Grover Mini Roto-Grip 505 Locking Tuners 3 Per Side 18:1 Gear Ratio

A smaller version of the regular size Grover ROTO-GRIP lockers for the in line and smaller headstocks or for those who prefer a lighter feel.

Instead of the traditional post lock located on the end of the string post, this set has a convenient locking knob located on the back of the tuner housing keeping the face of the headstock clean while offering superior string locking stability.
