Model description

The THEIN Tenor Trombone in Bb/F “Old German Style” was developed with and for Jay Friedman (Chicago Symphony Orchestra) as part of the project “Old German Style – Alto, Tenor, Bass Trombone”. A historical “Kruspe” tenor trombone in yellow brass without tuning slide and without valve served as a template.

THEIN redesigned this model with tuning bow and F-Attachment.

This instrument is our “most German” THEIN tenor trombone in terms of sound and playability. The German slide positions take getting used to.

The sound is rich in overtones and vocal, with an earthy touch.
