Yamaha Trombone 690 Series Professional

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, nickel-silver outer slide maintains an accurate diameter throughout its length, and this type of construction ensures airtightness, smooth action, and exceptional durability. The YSL-691 has an ultra-lightweight slide so it can have lighter action without losing the center of 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 ontribute 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 pure and perfectly-balanced tone with quick response and extra presence due to advanced manufacturing techniques. 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. Balancer The balancer found on the YSL-691 perfectly proportions the instrument's weight. 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. Tone Full-bodied throughout the register is the characteristic tone of the YSL-691. Mouthpipes Three different mouthpipes are included with the YSL-691, and each one emphasizes the focus, edge, and warmth corresponding to the player's individual style.
