Setup & care

Setup & Care

A guitar is wood, wire, and glue — small habits keep it sounding right for decades.

After every play

Every few weeks

Storage & humidity

Buy a hygrometer

A hygrometer measures the humidity of the air. A small digital one costs about the price of a set of strings, and it is the cheapest insurance a wooden guitar can have — it tells you about a problem weeks before the guitar does.

Solid-wood acoustics are the ones that really care. Laminate bodies and solid-body electrics are far more tolerant, though necks and fretboards move on any guitar.

What a setup does

A setup is a handful of small adjustments that decide how a guitar feels under your hands. Most instruments leave the factory adjusted for shipping, not for playing, and a good setup is the single biggest improvement you can make to a cheap guitar.

Intonation is whether the guitar stays in tune with itself as you move up the neck. Open chords sound fine, then something up at the 7th or 9th fret rings sour — that is intonation, not your tuning.

On an electric each saddle moves individually, so intonation is adjustable at home with a screwdriver and a tuner. On an acoustic the saddle is a single piece and correcting it means shaping or replacing it — that one is a job for a tech.

When to see a tech

Plenty of maintenance is yours to do. These are the jobs worth paying someone for — a full setup costs less than you would think, and it transforms a guitar.

Wipe down the strings and body with a dry cloth after playing.

Store the guitar in its case or on a stand, away from direct sun or heat.

Wash your hands before playing to reduce grime on the strings and fretboard.

Wipe down the fretboard and check for built-up grime.

Condition an unfinished fretboard every few months with a light oil.

Check tuning stability and listen for buzzing or dead frets.

Inspect strings for corrosion or dullness — replace when tone flattens out.

Aim for 45–55% relative humidity around the guitar.

Use a case humidifier in dry seasons to prevent cracking.

Avoid cars, attics, and direct sun — heat warps wood and finish.

For long-term storage, loosen strings slightly rather than fully.

Aim for 45 to 55 percent

That is the range most guitars are built in and happiest living in. Anywhere from 40 to 60 is fine day to day.

Too dry is the dangerous one

Below about 35 percent the top sinks, the action drops, fret ends turn sharp and the wood can crack. Winter heating is the usual culprit.

Too damp swells it

Above about 65 percent the top rises, the action climbs and the tone goes dull and muddy. Damp rooms and lofts do this.

Measure where the guitar lives

Put the hygrometer in the case or on the wall beside the stand, not in another room. Give it a couple of hours to settle before you trust the reading.

Act on what it tells you

A soundhole humidifier or a case humidifier packet costs very little and fixes a dry room. A dehumidifier or silica packs handle the opposite.

Tech or careful DIY

The truss rod sets a very slight forward bow in the neck. Too little and the strings buzz; too much and the action is high in the middle of the neck. Small turns only, and let the neck settle between them.

Action height

How far the strings sit above the frets, set at the bridge or saddle. Lower is easier to play but buzzes sooner — the right height depends on how hard you play.

Slots cut too high make the first few frets feel stiff and play sharp. This is the most commonly neglected part of a cheap guitar and the most transformative to fix. Cut too deep and the nut needs replacing, so leave it to someone with the files.

Pickup height

On an electric, two screws either side of each pickup. Closer to the strings is louder, but too close pulls the strings out of tune magnetically, especially on the bass side.

DIY on electric, tech on acoustic

Setting each string so it plays in tune all the way up the neck. See below.

Fit fresh strings and tune the guitar accurately. Old strings will never intonate properly.

Play the open string, then the note at the 12th fret, and compare the two on a tuner.

If the 12th-fret note reads sharp, the string is too short — move that saddle back, away from the neck. If it reads flat, move the saddle forward.

Retune and check again after every adjustment, and work one string at a time. Small movements make a surprising difference.

A full setup on a new guitar, or once a year on one you play often. It is the best money you will spend on the instrument.

Anything involving the nut — slot depth, a replacement, or a string that keeps pinging out of tune.

Fret work: buzzing that persists after a setup, flat spots, or sharp ends along the neck edge.

A truss rod that feels tight, will not move, or makes any cracking sound. Stop immediately and take it in.

Acoustic intonation, a lifting bridge, or a crack in the top.

Electrics with crackling controls, a dead pickup, or an output jack that has worked loose.
