This ia an excellent Yamaha YSL-695 Trombone, ideal for professional use for jazz/big band. It is .500 bore with 7.5in bell and is the trombone that preceded the 697z, and plays superbly with an excellent slide. It comes with an almost new gold finished Denis Wick 9BS mouthpiece which suits the instrument well. I am selling it as I no longer have use for it as I prefer a larger bore (and have 6 other trombones of various types!). The instrument has only had light use, with very few marks. The inner slide has no wear showing and the instrument looks almost new. The instrument comes with the M2 lead pipe which is what most people use. The case is in very good solid condition but does have a couple of scuff marks. Overall a quality trombone for a fraction of the price of a new one. This is the trombone that Don Lusher played on. It plays beautifully with a lovely clear tone and lovely slotted harmonics. This practically as new as it can get, a real bargain.
