 years in 3 days

»HAGEN WEISE« processes spruce and maple for the top and back on request, which have reached their maturity in a technical process developed by our showroom partner Armin Hanika in cooperation with the Technical University of Dresden.
In the so-called thermo-modification process, already seasoned tone woods are subjected to a maturing process in just a few days, which emulates a storage period of up to several centuries. This technology excitingly makes it possible to create near-original results when building copies of old masters, even in the area of sound characteristics. In addition, thermal modification in the field of wood selection, wood storage and maturation opens up completely new ways of thinking when it comes to violin-making.

Regional alternatives to tropical timber

Because of the overexploitation of tropical timber, violin making needs a sustainable alternative. Sonowood, made of compacted Swiss wood has a high speed of sound conduction and is particularly hard and strong. From it Wilhelm Geigenbau makes fingerboards & tailpieces with its CNC machines and by hand,
pegs, chin rests and endpins. The wood structure is largely preserved and gives the accessories vivid beauty. The wood, selected according to acoustic criteria, improves the instrument’s response and enables a greater sound projection. The fine design of the accessories takes full advantage of the unique properties of the material. The models have been tonally optimized in close cooperation with musicians and fellow luthiers.
