Setup Guides
The same knowledge that's inside the app — free, plain-language, no fluff.
The Correct Setup Order
Setup is a chain of dependencies — relief before action, action before intonation. Do it in the wrong order and you'll undo your own work. Start here.
How to Fix Fret Buzz
Where the buzz happens tells you what's causing it. Diagnose by symptom — open strings, low frets, middle, upper, or everywhere — and fix it.
Truss Rod & Neck Relief
The capo test, the 0.25mm target, which way to turn — and the one rule that keeps you from an expensive repair.
Action Height
How to measure string height properly, with the actual Fender and Gibson factory specs, and how to adjust saddles and thumbwheels.
Intonation
In tune open but sour up the neck? The 12th-fret method: sharp means saddle back, flat means saddle forward.
All of this, in your pocket
GuitarDoc turns these guides into an interactive workshop: guided steps, animated turn diagrams, a free strobe tuner, a buzz troubleshooter — and Pro measurement tools that replace your gauges, with guided intonation for every string. 100% offline, no subscription.
