Why Professional Guitar Setups Should Be Measured, Not Guessed

-

 Many guitar players hear phrases like:


“I just set it up by feel.”

“I’ve been doing this for years — I don’t need gauges.”


Experience absolutely matters in guitar setup work.

But experience without measurement leads to inconsistency.


When a guitar chokes on bends, buzzes unpredictably, or feels great one day and uncomfortable the next, the cause is often guesswork rather than repeatable measurement.



The Limits of Sight and Feel



Human hands are not precision instruments.


Differences as small as:


  • 0.004–0.006 inches of neck relief
  • 0.1 mm of string height
  • a fraction of a nut slot depth



can dramatically change how a guitar plays.


Two technicians can assess the same neck and arrive at very different results if they rely only on feel.



Why Measured Setups Are More Reliable



A professional setup should be:


  • Measurable
  • Repeatable
  • Transparent



That’s why I use:


  • Imperial neck-relief gauges
  • Feeler gauges for nut slot height
  • Measured string action at the 12th fret
  • Branded nut files matched to string gauge



Instead of “that feels about right,” the guitar is set to known tolerances that can be checked, documented, and refined.



Tools Protect the Player



Accurate tools don’t just protect the guitar — they protect the player.


Measured setups help ensure:


  • smoother bends without choking
  • reduced hand fatigue
  • improved intonation
  • consistent playability across the neck



This is especially important for beginners and anyone struggling with barre chords or finger strain.



Skill Backed by Measurement



Experience still matters — but tools back it up.


They remove guesswork and allow the same high standard to be applied across different instruments, string gauges, and playing styles.

Final Thoughts



A guitar setup shouldn’t depend on who happens to be holding the instrument that day.


It should be:

✔ precise

✔ repeatable

✔ tailored to the player


That’s how guitars stay playable long-term — not just on the bench, but in real-world playing.

The CAGED System: Unlocking the Guitar

-
 The CAGED System: Unlocking the Guitar Neck ## 🔑 What Is the CAGED System? The **CAGED system** is a way of visualizing the guitar fretboard using five basic chord shapes:   **C – A – G – E – D**. These shapes aren’t just open chords—they’re movable frameworks that help you understand **chords**, **scales**, and **arpeggios** across the entire neck. Each shape corresponds to a **position** on the fretboard and connects to a **major scale pattern**, **pentatonic shape**, and **chord voicing**. --- ## 🧠 Why It Matters - **Fretboard Navigation**: CAGED gives you a map of the neck. No more getting lost past the 5th fret. - **Chord Voicings**: You’ll learn how to play the same chord in multiple places with different tonal colours. - **Improvisation**: Link pentatonic shapes to chord tones for melodic soloing. - **Composition**: Build progressions and riffs that move across the neck, not just up and down. --- ## 🧩 The Five Shapes Here’s how the five shapes look as **movable chor...

Why does the neck pick up tarnish quicker than the bridge pick up?

-
  That’s a really good observation — and it’s quite a common one with Les Pauls and other Gibson-style guitars. The neck pickup tends to tarnish faster than the bridge pickup for a few simple but interconnected reasons: 🎸 1.  Proximity to Your Hands and Sweat The neck pickup sits right under where your picking hand rests during playing, especially if you strum near the neck or play rhythm parts. Sweat, skin oils, and moisture from your fingers transfer to the pickup cover. Even tiny amounts of sweat (which is slightly acidic and salty) can corrode nickel or chrome plating over time. By contrast, the bridge pickup is further away and gets less direct exposure. 🌡️ 2.  Temperature and Moisture Differences The neck pickup is closer to the warmth of your body, especially when you’re playing seated or standing with the guitar pressed against your torso. That warmth encourages condensation and oxidation to form more easily on metal parts. ⚙️ 3...

Investing in the Right Tools for Precision Setups

-
Investing in the Right Tools for Precision Guitar Setups One of the most satisfying parts of being a guitarist is keeping your instrument in top playing condition. A guitar that feels smooth, stays in tune, and resonates clearly can make all the difference when you’re practising at home, recording, or performing live. That’s why I’ve recently expanded my toolkit to include a new nut gauge and an updated neck relief gauge — small but powerful tools that help deliver the kind of precise setups every guitar deserves. Why Proper Neck Relief Matters The neck of a guitar naturally has a small amount of curvature, known as relief. Too much relief, and the strings feel high and sluggish; too little, and you’ll end up with fret buzz. A quality neck relief gauge allows me to measure that curvature with accuracy, ensuring your guitar is set right in the sweet spot. This means smoother playability and better overall tone. The Role of a Nut Gauge The guitar nut is often overlooked, but it’s ...
