This is a VERY NICE Yamaha YCB-621S 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 enough 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. Original silver plate is 95% present with very minor wear. There are a couple of minor dents but nothing serious. Valves are very good and this tuba plays well as is. GREAT TUBA! Don't miss tihs one! Please feel free to email with additional questions. Bid early, bid often!!!
