The Karif features a deep bowl shape cup and large rim diameter, similar to the Chinook and Don Harwood mouthpieces. However, the Karif projects a powerful, pure tone. The Karif differentiates itself with a quick response, accurate articulation, and pays special attention to the beautiful upper overtones the bass trombone produces. The Karif is ideal for those looking for a versatile bass trombone mouthpiece at home in all playing situations and ensembles.
