KIND OF BLUE
The Harmon Trumpet Wow-Wow Mute is a favorite effects mute, especially for jazz trumpeters. The "wah-wah" sound is made by a sliding cup in the end of the mute. Miles Davis' legendary tone on All Blues, and other classic cool records feature this unique mute.
Made entirely of spun aluminum, the Harmon Trumpet Mute is free-blowing and does not alter or change the pitch.
