Trombone

Trombones can be built very differently even in the same tuning.
For example, in Bb there are both tenor trombones in various designs and bass trombones, again in a wide variety of versions.

My idea was to develop a type of tenor trombone in Eb that would better meet the needs and wishes of a jazz trombonist than the generally common narrow-bore jazz trombones in Bb. With the help of the brilliant trombone maker Josef Gopp, I managed to do this.

The result is the Casimir-Alto, which has been my absolute favorite trombone ever since!

The development of the trombone was supported by the "Mécénat Groupe BALAS" foundation fund. Therefore I would like to express my gratitude once again!

I also occasionally play my large-bore Bb tenor trombone by Pierre Hulot, which I helped develop, and a medium-bore Bb tenor trombone by Olds, the Recording R20. The latter was considered a bass trombone when it was built!
How times change!
