This 6 In-Line set of Kluson tuning machines was used on all vintage 6 in-line Fender Strat, Fender Tele and many other models of Fender instruments. This model Kluson tuning machine is also a direct replacement for all current re-issue 50's and 60's Fender production and Fender signature series that utilize a split post (safety post) vintage style tuning machine. "Kluson Deluxe" stamped on the casing in a single row, as per originals. These are six individual tuners (not on a plate). All hardware including bushings and mounting screws are included in the set. Please note: If you are retro-fitting a vintage instrument that has been modified or putting this vintage style tuning machine on a modern instrument you may also need to purchase the part MB65LUS "adapter bushings" to convert a larger size peghole to vintage size to allow for proper fit and function. Tuners available in Nickel, Black and Gold finishes (standard right handed) and Nickel or Gold (left handed). Supplied with 8.8mm outside diameter push-fit vintage bushings with 1/4 inch inside diameter.
