The YSL-897Z was developed with Andy Martin.

The YSL-897Z comes with 2 interchangeable leadpipes, Z1 and Z2.

The new balancer found on the YSL-897Z perfectly proportions the instrument’s weight.

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.

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.

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-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.

Perfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance.

A hand-hammered bell maximizes tone and projection.

The large, easy-to-hold nickel silver bracing guards against possible slide damage if the instrument is dropped and also lessens fatigue while playing.
