The BC Master flugel mouthpiece has an inside rim diameter of .625″. The rim is round on the outside edge and medium round on the inside. It has a deep flugel cup and the Legends flugel backbore. The heavyweight blank adds core and darkens the tone, creating that sought-after fluffy flugel sound. An added bonus with this model is that it has a matching trumpet mouthpiece, the BC Master. The rims are identical, allowing the player to quickly and easily transition between flugel and trumpet. The two together make a nice trumpet/flugel kit, perfect for those gigs where you want to play some intense jazz-rock and some laid back flugel jazz, too.

If you like the BC Master Flugel consider the BC Master mouthpiece for your trumpet. These two mouthpieces have identical rims, which makes for seamless transition between trumpet and flugel.
