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.

Great for using behind me on Zoom calls
Color: Black, Size: 1 Large Panel
This works great as a place to put tapestries behind me when I'm on Zoom calls... much nicer than blurring out the background. Easy to put together, large, works great.

Good quality, very adorable solution.
Color: Black, Size: 1 Large Panel
Easy to put together and take apart. Wish it had a storage bag of some sort—that would be very helpful. Used it for our mom while she was on hospice at home. The wheels made it very easy to move around as necessary. Nice and tall and wide for privacy. Highly recommend.

Nice, large room divider for privacy
Color: Black, Size: 1 Large Panel
Easy to assemble. Fabric screen covers the large frame very well and provides privacy by separating spaces. I would not exactly call it sturdy, but it does the job and stands freely with no problem. It’s lightweight and portable if you need to move it. Came with a screwdriver and wrench tool for assembly.
