|The Silent Brass system lets you play your horn anywhere you want, anytime you want, and with just the kind of ambiance you feel like. You can mix into the sounds of a CD player, a Silent Piano, an electronic keyboard or other Silent Brass, and output your playing into a tape deck or even an amp with speakers. This redesigned edition edition has evolved through innovative advances in sound technology and construction, offering a more comfortable and realistic experience than ever. The smaller, lightweight design of the new pickup mute offers outstanding sound reduction and provides a natural playing feel. The mute features Brass Resonance Modeling, a leading-edge technology that delivers superior and realistic brass instrument sound.
