How to Check Your Guitar’s Setup at Home

You do not need a bench full of tools to get a decent read on how your guitar is doing. Most of what we check when an instrument comes into the shop, you can check at home with your eyes, your ears and your hands. Here is how to run through it, and how to know when something needs a professional.

Start with a look over

Give the whole guitar a once-over. Any scratches, dings or dents you were not aware of? Some need attention. Plenty are just beauty marks, and I am a fan of beauty marks, so often you can leave them well alone.

How does it feel to play?

Your hands usually know before your eyes do. If the guitar has become physically harder or less comfortable to play than it used to be, chances are the neck has bowed and the action has crept up. If you are getting dead notes, or notes that fret out when you bend, chances are the string height has dropped. Either way, the guitar is telling you it wants a setup.

Check the neck relief with the string

Your string makes a perfectly good straight edge. Fret it at the first fret and up where the neck meets the body, which takes the nut and the saddle out of the equation, then give the string a tap around the seventh fret. A small click means a small amount of relief, which is pretty much where you want it. Too much relief and the middle of the neck gets sloppy, with the action high in the middle even when it is low at both ends. If you need to raise the action, it is usually done in combination with raising the saddle rather than just cranking in relief.

Feel the fret ends

Run your hand along the edges of the neck. If the fret ends feel sharp, the neck has dried out and shrunk back from the frets. That is typical in a Canadian winter, and it is also common on newer guitars that were built in a humid climate and then landed here. People sometimes think a humidifier alone will fix it, and it can help, but chasing an endless battle with humidity is a challenge. Usually you just get the fret ends filed and the problem is gone.

Look at the frets themselves

Check for pits and grooves. Aggressive players wear divots into the frets, and here is the sneaky part: if there is a groove in the third fret and you press a note there, it can still buzz against the fourth even when the frets are technically level. Flat frets matter too. Nickel frets are soft, and once the crowns wear flat there is more metal under the string than there needs to be, which makes bends feel slow and laborious. A proper re-crown brings each fret back to a clean arc, and it is one of those things people do not recognise as a problem until it is fixed, and then they cannot believe how much easier the guitar is to bend on.

The nut

Look at the nut slots. Too low and you get buzz on the open strings. Too high and the first few frets feel stiff and play sharp. There is give and take here for playing style too. A jazz player with a light touch can get away with a very low action, while someone who digs in needs a bit more height. That is not a guitar issue so much as an approach issue, and a setup can be tailored to either.

The truss rod

The truss rod needs to move both ways: tighten to take relief out, loosen to let relief in. If the neck is back bowed, meaning it drops away past around the fifth fret, the question is whether loosening the rod brings relief back. Sometimes a rod is maxed out in one direction, and then the options narrow. A slightly heavier string gauge adds tension and can pull a back bowed neck straight. Raising the nut and saddle can rescue the open position, but the geometry means the saddle would need to be extremely high to fix a back bow, and you save the first few frets at the expense of the rest of the guitar. Maxed out truss rods are a bigger job with a different approach, and that is one to bring in.

Plug in and play everything

Finally, play every note on the neck, and bend everywhere you would normally bend. You are listening for what comes through and what does not. Where you want the action is a set of trade-offs: raise it and you gain sustain but it is more work to play, and too high hurts intonation. Set it very low and it plays like butter, but understand that a dry night can take out the little relief the neck had, and the guitar goes from playing amazingly to buzzing by morning. Players who like their action really low just need more adjustments, more often.

When to bring it in

This home check tells you what is going on. Fixing it is a different skill, and the truss rod, the nut and the frets are the places where an enthusiastic afternoon can create expensive problems. If your check turns something up, that is exactly what our setup assessment is for, and you will know what it needs before any work happens.

Common questions

How often should I check my guitar over?

A quick feel and listen every time you play, and a proper look over when the seasons change. Calgary’s swings from dry to humid move necks more than most places, so spring and fall are the times things shift.

My fret ends are sharp. Is my guitar ruined?

Not at all. The neck has dried out and shrunk a touch, which is normal here. Filing the fret ends sorts it, and a case humidifier over winter helps slow it down.

Should I adjust the truss rod myself?

Small, careful adjustments are learnable, and some players get comfortable with them. But if the rod feels tight, does nothing, or you are not sure which way to go, stop and bring it in. A snapped truss rod turns a setup into a major repair.

What is the ideal action height?

The one that suits your hands and your style. Light-touch players can run lower action than heavy hitters, and there is no single right number. That is why we ask how and what you play before we set a guitar up.

Found something in your check that does not seem right?

Bring your instrument into the shop during opening hours, no appointment needed. Assessments are free and we can usually do them while you’re here, so you leave knowing exactly what it needs. Hours and directions are on the contact page.
