YBL-421GE Bass Trombone

A semi-open wrap gives this intermediate level bass trombone a smoother airflow and open sound. Yamaha's Intermediate model bass trombone features many of the qualities of our top pro models, yet is available at a surprisingly affordable price. It has the same bell and bore size as most pro models, and the bell is gold-brass for a sound both rich and full.
