GUITAR SETUP GUY / DIAGNOSTIC WORKSTATION
A setup website that starts with the guitar, not an article

Put the guitar on the bench.

Tell Guitar Setup Guy what you’re working on, what it’s doing, and where the problem lives. The site keeps the guitar profile in your browser and builds the next sensible check around the actual symptom.

The Diagnostician

Start where the problem actually lives.

You can answer in plain English, or jump straight to a fret-zone map if the problem is obvious under your fingers.

Why I’m pointing there

Don’t adjust anything yet.

Can I keep playing it?

Quick relief checker

If you already measured the gap around fret 7–8, enter it in inches.

The Workstation

Build the procedure around this guitar.

This is the part that makes the site different. You are not following one universal checklist. The bench procedure changes based on the symptom and where it happens.

Bench rule: if an adjustment is stuck, damaged, visibly structural, or requires force, the procedure ends there.
My Guitar

Tell me about the patient.

Save the basics once and future tools can use them. This stays in your browser. No account, no newsletter ambush.

The setup logic

Every adjustment has a job.

The trick is knowing which job you’re solving. A truss rod is not an action knob. Intonation is not the first thing you set. Nut work is not something to “try.”

01 / GEOMETRY

Relief

Controls the neck’s longitudinal curve and string clearance through the middle of the neck.

Check relief →
02 / HEIGHT

Action + Nut

Controls how high the strings sit, but nut height matters most near the first few frets.

Check action →
03 / SCALE

Intonation

Fine-tunes effective string length after the rest of the setup is stable.

Check intonation →
What you actually need

A tiny bench kit beats a giant toolbox.

For diagnosis and basic setup measurements, a good tuner, a capo, feeler gauges and an action gauge or accurate ruler get you surprisingly far.

STOP CONDITIONS: stuck truss rod, visibly lifting fret, cracked or lifting acoustic bridge, structural movement, stripped hardware, or anything that requires force to “make it go.”

Bench checkpoint

Don’t lose track of what you changed.

Green, yellow and stop risk scale

GREEN Normal measurement or reversible setup territory.

YELLOW Proceed only if you understand the adjustment and have a real measurement.

STOP Structural issue, stuck hardware, excessive force, stripped parts, lifted frets or bridge problems.
