Who the K3491B Cornet Mouthpiece Is For
The Bach K3491B is a Megatone-series cornet mouthpiece designed for players who want a darker sound, a warmer feel, and lower resistance than many standard-mass mouthpieces. With its medium deep 1B cup and medium-wide rim, it suits cornetists looking for a stable, supportive rim contour while maintaining flexibility across dynamic ranges.
What distinguishes the Megatone design is the added mass and a slightly larger throat, which together can reduce perceived resistance and support a broader, more powerful tonal center. This makes the K3491B a practical choice for jazz and symphonic settings where a darker color and stronger fundamental are preferred.
