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


The FLG 4S has the same rim as our B4S S2 (and the old non-Slap B4S), which is our most popular equivalent size to the Bach 1-1/2C, Schilke 16, and other similar sizes. If you use a trumpet mouthpiece in this size range, including the Silver Monette 4 and Tradition PLUS 3, this is an excellent choice.

For help deciding between Classic and Prana, please see our Mouthpiece Selection Guide (in the Mouthpieces menu at the top of the page).

Resonance 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.
