Grover Rotomatic Guitar Tuners Locking Chrome 3+3

Grover Rotomatic Guitar Tuners Locking Chrome 3+3 

Fast string changes and non-slip tuning! Rear thumbscrew locks the string for non-slip tuning and fast string changes. For 3-left/3-right pegheads.

Traditional Rotomatics® with a twist! Simply wind the string once, tighten knob, and tune to pitch! You’ll need fewer string wraps, change strings faster, and your tremolo will have more accurate return-to-pitch.

For 3-left/3-right pegheads only.
