Model Description

The THEIN Bass Trombone “Universal” model has been continuously developed together with Zachary Bond (Hong Kong Academy for Performing Arts) since 2010. Their idea was to combine the THEIN-Sound with the easy playability of the American trombone construction. This example has minor scratches on the bell, from Thein at a show, otherwise brand-new!

Zack Bond:  "I have never played another instrument that was so dynamic, responsive and colorful."
