soulo sm8525 trumpet harmon style wah wah mute soulo mute the new copper bottom trumpet harmon style mute, by soulo is the newest invention in the trumpet harmon mute world. the most prestigious music magazine in europe, sonic magazine, calles it "the best harmon mute on the market". the reason for this overwhelming success is the combination between a traditional harmon mute sound and ground-breaking aerodynamic shape. this patent-pending shape improves the typical issues, associated with metal harmon mutes. trumpet harmon mutes, also known as wah wah mutes, are a category of mutes, whose name is derived from the harmon company. these mutes typically produce a buzzy sound and heavy back-pressure, combined with poor pitch, especially in the lower register. in contrast, soulo mute’s design allows the air to naturally flow inside the mute, undisturbed by a crimp or other barrier. this leads to a vastly improved, near perfect pitch, down to the low g, and a free-blowing experience. in order to achieve the dark, buzzy trumpet harmon mute sound and keep the mute free-blowing, soulo mute uses the highest quality aluminum and copper. soulo harmon style mute is very lightweight, in contrast to all other copper trumpet harmon mutes. soulo mute achieved this important feature by using copper only in the bottom half, where it matters. the soulo wah wah mute will never fall out of the bell and embarrass you in the middle of a performance! its unique neoprene foam composite gasket “locks” the trumpet wow wow mute inside the bell nicely. soulo mute did away with the heavy bulky stem and instead designed an light weight injection molded custom sized polycarbonate stem to accompany the mute, to allow for the the “wah-wah” effect. this stem will only work with soulo mutes, it will not fit any others!
