The ideal choice for any musical genre, the distinctive black textured finish, dramatically reduces volume without distorting tone quality, for quiet practice sessions. It is free-blowing in all registers and designed to fit all bass trombone bells.

The Jo-Ral 4A Bass Trombone Straight Mute 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.

Features:

• Fits all bass trombones
• Crafted from lightweight spun aluminum
• Pliable neoprene-enhanced composite cork pads offer lasting durability and grip
• Soft felt cap for extra protection
• Made in the USA
