The Lubrikit from Planet Waves is a general-purpose instrument lubricant that provides tuning stability by removing friction. As all players know, friction is the root cause of all tuning problems. Apply just a drop of Lubrikit to the nut and tremolo/bridge to optimize tuning stability, combat bass or guitar string breakage, and end premature wear of the bridge and nut of the instrument. Field-tested with the industry's top techs and luthiers, Lubrikit comes with one syringe of lubricant and two application swabs.
