Another of Denis Wick's most popular mutes. A great practice mute with limited back pressure.

"Not only do they(DW practice mutes) fulfil the need for the IN TUNE painless practice, so essential in the development of every young player and an indispensible 'hotel mute' for the professional, but they also make possible an enormous improvement in tone quality using the entire vital capacity as a vibrating air column by opening the throat spaces through playing loudly in the low register."-Denis Wick
