This is a MINT Yamaha YSL-891Z custom trombone. This model was developed with Andy Martin and Wycliffe Gordon, and is an incredible instrument. These are GREAT playing horns. Like all Yamahas they speak very clearly, and have an open, direct sound. The 2 leadpipes allow you to customize the horn to suit your own playing characteristics. They have a .508 bore for a full sound but great flexibility and response. This particular one is in perfect condition It has had no more than an hour or two of playing time and has no flaws except for fingerprints. This horn is exactly the horn you want for rock 'n roll, big band, or salsa. Pics tell the rest of the story! Please feel free to email with additional questions. Bid early, bid often!!!
