willie's Custom Brass Willie's Trombone Mouthpiece HIRO NEO Series HIRO NEO Large Bore Tenor 645 (GP)

A variation model by Hiroo Yamashita of the Takarazuka Revue Orchestra. Although the cup itself is shallow, it is hollowed out larger than the inner diameter of the rim, making it an extremely unique mouthpiece that combines the high range of a thin-bore tenor and the low range of a bass trombone. Supervisor: Hiroo Yamashita (Takarazuka Revue Orchestra) Rim diameter: 26.45 (mm) Throat diameter: 7.9 (mm)
