Smooth playing and beautifully toned.

This Yamaha YSL-640 Professional Trombone is a smooth playing, responsive instrument for the experienced trombone player. Features like hand-lapped tuning slides and hand-lapped rotary valves ensure a perfect, airtight fit. The string linkage of the valves allows for easy adjustments and a unique slide lock keeps the slide in place and prevents it from falling. The inner slide is chrome-plated nickel silver making it both durable and reliable. The drawn yellow brass one-piece outer slide has a consistent diameter throughout its length adding resonance to the instrument while remaining airtight. Tubular braces composed of durable nickel silver stabilize the slide while promoting smooth action. The laser-fused bell is virtually seamless resulting in even vibrations. A continuous taper bell section produces even resonance throughout all registers. The mouthpiece features a special acoustic design that allows greater blowing control and precise intonation. A large rotor on the œF attachment makes transitions from Bb to F exceptionally smooth. For a skilled, responsive instrument the Yamaha YSL-640 Professional Trombone is an exceptional value. All Yamaha woodwinds come with a limited 5-year warranty.

You deserve a professional level horn. This is a great one. Order today.

Comments about Yamaha YSL-640 Professional Trombone:

I played this instrument a week ago at the Music Messe, Frankfurth Germany. This trombone is like a Rolls Royce. Is beautifull. Plays like a feather. Nice tone, nice resistance, F attachment incredible. Good for every style jazz, clasical, salsa, etc.
