Best Brass Trumpet Mouthpiece 7X Gold Plated Finish

In order to embody Best Brass' image of a "great trumpet sound," this trumpet is designed to be slightly heavy. In addition, the two acoustic slits that emphasize the unique design provide both long-range sound and flexibility. You are guaranteed to get a profound sound, long-range sound, and a dignified "trumpet-like tone." You will also be surprised by the blowing sensation, which is hard to believe for a heavy type. Rim width: 5.823mm. Rim inner diameter: 16.25mm. Cup depth: Very deep. Throat diameter: 4.5mm. Backbore: TP-X.
