The Hawkins Mutes Trumpet Practice Mute.
Plays in tune, and free-blowing whilst still being whisper-quiet. What more do you want from your practice mute??
“The practice mute is an essential part of my life as I live (and teach) in my apartment sometimes. This is the first and only practice mute I’ve ever blown that blows the same intonation as when I’m open. The resistance is also very comfortable, and when I play open again I feel really good with no adjustment. I don’t know how you did it Tony but it’s changed my playing life!”
