This is a genuine synchronized tremolo made in Tokai, from the Tokai SPRINGY SOUND series. The saddle is stamped "TOKAI" instead of "FINAL PROSPEC," so it's from before 1980. The string spacing is 11mm, and the block and plate are one-piece. There are scratches, dirt, discoloration, deterioration of the metal plating, and minor rust. There are no issues with sticking or operation, and it looks cleaner in person than in the images. A valuable genuine arm, mounting screws, and springs are included. #Tokai GOLDSTAR SOUND #SILVER STAR
