Really well made locking tuners with the Fender "F" stamped on the back lock-wheel. These are staggered height posts, with 2 heights. The 3 wound strings are higher then the 3 plain strings. The idea is that they'll generate more of a break-angle over the nut, so you can dispense with the string trees where strings get stuck while bending and cause tuning issues. However, the angles they are made to, on a Telecaster and Stratocaster, are still not low enough. You still need the string trees, so they are a bit pointless in that regard. The locking side of things works well though. Whey smooth to use.
