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, the standard use is for small-shank tenor or alto trombones, but I'd like to suggest another way to use it. When I couldn't even squeak out a high Bb, I experimented with a small mouthpiece I found in the music room, and it helped me understand how to breathe to produce high notes. # Once I understood, I could easily reach high D, and high F came quickly. Players with large-shank trombones will need to purchase an adapter separately, but if you struggle with high notes, I recommend trying a small mouthpiece for a little experimentation. # In other words, I recommend it for that kind of use as well.
