For sale is a brand-new, completely unplayed Yamaha YSL-640 Professional Tenor Trombone with F-attachment.

The trombone has never been played or had a breath blown through it. It was removed from the packaging only to verify the contents and take photographs. It remains in pristine factory condition with no dents, scratches, lacquer wear, or signs of use.

The YSL-640 is a versatile professional-grade Bb/F tenor trombone with a medium-large .525-inch bore. Its two-piece 8½-inch yellow-brass bell provides a warm, focused sound, strong projection, and responsive articulation. It is an excellent choice for advanced students, serious amateurs, and working musicians seeking a versatile horn suitable for concert band, orchestra, jazz, pit work, and general performance.
