Demo Yamaha YSL-881 Professional Bb Tenor Trombone. .547" bore hand slide, 8.5" bell flare. Instrument is in demo condition with no visible signs of wear. Comes with original case.
Great sounding, clear articulating bell. Can handle high volume in the high range and still not break. Great slide. Would liked it to have removable leadpipe. Could see this as orchestra horn w/f attachment but without could make a great jazz horn for strong player.
