Yamaha YSL-640 Professional Trombone (YSL640 YSL 640)

Yamaha YSL-640 Professional Trombone (YSL640 YSL 640)

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.
