The A1 Traditional Custom Series is an instrument that is well-suited for concert band or orchestral playing when the sound needs additional projection. The A1 features a medium-large .460-inch bore design coupled with a #1 taper large throat yellow brass bell. This combination, along with the long-model body design and Shepherds Crook help to provide a more focused sound with maximum projection. The A1 cornet is available in lacquer or silver plate finish.
