The PS-8615-07 is a great option to upgrade or replace the existing saddles on a 7-string Tune-o-Matic bridge marked SUNG IL BM002, TonePros AVR-II, S.I.C., or Komax.
The image below shows 6 of the 7 saddles set.
String Saver Original saddles are made with a unique combination of materials 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 more significant portion of the string, just enough to drastically reduce string breakage.
