Wilkinson WJN03 EZ-Lok Guitar Tuners 1:19 Ratio for Epiphone LP SG

In this review the Wilkinson WJN03 EZ-Lok set is judged as a practical, low-cost replacement for Epiphone Les Paul and SG owners who need more reliable tuning without changing their instrument's look. The bottom line: these are straightforward, full-metal 3L3R machine heads with a 1:19 gear ratio and the E-Z-LOK winding post that helps strings stay in tune with fewer wraps, making them a sensible upgrade for players who want improved tuning stability and a factory-correct fit.

Key Features

• Direct fit for many Epiphone models: Designed to fit 10mm (25/64 in) peg holes and 45 degree screw hole spacing so installation matches common Les Paul and SG layouts.
• E-Z-LOK post: The E-Z-LOK post simplifies string changing and reduces slippage by allowing the string to lock under itself for better tuning retention.
• Accurate gear ratio: The 1:19 gear ratio delivers fine incremental adjustments so tuning is precise and predictable.
• Complete hardware kit: Each set includes washers, bushings and mounting screws, which means no extra small parts are required for a standard installation.
• Solid metal construction: Full-metal housings and kidney bean style buttons offer durability and a traditional aesthetic in a black finish.
• 3x3 configuration: The 3L+3R layout preserves the classic headstock balance used on Les Paul and SG models.

Who It's For

These tuners are best for Epiphone Les Paul and SG players, or owners of similar electric and acoustic guitars, who want a like-for-like replacement that improves tuning stability without converting to modern locking tuners. Players who prefer a full-metal, vintage-style look and precise 1:19 tuning control will appreciate this set.

They are not for someone who requires true locking tuners for rapid string changes under heavy gigging conditions, since these are not real locking tuners even though the E-Z-LOK post helps reduce slippage. Also check measurements before buying if your instrument uses nonstandard post heights or hole diameters.

Pros & Cons

Pros

• Good compatibility with Epiphone-style 10mm peg holes and 45 degree screw spacing for straightforward installation.
• E-Z-LOK posts make string winding neater and reduce the number of wraps needed for stable tuning.
• 1:19 gear ratio offers accurate, smooth tuning adjustments.
• Includes washers, bushings and screws so the set arrives ready to install.

Cons

• Not actually locking tuners, so they lack the convenience of true locking mechanisms for very fast string changes.
• All E-Z-LOK posts use the same "M" height post which may require a string tree on some headstocks to achieve correct string angle.
