Fender Pure Vintage Bass Tuning Machines, Set of 4

This is a set of four nickel-plated tuning machines with a vintage style. They are perfect for most modern and vintage Precision Bass® and Jazz Bass® guitars, though they won't fit American Standard and American Deluxe basses. The set comes with mounting hardware. Key features include a 26:1 gear ratio, 'Clover'-style keys, and a reverse-action (counterclockwise) design.

Using these Fender tuning machines is easy. First, make sure your bass is not an American Standard or American Deluxe model as these tuners won't fit. Then, use the included mounting hardware to install the tuners on your guitar. When tuning, turn the 'Clover'-style keys counterclockwise due to the reverse - action design. The 26:1 gear ratio allows for precise tuning. As for maintenance, keep the tuners clean by wiping them with a soft, dry cloth regularly. Avoid using harsh chemicals that could damage the nickel plating. If you notice any issues with tuning or the movement of the keys, it might be a good idea to have a professional check them out.
