Precision Fret Replacement & Leveling for Peak Playability

The condition of your frets dictates more than just the ease of producing a note; it directly impacts the smoothness of your bends, the stability of your vibrato, and the overall intonation of the guitar. For professional musicians and recording artists, even a slight irregularity in the fret plane can introduce audible noise and mechanical instability that compromises a performance.

Our approach goes beyond simple sanding. We analyze the relationship between the neck relief and the fret crowns to create a customized "plane" optimized for your specific playing style. This allows us to maintain a low action while completely eliminating parasitic fret buzz, resulting in a responsive instrument that feels effortless under the fingers.

Who Should Consider This Service?

If you notice any of the following symptoms, your instrument is likely due for fret maintenance. Ignoring these signs often leads to accelerated string wear and can eventually necessitate a more expensive full refret.

• Notes that "cut out" or produce a clicking sound on specific frets.
• The inability to lower string action without immediately triggering fret buzz.
• A "gritty" or catching sensation during bends and slides.
• Visible flattening of the fret crowns due to years of heavy use.
• Vintage instruments that require a balance between maintaining original character and improving modern playability.

Workflow and Technical Details

Every instrument received at Ketiminetrail is first acclimated within our climate-controlled workshop, where humidity is strictly maintained between 45-55%. Because wood expands and contracts based on the environment, performing precision leveling on an unstable neck would lead to inconsistencies once the instrument returns to your home.

Whenever possible, we prioritize leveling to preserve as much original fret material as possible. However, if the wear is too severe—meaning leveling would leave the frets too low to maintain a viable string height—we will recommend a full refret. During a replacement, you can choose from various materials, including traditional nickel-silver or durable stainless steel, depending on your longevity requirements.

Client Preparation

To ensure the result matches your expectations, please provide the following information when booking your appointment:

• Specific pain points (e.g., "the note dies at the 12th fret on the G string").
• Preferred action height (specific measurements or a general preference like "as low as possible").
• The gauge of strings you typically use.
• Your primary playing style (e.g., heavy shredding, jazz chords, or delicate fingerstyle).

What You Receive Upon Delivery

Upon completion of the service, we provide a comprehensive hand-over package:

• Your fully optimized instrument.
• A detailed work report specifying the leveling range or the specific frets replaced.
• Measurement data regarding the final string height and neck relief.
• Professional advice on daily maintenance to extend the lifespan of your frets.

Turnaround and Timelines

Standard fret leveling typically requires 7 to 14 days. Full refretting takes longer, as it involves deep cleaning of the fretboard, end-dressing the new wire, and allowing the wood to settle after the slots are processed.

While we accept requests for urgent turnarounds, we prioritize quality. Precision leveling requires the wood to be completely stable, and we will not rush this process at the expense of the instrument's long-term health.

Exclusions and Additional Costs

This specific service focuses on fret height and replacement. The following items are not included and will be quoted separately:

• Filling deep gouges or repairing structural cracks in the fretboard.
• Complete replacement of the nut (though basic slot adjustment is included).
• Electrical repairs, pot replacements, or pickup swaps.
• Replacement with endangered materials (e.g., Brazilian Rosewood) without valid CITES documentation.

Pricing Logic and Consumption Tax

Pricing is determined by the scope of work—whether it is a partial leveling or a full replacement—and the complexity of the instrument. All prices are listed in accordance with Japanese law, showing the base price (税抜) and the final price including the 10% Consumption Tax (税込).

Following a free initial diagnostic, we provide a formal estimate. Work only begins after your explicit consent, ensuring there are no hidden fees or unexpected charges upon collection.

Service Checklist

• Comprehensive fret height mapping and measurement.
• Precision leveling for a perfectly flat plane.
• Professional crowning of each fret.
• High-grit mirror polishing.
• Light cleaning of the fretboard surface.
• Action reset and octave intonation adjustment.
• Final buzz-check and playability verification.

Optimizing your frets is not merely a repair; it is a refinement of your instrument's interface. When the physical barrier between your fingers and the strings is perfected, your expressive range expands.
