The TT4L S1 is the “Large Throat” version of the TT4 S1.  Our Large Throat trombone mouthpieces are great for players who have a very open and aligned approach to playing, and always take a great breath.  The sound shape is wider and broader than the standard throat version of the TT4 S1.


  • 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.
