Manufacturer's description:
‘Made of high quality spun aluminum, and tested to perform evenly in all registers, the Jo-Ral tenor trombone bucket mute provides a truly distinctive sound. Deeply haunting and slightly hollow, its soft, muffled tones add tremendous dimension, and its unique straight shape allows for quick transitions. The mute features 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.’
The bucket mute, also known as the velvet-tone (or velvetone), is like an upturned can filled with sound-absorbent material attached to the outside of the bell. It originated with early jazz trumpeters, and produces a soft, smooth sound. Some are clipped to the rim of the bell, but this model manufactured by Jo-Ral Mutes is inserted into the bell, allowing a quicker change.
