The PS-8400-00 is a great option to upgrade or replace the existing saddles in your ABR-1 style tune-o-matic bridge. These are a drop in replacement making for a quick and easy install.
String Saver Original saddles are made with a unique combination of materials made to enhance tone and dramatically reduce string breakage. Each saddle is impregnated with PTFE, the slipperiest substance on earth. The PTFE 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.
