This is a Giardinelli mouthpiece, favored by countless famous players such as Miles Davis, Maynard Ferguson, and Chuck Mangione. It was made by the same craftsman who made the ones they favored (strictly speaking, several staff members like Greg Black were employed), and it is from the "old stamp" period, known for its meticulous craftsmanship. The stamp reads "GIARDINELLI NEW YORK 17S". It has a smaller diameter than a Bach 12 and a shallow cup. It can be used for jazz performance on an American cornet or as a mouthpiece for a piccolo trumpet. It is unplated and made of solid brass. It is a 2-piece model with a screw rim. In recent years, small-sized Giardinelli mouthpieces with the old stamp have rarely appeared on the market. I am offering it at a low price, so I believe this is a great opportunity! Please feel free to contact me with any questions or price negotiations. Thank you very much.
