*All new flugelhorn mouthpieces are now made in the Resonance body shape.


The FLG L has the same rim as our BL S1 lead mouthpiece. Other mouthpieces with this rim are: 

  • BLM S1
  • BLD S1
  • old non-Slap BL
  • old non-Slap B6L


The BL rim size is considered comparable in size to the Schilke 14, and similar to a Bach size 7. If you are most comfortable with a rim size like that, or use one of our trumpet mouthpieces with the BL rim, the FLG L is an excellent choice.

  • Monette mouthpieces are made to order and take about 6-8 weeks 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.
