Smooth playing and beautifully toned.

The YSL-640 has a continuous taper bell section that improves intonation with even resistance in all registers. The chrome-plated, nickel silver, drawn inner slide is very durable and has a quick, sensitive response. The outer slide is one piece, drawn yellow brass and maintains an accurate diameter throughout its length. This type of construction ensures airtightness, smooth action, exceptional durability, and adds resonance to the sound. Long-lasting nickel-silver tubular braces contribute to the stability of the slide and enhance smooth slide action. Tuning slides are hand lapped to ensure an absolutely perfect fit and seal between the slide parts.

The virtually seamless bell--fused by high-energy laser--allows continuous, even vibration. The unique slide lock design on all Yamaha trombones keeps the slide locked in place and prevents it from accidentally falling. Large, easy-to-hold, nickel-silver bracing guards against possible slide damage if the instrument is dropped and also lessens fatigue while playing. Mouthpipe features a special acoustic design that allows precise intonation and greater blowing control. Large rotor on "F" attachment makes transitions from the Bb to F smoother. The hand-lapped rotary valves provide airtight, light action for quick and smooth valve switching, while the string linkage permits flexible adjustment.
All Yamaha wind instruments 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'm an old hand who finally came around to the modern world. I've played vintage horns for years. I finally broke down and after much thought and ado settled on this horn. Why? Because I figured it was versatile to all my types of playing from jazz to symphonic etc. AND, it is in spades. It has a wonderful sound and is very responsive in all registers. It blows easy. I would not use this horn as a lead horn in a jazz ensemble, it is too mellow for that use. If you want to make 'em weep, this is it. As you can tell, I love this horn.

Comments about Yamaha YSL-640 Professional Trombone:

To begin, I shopped for a new Tbone for over a year. I play various styles and wanted something versatile, something that would respond to my playing. I must say, the Yamaha YSL-640 has lived up to the Yamaha hype. From intonation to its weight, I have been extremely pleased. Even more impressive was the service of WWBW. The website said 4-6 weeks back order which was confirmed when I called and placed my order. To my surprise, I found my new horn in my garage when I cam home for lunch.....8 DAYS LATER!!! Excellent Trombone/Excellent Experience!!!
