One of the top notch professional alto trombones, the Yamaha YSL-871 Custom.
It features a .470/490 dual bore nickel silver slide with a yellow brass crook and a yellow brass bell section. This instrument is in excellent condition. One tiny ding on the bell flare, lacquer is 99.9% intact. This might be your entry horn into the world of alto trombones, but it could also be the only alto you’ll ever need.
