The hand-spun aluminium is both light and extremely resonant. Other manufacturing techniques produce mutes which are not as hard. Our hand-crafting produce a mute where the metal is 'work-hardened' making it both light and very resonant. This makes it free-blowing and extremely responsive and the choice of the most demanding musicians.
Real cork is used to produce a snug fit in the bell of the instrument. We are proud that this mute is used by thousands of musicians all over the world and yet also represents incredible value. This is one of the most important pieces of equipment a trumpet-player will ever purchase, but is available at an incredibly reasonable price. -the manufacturer
