L Cups
The L Cup has a lower alpha angle, increased depth, slightly more volume than the MX Cup, and a #3 Backbore.
Although this mouthpiece is excellent on the C trumpet, many players prefer the vibrant feel of it on the Bb trumpet.
The sound presence is around you where the MX cup projects with a sound that is more direct.
This cup plays very evenly throughout the registers and the sound is rich with resonant overtones.
Preferred for Concert Band, Wind Ensemble, Brass Quintet, Chamber Work, Orchestral Work, Solo Work, and Jazz.
