The largest, free blowing Schilke Bb trumpet available.
The X4 Traditional Custom Series trumpet is the largest, free blowing Schilke Bb trumpet available. The extra-large bore and large throat bell makes this trumpet extremely open, with a large sound and excellent projection.
The X4 trumpet is available in three variations—a fixed yellow brass bell, a fixed beryllium copper bell, and a tunable yellow brass bell—each designed to customize the instrument performance to the player.
