The Hipshot 6GLO Grip-Lock tuning machines offer a secure grip on strings, minimizing tuning slippage and enhancing playing accuracy, with the only caveat being their specific fit for 3+3 headstock configurations. These tuning machines feature a high 18:1 gear ratio for fine adjustments and a patented Grip-Lock mechanism to hold strings firmly in place.

These specific 6GLO models are designed for a standard 3+3 configuration, which can be found on both right-handed and left-handed guitars. Ensure your left-handed guitar has the correct 3+3 layout.
The gear ratio is 18:1. A higher gear ratio like 18:1 allows for finer, more precise adjustments when tuning, making it easier to hit and maintain exact pitches compared to lower ratios found on standard tuners.
The Grip-Lock system utilizes a small set screw within the tuning post that, when tightened, firmly secures the string end, preventing it from slipping under tension.
While technically possible, it is not recommended for optimal performance and aesthetics. These tuners are designed to work as a set for consistent tuning stability across all strings.
Basic guitar tools like screwdrivers are usually sufficient. However, depending on your guitar, you might need a socket wrench or Allen keys for mounting screws and the set screw. Refer to installation guides for specifics.
Minimal maintenance is required. Keep them clean with a soft cloth and ensure the set screw is snug. No lubrication is typically needed unless specified by the manufacturer for specific environmental conditions.
Ensure the Grip-Lock set screw is properly tightened on each string. Verify that the string is seated correctly within the post. Check that the tuning machine mounting screws are secure.
Check for any obstructions. Ensure the tuning machine is correctly aligned and securely mounted. If stiffness persists, contact Hipshot support.
Confirm the headstock configuration matches the 3+3 design. If hole sizes differ, professional modification or the use of adapter bushings may be required. Consult a guitar technician if unsure.
Compatibility: These tuning machines are designed exclusively for guitars featuring a 3+3 headstock configuration. Ensure your guitar's headstock has three tuning posts on each side before purchasing. Verify post diameter and screw hole spacing if replacing existing tuners.
Setup:
Care: Clean the tuning machines with a dry or slightly damp cloth. Avoid using abrasive cleaners or solvents, which can damage the finish. Periodically check mounting screws and the Grip-Lock set screw for tightness.
