This is a PERFECT Yamaha YCB-621 Tuba in CC. These are some of the best CC tubas currently available. 4 short action pistons and 3/4 size make a nice compact sound that is perfect for chamber brass or smaller ensembles, but versatile enoguh to play in any orchestra up to about Russian symphonies :). Yamaha's unerring attention to detail and superb craftsmanship should surprise no one, and these horns are played by professional symphony players all over the world. This horn is in perfect condition. It was a short term rental and literally has less than an hour of playing time on it. GREAT TUBA! Don't miss tihs one! Please feel free to email with additional questions. Bid early, bid often!!!
