These are genuine Fender American Pure Vintage 50s/60s Kluson style Logo tuners in mint condition. These came from a '23 American Vintage II '66 Jazzmaster but they're also the same ones used on the previous models and many of their American Vintage 50's and 60's Telecasters, Stratocasters and Jaguars to name a few. These are manufactured by Gotoh in Japan and are of the highest quality with a 15:1 ratio. These are also non-staggered and included the mounting bushings and screws. An awesome upgrade for your Mexican and import models!
