Manufacturer's description:
"Made of high quality spun aluminum, and tested to perform evenly in all registers, the Jo-Ral tenor trombone cup mute allows the sound to bounce back towards the instrument bell producing a smooth, rich sound and a dark, full-bodied tone.
The mute features neoprene-enhanced composite cork pads that provide extra durability. The result is a more pliable cork that grips well and doesn’t dry out, become brittle or break off, so it lasts longer while easily accommodating fine adjustments for a perfect fit."
