In order to achieve the most brilliant straight mute sound, Soulo Mute uses the highest quality aluminum and copper. Although copper bottom mutes are known for their heavier weight, the Soulo is lightweight due to its craftsmanship. The mute will never fall out of the bell because of its unique neoprene composite corks which "lock" the mute inside the bell. Features:
• Patented hemispherical bottom with crimp-free connection, which allows for a perfect pitch.
• Free-blowing, no air disturbance, aerodynamic design.
• The highest quality copper delivering a brilliant sound.
• Lightweight and super easy on the chops.
