6 In-line Guitar Locking Tuners Pearl Buttons - 1:18 Gear Ratio

In this review the reviewer looks at the 6 in-line guitar locking tuners with elegant pearl buttons and a precision 1:18 gear ratio. The bottom line: these tuners are a practical, affordable upgrade for players who want more stable tuning and a neater headstock appearance without replacing the whole instrument. They suit many electric, folk and acoustic guitars and stand out for their sealed lubrication, sturdy cast housings and included mounting hardware that makes installation straightforward.

Key Features

• Locking mechanism: Locking pegs hold string ends securely to reduce slippage and speed up restringing on most modern headstocks.
• 1:18 gear ratio: The high-precision ratio gives finer tuning control for accurate pitch adjustments.
• Sealed lubrication: Sealed gears arrive ready for use and stay smoother over time for consistent tuning stability.
• Included hardware: Screws, bushings and washers are supplied so the set can be installed without buying extra parts.
• Pearl button finish: Pearl white buttons add a tidy decorative touch to the headstock while remaining comfortable to turn.
• Cast housings: Metal housings and knobs provide a more durable feel than thin plastic alternatives.

Who It's For

This kit is for players who own electric, folk or acoustic guitars with modern headstock peg holes roughly 10mm in diameter and who want an inexpensive route to improved tuning stability and easier string changes.
