The Best Brass Junior Warm-up practice mute is the younger brother of the standard Best Brass mute in plastic form.
Like its brother, it reduces instrument output to a whisper, losing approximately -25dB to -35dB. With this high level of sound reduction, players have no hesitation at home with neighbours, or in hotel rooms. It becomes possible to do long tones virtually silently backstage, or even gear up for that high section.
