Manufacturer's description:
'Designed for versatility in artistic expression, Jo-Ral tri-tone trumpet cup mutes deliver three distinct sounds from a single mute: two removable felt rings can be inserted to successively produce a more mellow sound. Made from spun aluminum, the mutes have been tested to perform evenly across all registers. They also feature neoprene-enhanced composite cork pads that grip well and don’t dry out, become brittle or break off, and so last longer while easily accommodating fine adjustments for a perfect fit."
Cup mutes are similar to straight mutes (cone-shaped with three corks) with an added 'cup' facing the bell of the instrument. Most are adjustable, allowing the distance between the cup and the bell to be modified. They produce a more subdued tone than straight mutes, reducing both lower and higher frequencies, and offer colours much favoured by jazz musicians.
