What to check first
A practical sequence is: install/settle strings and tune to pitch; establish neck relief; set action; evaluate nut action; set pickup height where applicable; then set intonation and perform a final play test.
What the result tells you
Measure, adjust one thing, retune, and check again. The goal is not to touch every adjustment. The goal is to leave correct things alone.
Write down the current measurement before changing anything.
Small, reversible adjustments are easier to understand and undo.
Stuck, stripped, lifted or structural parts are not routine setup territory.
Bench questions
Do I need to chase a factory number exactly?
No. Factory specs are useful baselines, but playing attack, string gauge, fret condition, radius and preference affect the setup that actually works.
Should I change more than one thing at once?
No. Make one measured change, retune, and test again so you know what caused the result.
When should I stop?
Stop if an adjustment is stuck, requires unusual force, hardware is stripped, a fret is visibly lifting, or the problem looks structural rather than setup-related.

Where to go next
If this check does not explain the symptom, don’t compensate by randomly changing another adjustment. Go back through the symptom diagnostician and follow the next branch.
