He said grover locking tuners, the ones from the pre-schaller days, which actually were kind of a pain, and not nearly as easy to use as the rear screw shallers you all seem to be referring to, so quit giving the poor guy a hard time.
Here's some instructions I ninjad from another site. Man a I glad Eb ditched these PITA tuners!
Grover Locking Tuners
1. Lay the guitar on a firm, flat surface with the peg head to your left.
2. Place the string between the screw head and spacer.
3. Grip the string firmly with your left hand and bend it around the post toward you to a 90 degree angle. (Note: Do Not wrap the string completely around the post.)
4. While maintaining your grip on the string use the supplied Grover tool (or coin) and tighten the screw just enough to hold the string in place (Fig.1)
5. Now hold the tool (or coin) steady while turning the tuning peg counterclockwise 5-6 half turns. (Fig.2) (Note: Do Not over-tighten! This should be enough to lock the string in place.)
Once you have mastered the "art" of changing strings you still need to master the "art" of choosing the right strings, hehe so... once your blue steel have de-cryogenicalized (i.e. worn), get some Ernie Ball coated best brand in the world
