Guyker Guitar Locking Tuners 6 for Left - Precision 1:18 Gear Ratio

In this review the Guyker Guitar Locking Tuners are evaluated for players who need a reliable, easy-to-install replacement set for Strat, Tele, SG or Les Paul style headstocks. The bottom line: these tuners deliver smooth, precise tuning thanks to a 1:18 gear ratio and sealed lubrication, and they are best for players who want an upgrade that fits modern 10mm peg holes without major modification. The review focuses on build quality, installation, and whether the locking feature performs as expected.

Key Features

• Precision 1:18 gear ratio: Provides fine, stable adjustments so strings hold pitch more accurately during playing and bending.
• Sealed lubrication: Keeps the internal gears running smoothly and reduces the need for maintenance over time.
• Cast housings and metal knobs: Give a solid, durable feel that resists wear from repeated tuning.
• Hexagonal button and 45 degree fixing tag: Improves grip and alignment, making installation and tuning more comfortable.
• Mounting hardware included: Screws, bushings and washers come with the set so replacement is straightforward without sourcing parts separately.
• Designed for modern 10mm holes: Fits Strat-style headstocks and many contemporary guitars with minimal or no modification.

Who It's For

These locking tuners suit gigging and practice players who want a compact, high-ratio set that keeps an electric or acoustic guitar in tune. The 1:18 ratio and sealed gears make them a good match for lead players and anyone who frequently bends strings or uses a vibrato system and needs stable tuning.

Players who need vintage-spec parts, non-locking classical tuners, or non-standard peg diameters should look elsewhere; this set is specifically designed around modern 10mm headstock peg holes and a locking-style configuration rather than vintage open-gear designs.

Pros & Cons

Pros

• Smooth, precise tuning from the heavy duty internal gear and 1:18 ratio.
• Durable cast housings and metal knobs feel solid and long lasting.
• Easy installation with included screws, bushings and washers for most modern guitars.
• Good value and overall look, with a neat gold and black finish that complements many instruments.

Cons

• Lockability has mixed reports; while it works for most strings, some users may experience inconsistent locking performance.
• Intended for modern 10mm headstock holes, so older or non-standard headstocks may need modification or different tuners.
