String Saver Originals Strat & Tele 2-1/16" Spacing are a unique combination of materials made to enhance tone and dramatically reduce string breakage.How do they work? A string resting on a metal saddle binds and locks the string in place. As the string vibrates, it stresses the string on a very specific point producing metal fatigue and then string breakage. Each String Saver saddle is impregnated with Teflon, the slipperiest substance on earth. The Teflon in String Savers eases the grip between the saddle and string, spreading the stress over a greater portion of the string, just enough to drastically reduce string breakage. Teflon is 500% more slippery than graphite and is impregnated throughout the String Saver material, so its lubricating properties will never wear out.
