Excellent experience...

‘’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. Excellent Trombone/Excellent Experience.’’

YamahaYSL 640 a big hit!

‘’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.’’
