I went to The Valve (a great brass instrument shop in London) today, to look at cases and buy a harmon mute. Also, I ordered a “triple” case which will hold both a trumpet and a flugelhorn.
I found myself looking at mouthpieces and bought a very intriguing one made of transparent polycarbonate. It’s unbreakable, won’t get stuck in the leadpipe and always feels warm to the lips. Here’s a picture of it.
