Price reduced on 2025.09.15. ----- This is a small-shank mouthpiece purchased for an alto trombone. It's a 48A, which has a shallower cup than the more common 48. I think it's characterized by bright, light high notes. I'm selling it to organize my equipment. It comes with the original box. Of course, it's the standard to use it on a small-shank tenor or alto trombone, but I'll suggest another way to use it. When I couldn't even squeak out a high Bb, I tried using a small mouthpiece that was lying around in the music room for fun, and I understood how to breathe to play high notes. # Once I understood, I could easily reach high D, and high F came quickly. Those with large-shank trombones will need to get an adapter separately, but for those who struggle with high notes, I recommend trying to play around with a small mouthpiece. # In other words, I recommend it for that kind of use as well.
