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


The FLG MF III has the same rim as our very popular MF III lead mouthpiece. The MF III was designed for Maynard Ferguson and is one of our most popular lead trumpet mouthpieces. This rim is considered comparable in size to the Schilke size 13. The FLG MF III is a great option if you are looking for a rim similar in size to mouthpieces like the 'Bobby Shew Lead' or 'Wayne Bergeron Studio.' The rim has less bite than the similar-sized MF II and BL2.
