Brass lacquered, detachable bell 126 mm, soldered, wire-reinforced rim, 11.7 mm ML-bore, Monel valves, 2 interchangeable lead pipes, adjustable mouthpiece receiver for customizing the "Gap," crafted here in Germany. Includes double bag and mouthpiece.

The term "Gap" in trumpets refers to the small space between the end of the mouthpiece and the beginning of the lead pipe inside the mouthpiece receiver. This distance may be minimal, but it has a significant impact on the playing feel, response, and sound of the trumpet.

A larger or smaller Gap affects airflow and resistance within the instrument:

• Larger Gap: Increases resistance, often resulting in more stable tone control but may require more effort to play.
• Smaller Gap: Reduces resistance and can improve response but may sometimes result in less stability in tone control, especially in higher ranges.

Some trumpet players experiment with various mouthpieces and Gaps to find the optimal balance of sound, response, and playing feel.
