Harmon 197 Trombone WOW Mute

The Harmon Trombone Wow-wow Mute is a favorite effect mute. Famous musicians have used and endorsed Harmon mutes for over 25 years. The wah-wah sound is made by a sliding cup at the end of the mute. Made entirely of aluminum, this mute is free-blowing and does not alter or change the pitch in any way.
