Best Brass Trumpet Gold Plated Finish Mouthpiece, 3C,

To embody Best Brass' vision of a "superb trumpet sound," we designed this instrument to be slightly heavier. Furthermore, the two acoustic slits that accentuate its unique design provide both projection and flexibility. You're guaranteed to achieve a rich, resonant sound with excellent projection and a dignified, "trumpet-like tone." You'll also be surprised by the playability, which is unexpected for a heavy-type instrument. Rim width: 5.823mm. Rim inner diameter: 16.85mm. Cup depth: Moderate. Throat diameter: 3.78mm. Backbore: TP-M.
