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


The FLG 4LD has the same rim as the semi-shallow B4LD S1 trumpet mouthpiece. (The standard-depth B4LD/2 S3 and the old non-Slap B4LD have this same rim as well.) The FLG 4LD is made for players who use the B4LD S1 (or B4LD/2 S3) and want the exact same rim when playing flugelhorn.

  • 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.
