This entire range of quality brass mutes are a must for any gigging amateur or pro! They are made from a strong polycarbonate material and can sustain the hardest of knocks, in fact the manufacturer states that they are indestructible. The sound they produce is extremely good and clean and can compete directly with more expensive brands. Several of my brass playing colleagues (and I) have tested these and were thrilled with the tone and how easy they were to play through!

This particular mute is even more clever as it has a sliding cup which can be moved up and down to create a variety of different sounds,or removed completely for use as a straight mute!   Brilliant!
