Contrabass Trombone

The flagship of the HAAG Brass

The Contrabass trombones were the first HAAG instruments to gain a foothold outside of Europe. They can now be heard in the biggest Hollywood blockbusters as well as in various operas – from North America to Australia.

The HAAG trombones have been pioneers in installing the Thayer valve for over three decades. The ThurBone is equipped with the latest axial valve on the market and offers a completely new, free feel! The HAAG ThurBones can be built individually to your needs.
