Schilke 59 Silver Plated SP, Large Shank Standard Series Bass Trombone Mouthpiece ★Cup Diameter: 28.52mm ★Cup Depth: Deep *Not a long shank ★Purchased new, used for a few test plays. There are slight insertion marks on the shank, but it has been used very little and the appearance is like new. This is a standard model favored by many bass trombone players, characterized by its thick and powerful sound. With a cup diameter slightly smaller than the largest Schilke 60, it offers high controllability and is easy to handle. Schilke mouthpieces have subtle differences in shape depending on the manufacturing period, but this one is a relatively recent specification.
