Yamaha YSL640 Professional Trombone

Newly redesigned 600 Series trombones provide competitive pricing with top of the line features. Their broad sound has a well-defined tonal core for excellent projection in all registers.

Features

• Bell taper: The YSL-640 has a continuous taper bell section that improves intonation with even resistance in all registers.
• Inner slide: The chrome-plated, nickel silver, drawn, inner slide is very durable and has a quick, sensitive response.
• Outer slide: The one-piece, drawn, yellow brass outer slide maintains an accurate diameter throughout its length, and this type of construction ensures airtightness, smooth action, exceptional durability, and adds resonance to the sound.
• Inner slide stockings: Specially designed one-piece inner slide stockings guarantee airtight slide construction, and offer smoother slide action and better alignment, even in the extended 6th and 7th positions.
• Tubular braces: Long-lasting nickel-silver tubular braces contribute to the stability of the slide and enhance smooth slide action.
• Hand-lapped tuning slides: Hand-lapping slides ensures an absolutely perfect fit and seal between the slide parts. Such a perfect fit helps to achieve smooth air flow and smooth action and improve the response and intonation of the instrument.
• Pressure-formed tubing: Perfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance.
• Laser-fused pluzuma welded bell: A high-energy laser fuses the brass together for a virtually seamless bell which allows continuous, even vibrations.
• Slide lock: The unique slide lock design on all Yamaha trombones keeps the slide locked in place and keeps it from accidentally falling.
• Bracing: The large, easy-to-hold, nickel-silver bracing guards against possible slide damage if the instrument is dropped and also lessens fatigue while playing.
• Mouthpipe: Yamaha trombones have mouthpipes featuring special acoustic designs allowing for precise intonation and greater blowing control.
• Rotor: Large rotor on "F" attachment, with a mechanical linkage, allows for smooth transitions from the Bb to F side with less resistance.
• Hand-lapped rotary valve: The hand-lapped rotary valve provides airtight, light action, allowing quick and smooth valve switching
