Yamaha Professional Jazz Trombone, model 651 that was made from 1969-1975. This is a .500 bore with a 8' bell, in excellent original condition.This is a very light and comfortable horn with a might and easy upper register playing, it is a great all around horn suitable for jazz, funk, latin and pop-rock music.The instrument was professionally cleaned prior to this sale.It is in perfect condition both light weight slide and red brass bell. There's a minor thing about this instrument, the tuning slide has one tinny dent in the that can be seen in the picture, but does not affect the sound.It comes with the original case and mouthpiece, as well the cleaning kit.Any question fell free to ask.
