The Thein Bass Trombone “BvD” has been continuously developed together with Ben van Dijk since the late 1980s until today.

The beautiful, full, warm bass trombone sound is unique in its rich overtones, resulting in part from the compact design of the valve. The exposed bows make it easy to play in all registers. With an added Thein hand support, an exceptionally easy playing is achieved.
