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


The FLG 12 ('one two') is made with our B1-2 rim. Trumpet mouthpieces with this rim are: 

  • B1-2 S3
  • B1-2LD S1
  • old non-Slap B1-2


The B1-2 rim is large in diameter, similar to the rims of the Bach 1X, Schilke 18 and 20, and other similar sizes. This rim is also on the flat side.

  • 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.
