The ideal choice for any musical genre, the Jo-Ral Copper Bottom Bass Trombone Straight Mute produces a smooth, distinct tone.  It is free-blowing in all registers and designed to fit all bass trombone bells. Finished with a copper bottom, producing a powerfully dark and rich sound.

The Jo-Ral TRB-4C is made of spun aluminum, and has been tested to perform evenly in all registers.  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.
