Yamaha Bass Trombone Xeno Professional Model YBL-620G

The YBL-620G features a dark rich tone with powerful projection. The outer slide is nickel-silver for durability and the valves are in an offset configuration. This model is lighter than the others, making it easier to hold and giving it a very quick response. Designed with the budget-conscious band director in mind, this new professional bass trombone has a smaller bell size that offers excellent tone for the advancing bass trombonist.
