Wmutes Cello Concert Mute Gold BrightThe concert mute by Wmutes is specially designed to produce a high quality muted sound for your instrument. The amount of muted sound is similar to a standard mute, but its design and materials produce a much richer, stable and focused sound. Made of an especially refined bronze, Wmutes are plated by gold (1mc 24k), ruthenium or silver with the same sound quality. Choose also between a mate or bright finished of the piece.
