Properly setting up and maintaining a guitar is crucial for achieving optimal playability, tone, and longevity. To accomplish this, having the right luthier tools is essential. In this article, we will explore the essential tools required for guitar setup and maintenance. Whether you are a seasoned luthier or a guitar enthusiast who enjoys taking care of your instrument, these tools will help you achieve the best possible performance and ensure your guitar stays in pristine condition.


Screwdrivers are a fundamental tool for guitar setup and maintenance. They come in various sizes and types, including flathead and Phillips head, and are used to adjust screws on components such as tuners, pickguards, control plates, and more. Having a set of screwdrivers ensures you have the right tool for the job and enables you to make precise adjustments without damaging the guitar's hardware.

Hex Wrenches (Allen Keys)

Hex wrenches, commonly known as Allen keys, are indispensable for adjusting components that use hexagonal socket screws, such as truss rods, bridge saddles, and some types of tuners. These wrenches come in different sizes, and it's crucial to have a set that matches the specific hex screw sizes on your guitar. Properly adjusting these components with hex wrenches ensures proper intonation, action, and neck relief.

Feeler Gauges

Feeler gauges are thin strips of metal used to measure small gaps and clearances. In guitar setup, they are primarily used for setting the string action (height) and adjusting the neck relief. By sliding the appropriate gauge under the strings or on the fretboard, you can achieve precise measurements, ensuring consistent playability across the fretboard.

Ruler/Measuring Tools

Accurate measurements are vital in guitar setup and maintenance. A ruler or measuring tool with both metric and imperial scales allows you to measure string height, neck relief, string spacing, and other critical dimensions. Having a reliable measuring tool helps you achieve precise and consistent setup adjustments.

Nut Files

Nut files are specialized tools used for shaping and adjusting the slots in the guitar nut. They come in various widths corresponding to different string gauges, ensuring proper string action and preventing string binding or buzzing. Proper nut slotting is crucial for maintaining accurate intonation and smooth playability.

Fret Crowning Files

After leveling the frets, the tops of the frets need to be reshaped and rounded off for optimal playability. Fret crowning files are specifically designed for this task. They allow you to precisely shape the frets, eliminating any flat spots or sharp edges that can cause discomfort while playing.

Fret Rockers

Fret rockers are simple yet invaluable tools for identifying uneven or high frets. These tools consist of straight edges with different lengths, allowing you to detect any areas where the frets may require leveling. By rocking the tool along the fretboard, you can pinpoint and address any high spots that may cause buzzing or intonation issues.

String Action Gauges

String action gauges help measure the height of the strings above the fretboard. They are essential for achieving proper string action, ensuring a comfortable playing experience without excessive buzzing or string tension. String action gauges typically feature multiple measurements, allowing you to set the desired string height at different positions along the fretboard.

Nut Slotting Files

Nut slotting files are used to adjust the depth and width of the slots in the guitar nut. They ensure proper string spacing and clearance, contributing to accurate intonation and smooth performance. Nut slotting files come in various sizes to accommodate different string gauges and allow for precise nut adjustments.

Fret Tang Nippers

During fret replacement or repair, fret tang nippers are indispensable tools for trimming the tangs on the ends of the fret wires. They ensure a clean and flush fit when inserting new frets or replacing damaged ones. Properly trimmed fret tangs result in secure and stable fret installation, enhancing overall playability and longevity.


Having the essential luthier tools for guitar setup and maintenance is crucial for achieving optimal playability, tone, and longevity of your instrument. From screwdrivers and hex wrenches to nut files and fret crowning files, each tool serves a specific purpose in the setup and maintenance process. By investing in these tools and learning how to use them effectively, you can confidently perform adjustments, repairs, and maintenance tasks, ensuring your guitar is always in its best possible condition and ready to deliver exceptional musical experiences.
