Immediate purchase OK Alto saxophone mouthpiece "Claude Delangle" Claude Delangle I used a JLV ligature, so there are scratches on the surface. Comes with a pouch and presentation box. ---------- The metal ring and cut design, which are said to be characteristic of Adolphe Sax's first mouthpiece, are based on the tradition cultivated so far and the know-how gained from the development of the Concept series, and have been completed as an "ebonite and metal hybrid" mouthpiece. A gold-plated metal ring covers the entire bore, enhancing sound projection and providing a more precise and rich sound.
