Mute for classical guitar strings as well as for five-string electric bass, it prevents the production of harmonics and various resonances/noises making it an ideal aid for recordings and live performances while being an important addition for guitarists who do two-handed tapping. Additionally, it is an ideal solution for cutting off the noise created by the strings when playing. The Gruvgear string mute is adjustable so we can determine the pressure we want to apply to the strings.
