Jo-Ral B7 Bass Trombone Cup Mutes are made of spun aluminum, and have been tested to perform evenly in all registers, creating an exciting tonal quality that results in near perfect intonation.

Jo-Ral mutes also feature 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.
