Yamaha YBL822G Professional Bass Trombone

This model is a refined version of the very successful YBL622 and like its predecessor was developed with a the great artist Douglas Yeo of the Boston Symphony at the time. There have been many small technical improvements, but the results are far from small. The sound from the gold-brass bell is even warmer, the valve register more responsive, and the overall playability more flexible.
