The 5524 Denis Wick mute offers an amazing range of tone colors to any brass section and is essential for the performance of a huge range of musical styles. The hand crafting of these mutes gives the high-quality aluminum a "work hardened" quality, which makes for a very resonant product that will give a wonderful fortissimo when it is needed. The mute is designed to work in all registers, so even the very difficult low notes work perfectly. Made from high purity spun aluminum, "scotchbrite" finished and bright silver anodized. This mute is widely respected amongst professionals as it has excellent intonation and is well matched when played together in a section. Made in England.
