Kluson Revolution Diecast Tuners - Pearloid Keystone Buttons

In this review the Kluson Revolution Diecast Tuners are evaluated for players seeking a direct, high-quality upgrade to factory tuners. The bottom line: these locking tuners combine a 19:1 high gear ratio and a rear locking clamp to deliver noticeably improved tuning stability and easier string changes, while keeping the traditional Kluson footprint so they fit many guitars with minimal modification. They are sold as a set of six and include all mounting hardware, making them a practical choice for someone who wants a reliable retrofit without changing headstock drilling.

Key Features

• Locking mechanism: The rear knob clamp secures the string in place for faster string changes and reduced slippage during play.
• High gear ratio: The 19:1 ratio provides fine, smooth tuning adjustments and minimizes backlash for stable tuning.
• Die-cast housing: The sealed one-piece housing protects gears while maintaining a traditional outline with a modern appearance.
• Complete hardware: Mounting screws and headstock bushes are included so the set is ready to install out of the box.
• Retrofit design: Intended to directly replace many die-cast tuners with a hex head bushing and standard two-screw pattern for easy swap-in.
• Pearloid buttons: The keystone pearloid buttons and pin-stripe detail deliver a vintage look that matches classic instruments.

Who It's For

These tuners are best for electric guitarists who want a straightforward upgrade to improve tuning accuracy and make string changes quicker. Players with instruments that accept 10mm headstock holes and the Kluson-style two-screw mounting pattern will find installation simple and largely bolt-on.

Conversely, builders or owners of exotic headstocks with nonstandard hole sizes or different bushing types should verify fit before buying, and those after ultra-lightweight locking machines for acoustic headstocks may prefer a different design focused on minimal mass.

Pros & Cons

Pros

• Improved tuning stability from the 19:1 gear ratio and sealed housing.
• Locking clamp makes string changes faster and reduces slippage under bending.
• Includes screws and ferrules, so no extra parts are required for standard installs.
• Pearloid keystone buttons keep a vintage aesthetic while modernizing function.

Cons

• Designed for 10mm headstock holes and a specific bushing style, so some guitars may need modification.
• Die-cast housings are heavier than some lightweight alternatives, which could slightly alter headstock balance.
