This is a Brass Evolution tuba mouthpiece, No. 3. It's easy to blow into, and the cup diameter is slightly larger than a Bach 24AW, so how about it for stepping up? 【No. 3】 (Comparison: Conn Helleberg, Perantucci PT83, etc.) Based on the Helleberg model, the throat is large, resulting in less resistance and a bright, clear sound due to smooth airflow. The cup is a medium V-cup. It's bright, sharp, and clear. Airflow is good, and it's easy to produce a large volume. There is no box. It is only the item itself, so it will be wrapped in bubble wrap to prevent scratches before shipping. This is a used item, so no claims or returns are accepted. I'm not good at taking photos, but the actual item is not black!
