Ideal for the developing musician. Featuring a beautiful rich tone and easy playability the YSL-447GE large bore is designed for players who are progressing past the grade 5 standard. Similar to Yamahas professional range of trombones the YSL-447GE features an 8-1/2 bell and a 0.547 bore. This combination of a large bell and large perfectly suits the YSL-447GE for symphonic orchestras and brass bands. Included with the trombone is a moulded hard case and a large shank Yamaha 48 mouthpiece so you can start practising straight away.
