Designed with world-renowned trombonist Andy Martin, the YSL-897Z Custom Z trombone is perfectly suited for a wide variety of performance situations and features two interchangeable leadpipes named Z1 and Z2. Inner Slide The chrome-plated nickel-silver drawn inner slide is very durable and has a quick, sensitive response. In addition, it is a one-piece drawn slide. Outer Slide The one-piece, drawn, brass outer slide maintains an accurate diameter throughout its length, and this type of construction ensures airtightness, smooth action, and exceptional durability. The outer slide is fit with extremely close tolerances making the trombone respond quickly and effortlessly. 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.Mindre
