Bass clarinet

German Fingering (Model 2000) and French Fingering (Model 3000)

The way our bass clarinet is designed, it can be constructed with German fingering, as well as French fingering, depending on preference. Their tonal performance is equally strong. Elements of either type can be combined according to individual customer wishes.

Based on the German bore, we have developed an innovative concept for this world-class bass clarinet. Due to its new scale and its specially developed shape, the newly designed neck has a major influence on the instrument’s sound and intonation. The novel vent hole mechanism no longer requires a valve in the neck. It impresses by having an interference-free automatism with a whisper key mechanism. A metallic elbow is added to the lower joint to fit an upward-facing wooden bell. The innovatively designed and well-proportioned mechanic parts result in a compact key positioning – perfect for all hand sizes. Controlling the thumb keys via newly developed levers, designed to have the shortest possible lifting point, makes for a quicker and more precise playing of the four lowest notes.
