Jo-Ral Mutes Jo-Ral Mutes

FRC All Copper Non-Transposing Straight Mute

With a delightfully more mellow finish than traditional aluminum models, the All Copper French Horn Straight Mute allows for a free-blowing sound in all registers, providing a consistent flow quality that allows musicians to achieve a delicate, controlled sound without transposing registers.

The Jo-Ral FRC All Copper Non-Transposing French Horn Straight Mute is crafted entirely from copper, producing a powerfully dark and rich sound. 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.
