Genuine Fender tuners, as used on many of the American Series guitars (American Standard, American Deluxe, etc). Graduated heights of the string posts eliminates the need for string trees in many cases, reducing friction in the string paths, and helping the strings return to pitch when using the tremolo.
Fender's signature 2-pin mounting allows the tuners to be mounted to necks with this feature in minutes using only a 10mm wrench or socket. Super easy!
