【YAMAHA Custom Xeno YSL-882VG Tenor Bass Trombone】 A tenor bass trombone that fills concert halls with emotion, featuring an innovative new valve system. The heavy bell, made with Xeno-exclusive materials, is a one-piece, hand-hammered bell. Yamaha's unique V valve and dedicated F-attachment layout significantly reduce resistance changes when using the F-attachment. The bore size and shape within the valve have also been carefully considered, providing a moderate level of resistance across the entire range. This is a high-end model that fully meets the high-level demands and exacting musicality of professionals. Xeno series B♭/F. The bell is gold brass, one-piece, 216mm in diameter; the outer slide tubes are yellow brass, the inner slide tubes are nickel silver; the bore size is large bore 13.89mm, and it has a clear lacquer finish. This is one of the few G-bell specification models equipped with the V valve, which is now discontinued. There are some lacquer imperfections and scratches due to age and use, but each moving part is smooth and in good condition, with no problems in use. Comes with the original case.
