Bremner Sshhmute Trumpet/Cornet Practice Mute
The primary benefit of the sshhmute design is the very small amount of back-pressure it creates. Most practice mutes change the resistance significantly. With Sshhmutes, the player experiences virtually no change in resistance, making practice a really valid exercise. The mutes allow for better air supply, while still opening and developing the throat muscles. The mute also remains in tune and faithfully accurate throughout the entire range.
