Description

For guitarists seeking precision and reliability, the Grover 18-1 Tuners are a game-changer in the world of tuning machines. Crafted with the modern musician in mind, these tuners boast an 18:1 gear ratio, offering unparalleled control over your guitar's pitch. This higher ratio ensures smoother, more accurate tuning, allowing you to maintain rock-solid tuning stability whether you're on stage or in the studio.

The Grover 18-1 Tuners come with an oversized housing and a 25/64" post hole, making them perfect for accommodating heavier gauge strings. The longer 28.2 mm post provides ample winding room, reducing slip and ensuring your strings stay secure. A countersunk tension screw allows you to adjust the tension to your preference, giving you a custom feel that suits your style. Whether you're diving into intricate jazz phrases or bending bluesy notes, these tuners deliver a smooth, backlash-free experience.

Each set includes three right and three left tuners, along with washers, bushings, and wood screws, making installation a breeze. With a design that pays homage to the classic Rotomatics while incorporating modern enhancements, these tuners are both a nod to tradition and a leap forward in tuning technology.
