NEW - Set of 6 Graph Tech String Saver PS-8166-00 I.O.S. Round Bridge Saddles For Tele Length - .411", 10.44mm Width - .300", 7.62mm Height - .300", 7.62mm E to E - 2.209", 56.11mm I.O.S. barrel saddles have been designed for Vintage Tele style guitars. I.O.S. saddles open up string vibration by changing the string contact point on the saddle. Strings are allowed to oscillate more freely, allowing for a fatter, more open sound, increased sustain and the elimination of the “sitaring” effect. I.O.S. barrel saddles are an important upgrade for any guitarist seeking improved performance from a Tele style guitar. Why String Savers? Metal saddles hold your stings firmly. Too firmly. Imagine tightly gripping a wire coat hanger and bending it back and forth, over and over – it snaps. Patented Graph Tech String Saver saddles ease this grip. 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. Teflon is 500% more slippery than graphite and is impregnated throughout the String Saver material, so its lubricating properties will never wear out. For string breakage reduction the difference can be dramatic. Strings that last and last, no matter how hard you play – they guarantee it.
