A clip-on tuner is the quickest route. Pluck one string at a time, let the note settle, and turn the peg until the needle centres. Tune up to pitch rather than down — it holds better.

Without a tuner, take the low E from a piano or a reference tone and tune the rest by comparing adjacent strings at the fifth fret: fifth fret of E is A, of A is D, of D is G, and the fourth fret of G is B. The high E matches the fifth fret of B.

Change one string at a time so the neck never loses all its tension at once. Loosen the old string, pull the pin if your bridge uses one, and thread the new string through.

Leave enough slack for two or three turns around the post, then wind downwards so the string sits neatly. Once it is up to pitch, stretch it gently with a few firm pulls and retune — new strings settle far faster that way.

Wipe the strings and fretboard with a dry cloth after playing. Oils from your hands are what kill strings, not playing time.

Keep the guitar between roughly 45 and 55 percent humidity. Dry air shrinks the wood and raises the action; damp air swells it. A hard case and a simple humidity pack go a long way.

If the action feels high or the strings buzz, the neck relief may need a small truss rod adjustment. That is a job worth having a shop do the first time.
