Adjustable cup mutes offer a huge range of creative possibilities. Our Bb/C trumpet adjustable cup mute allows you to recreate soundscapes from vintage straight, through classical cup, to tight cup, all the way to a bucket sound. And you can blend those sounds depending on the cup position. Set the sound you want with a simple twist and you're ready to go. Opt for a looser fit and you can change the sound whilst you solo; imagine a call & response with yourself just from a simple twist! - the manufacturer
