The temperament strip is used to mute all the outside strings of a section at once, so that only one string from each note can vibrate at a time. You may need a screw driver to push it between strings.
These 3 rubber wedge mutes are used for more easily muting other strings of this section. One felt mute is designed for the left section.
High quality mute clamp and 1 rubber mute with handle works great on the right section!
