Best Brass Trumpet Mouthpiece 7E Gold Plated Finish

In order to embody the ``great trumpet sound'' that Best Brass envisions, we designed it to be slightly heavier. In addition, the two acoustic slits that emphasize its unique design achieve both long-distance sound transmission and flexibility. It promises a profound sound, long range, and a dignified ``trumpet-like tone.'' You'll also be surprised at the playing feel, which you wouldn't expect from a heavy type. Rim width: 5.823mm. Rim inner diameter: 16.25mm. Cup Depth: Shallow. Throat diameter: 3.78mm. Backbore: TP-M.
