Schilke trumpet mouthpiece MOST 1, silver-plated. This mouthpiece was developed in collaboration with world-class top players, including Atsushi Takahashi, principal trumpet player of the Tokyo Metropolitan Symphony Orchestra, and Toshio Tanaka, trumpet player of the Yomiuri Nippon Symphony Orchestra, and the Schilke company. MOST 1 is Takahashi's model. The specifications are: rim size of Mount Vernon Bach 1C, throat 22, and backbore 7. Although it has a large rim and throat, it offers a very smooth playing feel, a wonderful tone, excellent intonation, and a well-balanced sound.
