Super-Vee SuperGlide Nut Lubricant
SuperGlide is a new guitar nut lubricant that is far superior to existing "nut lubes" for eliminating excessive friction that prevents stable tuning in tremolo bar systems. In fact, even in non-trem guitars, SuperGlide improves the ease and accuracy of tuning.
SuperGlide is made by Super-Vee, the company that makes the revolutionary Strat vibrato systems. SuperGlide actually accumulates and gets better the more you use it, becoming "bonded" with the nut surface, whether it is bone, plastic, etc.
