Every drumming needs a drum key handy at all times, and now Pearl has developed a great tool that includes a drum key and another great tool, a flip mute!! In the past drummers would often use their wallet on the batter side of a drum to mute, or soften the overtones for certain songs or feels. This "Flip" system Pearl has developed lets you keep the drum key handy, and flip up the leather to mute the overtones. Add a coin or two in the mutes pouch for more, or less muting.
