I was so excited to get to your package today, much sooner than I had expected. The smaller Etude fit the slide I already had on my clarinet, so I tried it right away. It’s terrific! It’s comfortable and, even better, I can hear a marked improvement in my tone, something I didn’t expect. Thank you so much for this and for the others, which I am also very glad to have. And thank you, too, for including the spare rubber piece, which looks like it might fit the Etude 1 rests, too. You’re so good! Thank you for being so kind to me! I will think of you every time I play, which looks like it’s going to be for many more years.
