Contrabass Trombone in Bb with Double Slide

Model Description

The THEIN Contrabass Trombone in Bb/F with double slide enables the player to use the same slide positions as with a bass trombone. The lower range is a bit difficult to play takes getting used to.

For a bass trombonist, it is easier to change to a F-Contrabass trombone then to the Bb/F with double slide.

THEIN recommends a mouthpiece with a smaller cup-diameter (size of a bass trombone mouthpiece).
