Model Description

The THEIN Bass Trombone “Universal” Dependent model has been continuously developed together with Zachary Bond (Hong Kong Academy for Performing Arts) since 2010. Our idea was to combine the THEIN-Sound with the easy playability of the American trombone construction.

The dependent valves give the musician while playing the easy feeling of a tenor trombone with a quart valve. Therefore the THEIN Bass Trombone “Universal” Dependent model is often played by Wechselposaunisten.

Zack Bond:  „I have never played another instrument that was so dynamic, responsive and colorful“.
