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, other Silent Brass or other instruments with electronic output such as Clavinovas, Silent Pianos, synthesizers or electronic keyboards, and output your playing into a tape deck or even an amp with speakers. Never again will you have to search for a practice room, have to "stop because it?s getting late". The Silent Brass system includes Personal Studio, Pickup mute, earphones, and an adapter. Separate Pickup Mutes are also available.
