because my old mouthpiece slowly dissolves (it's veeeery old) and the top layer peels off, I ordered this mouthpiece. I used to advance a short 12T, and have therefore decided to use this. It fits perfectly in my tenor horn and can be played easily. also height-tones are not a problem. Unfortunately, the delivery lasted of 14 days, I find clearly too long. the supplier said it was up to the Post, it was veschickt Warensendung.
