Harmon L Model Copper Trumpet Wow-Wow Mute

The Wow-wow is a favorite effects mute. The "wah-wah" sound is made by a sliding cup in the end of the mute. Famous musicians have used and endorsed Harmon mutes for over 25 years. Made entirely of aluminum or lacquered copper, they are free-blowing and do not alter or change the pitch in any way.
