Buying Guide

Locking vs. non-locking

Locking tuners simplify string changes and improve tuning stability; choose locking models if you want quicker restringing and less slippage

Gear ratio matters

Higher ratios like 1:18 provide finer tuning control—useful for precise adjustments and maintaining stable pitches

Headstock fit and post size

Verify compatibility with 10mm post or your guitar’s headstock layout (3L/3R or 6-in-1) to avoid drilling or adapter needs

Material and finish

Chromed hardware resists corrosion and matches many instrument aesthetics; consider finish to match existing metal parts

Included tools and extras

Tuners that include installation tools (hex handles) or full 6-piece sets reduce the need for separate purchases and simplify installation
