Ideal for the developing musician. Featuring a beautiful rich tone and easy playability the YSL-446GE Bb/F large bore is designed for players who are progressing past the grade 5 standard. Similar to Yamahas professional range of trombones the YSL-446GE features an 8-1/2 bell and a 0.525 bore. This combination of large bell and medium bore enables the Yamaha trombone to be played in virtually any musical situation. Included with the trombone is a moulded hard case and a small shank Yamaha 48 mouthpiece so you can start practising straight away.
