The BT 1S V4 has the same rim as our BT 1 and BT 1L, but with a slightly shallower cup.  It is great for players who like the large BT 1 rim size, but would like a slightly brighter sound and easier upper register.


  • Monette trombone and tuba mouthpieces are made to order and take about 3-6 months to produce. The mouthpiece will ship immediately when available - even if this is ahead of the production schedule. In the event of an unexpected production delay, Monette staff will contact you directly to update you regarding delivery schedule.

  • Due to the unique nature of our made to order products, we do not provide return, refund, or exchange services.
