Bach Standard Bass Trombone 1½G Mouthpiece| Large Shank

The Bach 1½G large shank mouthpiece is one of the most iconic and widely used bass trombone mouthpieces in the world. Featuring a very deep cup and large inner diameter, the 1½G is designed to produce a huge, broad sound with exceptional depth, projection and low-register power. Its symphonic design supports a rich tonal core with the warmth and authority needed for modern bass trombone performance in large ensembles.

Bass trombonists appreciate the Bach 1½G for its commanding low-register response and full orchestral sound. The larger cup and throat design allow players to move a significant amount of air while still maintaining clarity and flexibility throughout the range of the instrument. Whether performing in wind ensemble, symphonic band, orchestra or brass ensemble settings, the 1½G remains a longtime standard for bass trombone players seeking a powerful, mature and resonant sound.
