Nut Sauce also stops wear and tear at the bridge and nut, increases sustain and harmonics, and improves overall playability of any stringed instrument. Don't be fooled by knock-off imitations. The concept of Nut Sauce is simple. Use it to stop the string drag or friction at the nut and string guides. Reduce string breakage at the bridge and saddles by reducing friction and wear from the see-saw action of hard playing, especially with a thick pick. Well, it's no secret that guitar players for years have used pencil lead, Vaseline, lip balm, and many other things to help keep their guitars in tune. With a technical background that extends to lubricants, Big Bends approached the problem with a scientific perspective and finally created Big Bends Nut Sauce!. The criteria was simple - it had to be non-toxic, non-corrosive, created with state-of-the-art lubricants, could not affect the finish of your guitar, and had to be so thick that it would stay where you put it (that means in the nut slots, under the string guides or on the bridge or saddles). NUT SAUCE meets this criteria and more.
