W.H.F.-Trombonemouthpiece-Cup O/CS 4 -heavy- diameter: 25,25 mm The shortest mouthpiece in the open series impresses with its light height and clear, bright tone. A 7.2 mm bore allows for very comfortable airflow. To round out the sound, we recommend the larger back holes A5, B5, and C5. The O before the slash stands for open series and is especially recommended for American-style trombones. The larger bore of this mouthpiece series takes into account the wider bore of these instruments.
