The Tama by Kanstul T3C has a larger cup diameter and depth to the standard 3C, with the #24 orchestral back bore. This gives the mouthpiece a very dark yet powerful tone quality, which is needed for use on the field. The size and power of this mouthpiece matches very well with the power that is needed by our Coliseum Trumpet. Once a trade secret of professional trumpet players in the greater Los Angeles area, the word about the T3C has spread to many commercial and orchestral circles.
