The TT4 S1 is similar to our TT5 S1 mouthpiece, but in a slightly larger rim diameter.  Our TT4 S1 compares to the 4G size, and is popular with orchestral and symphonic players.  It is a great mouthpiece for anyone looking for faster response and cleaner articulation while still playing a larger orchestral mouthpiece.  The TT4 S1 is also available with a larger throat size (TT4L 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.
