Probably the most popular cup mute we sell. Made of aluminum with soft interior, the Denis Wick has an adjustable cup so that the performer can change from a quieter closed sound to a more open and projecting sound. Great for musical theatre work. "This is by far my favorite mute.You get so many different cup mute sounds from your classic open Stone Lined sound to a smooth modern jazz sound. You can also push the cup all the way to the bell and play it like a bucket or practice mute. And because it's adjustable, it'll fit in any bell, you never have to worry about filing corks down."
