Roto - Grip Locking Rotomatics® use the well - known 18:1 Rotomatics® design. With a 'thumb screw' mechanism, you can easily lock the string in place.

The set comes with all necessary mounting hardware. Features include a set of 6 tuners, an 18:1 ratio, and a beautiful gold finish.

Using these tuners is a breeze. First, insert the string through the post hole on the tuner. Then, wrap the string around the post once. After that, use the thumbscrew to lock the string firmly in place. This will keep your guitar in tune for longer. When it comes to installation, make sure to use the included mounting hardware. Check that all screws are tightened properly to ensure the tuners are secure. As for maintenance, keep the tuners clean. You can use a soft cloth to wipe away any dust or dirt. Avoid using harsh chemicals as they might damage the gold finish. If you notice any issues with the tuning or the locking mechanism, it's best to have a professional guitar technician take a look.
