Edgy with a loud, meaty buzz, the tenor trombone bubble mute offers a wonderfully distinctive sound unmatched by any other. Its large, bubble shape produces free-blowing sound in all registers and it fits all tenor trombone bells. The Jo-Ral TRB-3 Tenor Trombone Bubble Mute has a unique shape and spun aluminum construction that give it a distinctive tone especially desirable for jazz musicians. 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.
