Grover 135N Deluxe Vintage Guitar Tuning Machines Nickel Set 3+3

In this review of the Grover 135N Deluxe vintage guitar tuning machines, the bottom line is simple: these are a targeted upgrade for players who want authentic vintage styling with reliable mechanical performance. The set is a direct 3+3 replacement for LP Les Paul style pegheads and the standout reason to buy is the combination of a die-cast, two-piece housing with a 14:1 gear ratio that gives stable tuning and a classic look. The bundle also includes bushings, screws and a Dunlop polishing cloth so installation and finishing touches are straightforward for the hands-on player.

Key Features

• Vintage styling: The green keystone button and nickel finish deliver an authentic look that matches classic Les Paul style instruments.
• Durable housing: Die-cast two-piece housing provides extra strength and a bearing surface designed to keep the string post stable and aligned over time.
• Precise gearing: The 14:1 gear ratio gives fine tuning control so players can make small pitch adjustments with confidence.
• Drop-in replacement: Designed as a 3 left / 3 right set for LP style heads, it fits new installations with the included hardware for a clean upgrade.
• Complete bundle: Comes with bushings, screws and a Dunlop polishing cloth so the tuners arrive ready for installation and final polishing.
• Post dimensions: Long posts and a 25/64 in post hole size accommodate thicker nuts and some rollers for heavier string gauges up to.074.

Who It's For

The Grover 135N set is best for guitarists who own Les Paul style instruments or other 3+3 headstocks and want a period-correct upgrade that improves tuning stability without altering the guitar's visual character. Luthiers and hobbyists who prefer to fit hardware themselves will appreciate the included screws and bushings and the need to drill only a new top mounting hole in some older models.

Players who need a sealed modern locking tuner or gear ratios higher than 14:1 for ultra-fine microtuning should look elsewhere. Also, this set is not suitable for 6-in-a-row headstocks or designs that require different post hole sizes without modification.
