"A new bridge with improved bent steel saddles and a copper infused high mass block for increased sustain and resonance". Very nicely made. Chrome plated steel two point bridge plate, copper infused steel intertia block with silver lacquer finish, vintage style bent steel nickel plated bridge saddles stamped "FENDER FENDER". I measured 2.119" E to E. Fits on the American Series pivot studs already on your guitar. You can also use your old American Standard whammy bar and saddle height adjustment wrench. Brand New.
