Model Description

The THEIN Rotary Bass Trombone “Classic” combines the German sound with the easy playability of the American trombone. The “standard rotor” valves give the player a little more resistance and thus increase the control of a safe tone.

The beauty of this German sound, rich in overtones, is unimaginable and inspires every musician. As an option, we recommend our special metal alloy, THEIN K-Style metal. It enhances the proportion of overtones and the earthiness in the base of the sound.
