Price reduced on 2025.09.04. ----- This is a willie's Custom Brass mouthpiece, Walküre. Please note that it is for a small shank. I used it for about three months, but then switched to a larger mouthpiece, so it has been unused for about a year. I am selling it to organize my equipment. The size is about the same as a Bach 5G. The shank is clean and fits perfectly on both American (Bach 42B) and German (Jurgen Voigt) trombones. An adapter makes it convenient for switching between small and large shanks, or alto and tenor trombones. The tone changes completely depending on the mouthpiece, but willie's are bright,華やか (splendid/gorgeous), and soft, in my opinion. The Tilz I am selling at the same time is harder and clearer. The product information from the seller is as follows: -------------------- willie's mouthpiece bestseller.
