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


The FLG 4 is made with our B4 rim, the same rim as our B4 S3 trumpet mouthpiece (and the old non-Slap B4). This is not to be confused with the B4S rim (B4S S2, FLG 4S, etc.) The B4 rim is considered comparable in size to the rims of the Bach 1-1/2C or Schilke 16. This rim is slightly thick and flat, with a bit of bite to the inside edge. If you prefer a more rounded rim contour, we recommend the FLG 4S.

  • 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.
