NEW - Set of 6 Graph Tech String Saver PG-8000-0B Bridge Saddles. Too firmly. Patented Graph Tech String Saver saddles ease this grip. Manufactured by Graph Tech. As a string moves and vibrates against a String Saver saddle, a thin Teflon film is created which eases the grip of the saddle on the string and microscopically spreads the stress over a greater portion of the string.
