Denis Wick tenor trombone aluminum adjustable cup mute

"Denis Wick cup mutes have the perfect intonation that has become the hallmark of all Denis Wick mutes, with the added bonus that the cup position can be adjusted to give exactly the desired sound quality-for microphone, solo, or section playing. The trombone and bass trombone models have absolutely no bad notes and respond evenly in all registers." -Denis Wick. Made in England.
