Bass Trombone

So that it rattles like a Harley – the HAAG bass trombones for every taste

HAAG was the first to install the Thayer and Bosc valves as standard in the tenor trombones. Thanks to innovative work, the Thayer valve was completely redeveloped in 2018 and promises an even better response across all registers. 

HAAG has been installing Thayer valves in trombones for thirty years. The ThurBone is also equipped with the latest axial valve on the market. This enables a completely new and free playing experience. Since the ThurBones are handcrafted, master instrument maker Fabian Bächi enables you to build your instrument, which is specially made to your needs.
