The Pickup Mute together with the Personal Studio power supply and signal processor form a muting system for brass instruments. It allows musicians to play anywhere with a natural instrument feel. The Pickup Mute quiets the instrument’s sound to the level of a whisper, while the Personal Studio lets musicians hear their performance through headphones with such a sense of immediacy that it is easy to forget they have a mute in place at all. The system can be used for trumpet, flugelhorn, trombone and French horn.
