One of the best trumpet mutes for jazz work on the market for many years.
The Harmon L Model Wow-wow is a favorite trumpet effects mute. The "wah-wah" sound is made by a sliding cup in the end of the copper mute. Famous musicians have used and endorsed Harmon mutes for over 25 years. Made entirely of lacquered copper, the L model mute is free-blowing and does not alter or change the pitch in any way.
