This is a Dillon mouthpiece, the Claudio Roditi model, for rotary trumpet, used by a master who brilliantly performs JAZZ. This is a Dillon Claudio Roditi model mouthpiece. This mouthpiece is said to have been used by Roy Hargrove. Mr. Roditi has long used a GANTER B♭ trumpet, and in recent years has been playing a SCHAGERL B♭ rotary trumpet. The size feels slightly larger than a Bach 3C, and the cup seems slightly deeper than a 3C. The rim has an anchor grip, providing a very comfortable fit in the mouth and a sense of stability. Also, the mouthpiece is light, so the response is very good, and you can tell that the intonation changes dramatically. Of course, it can also be used in classical wind bands and orchestras. It's a vintage item from about 20 years ago, and it's a hard-to-find mouthpiece that is rarely seen now.
