Model BT-2 A great size for big band and commercial work, this model has a rich, full sound with great flexibility! Developed for our friend Ken Shirk of Portland, Oregon.

Model BT-1S With the same rim as our BT-1 and BT-1L, this model has a slightly shallower cup, which helps provide a slightly brighter sound and greater ease in the upper register.

Model BT-1 A true orchestral bass trombone mouthpiece, this model has a very comfortable, large rim, an extra large cup, and a monstrous sound! The upper register is surprisingly easy when the player stays open and relaxed! Also available as the BT-1L, with an extra large throat. This first model of Monette orchestral bass trombone mouthpiece was developed for John Englekist, principal bass trombone of the San Francisco Symphony.
