About Yamaha Professional Trombones

Yamaha Professional and Custom Trombones feature chrome-plated nickel-silver inner slides for durability and response. The one-piece drawn construction of inner and outer slides ensures better alignment and lighter overall slide weight. The Custom Series is crafted using the latest in technological innovation. The 600 Series features a two-piece bell for maximum tone, projection and dark tonal color. F-attachment trombones feature large, hand-lapped rotary valves for a free-blowing and quick response.

Features

• Inner slide: The chrome-plated nickel-silver, drawn, inner slide is very durable and has a quick, sensitive response.
• Outer slide: The drawn, yellow brass outer slide maintains an accurate diameter throughout its length, and this type of construction ensures airtightness, smooth action, exceptional durability, and offers improved response.
• 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-hammered one-piece bell: A one-piece bell has an axial (lengthwise) seam, making it a continuous extension of the instrument's material. This results in pure, uniform resonance and superior tone. A hammered yellow brass bell produces a perfectly-balanced tone with quick response and extra presence due to advanced manufacturing techniques.
• Hand-lapped tuning slide: 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.
