Bach 3416HAL 6-1/2AL Trombone Mouthpiece (Large Shank)
- Medium deep cup depth
- 25.40 mm cup diameter
- Medium wide, well-rounded rim
- The same rim and cup as No . 6 1/2 A, but with a larger "G" throat and #420 backbore for tromonists who strive for a Teutonic tone quality. Recommended for euphonium players who desire a round, mellow tone of great carrying power and substantial volume.
