The se saddles serve as a direct replacement for TonePros T3B or T3BT tune-o-matic bridges, like those found on ESP 400 and 1000 series guitars, many Schecter guitars, and lots of other instruments.
String Saver Original saddles are made with a unique combination of materials made to enhance tone and reduce string breakage. They are impregnated with PTFE, which reduces the friction between the saddle and string and provides self-lubrication to reduce string breakage. The material used provides a very balanced tone across the spectrum.
