You can change guitar strings yourself in about 15 to 20 minutes with just a few basic tools

Changing guitar strings is one of the most common maintenance tasks you will do as a player, and it requires no special skill—just a wire cutter, a string winder (optional but helpful), and a new set of strings that match your guitar type. The process is the same whether you play acoustic or electric: loosen the tuning pegs, remove the old strings, clean the fretboard while it is exposed, thread the new strings through the bridge or bridge pins, and wind them back up to pitch.

Most players change strings every three to six months depending on how often they play, though strings that sound dull, feel rough, or have visible rust spots need replacing sooner. The entire job becomes faster with practice—your first time may take 30 minutes, but after a few changes you will work through it in 15.

Key Takeaways

  • You need wire cutters, a string winder (optional), new strings matched to your guitar type, and a tuner to bring the strings back to pitch.
  • Loosen all six tuning pegs until the strings go slack, then remove them one at a time or all together depending on how much cleaning you want to do.
  • Thread each new string through the bridge or under the bridge pins, then wind it around the tuning peg post in a downward spiral until it reaches pitch.
  • New strings take 24 to 48 hours to fully settle and hold pitch, so expect to retune several times in the first day.

Gather your tools and materials before you start

You will need a new set of strings—acoustic strings for an acoustic guitar, electric strings for an electric guitar, and classical nylon strings for a classical guitar. The package will say which guitar type it fits. You will also need wire cutters to trim the excess string after winding, a tuner (a clip-on tuner costs $10 to $20 and works on any guitar), and a string winder, which is a small hand-crank tool that speeds up the winding process. A string winder is not essential, but it saves your hand from cramping and makes the job faster.

Have a damp cloth ready to wipe down the fretboard once the strings are off—this is the only time you can easily reach the wood under the strings. If your guitar has a rosewood or ebony fretboard, you can use lemon oil or fretboard conditioner after wiping, though this is optional. Keep the old strings nearby until you finish, in case you need to check how they were wound or threaded. A flathead screwdriver or the notch on a string winder will help you remove bridge pins on acoustic guitars.

Remove the old strings

Loosen all six tuning pegs by turning them counterclockwise (the direction varies slightly by headstock design, but turning away from the center of the headstock is the safe bet). Turn slowly and listen—you will hear the pitch drop as the tension releases. Keep turning until all strings are slack enough that you can lift them away from the fretboard without resistance.

You can now remove the strings one at a time or all at once. Removing them all at once lets you clean the entire fretboard and under the bridge, but it also means the neck loses tension all at once, which is fine for a few minutes. If you prefer to keep some tension on the neck, remove and replace strings one at a time—this takes longer but is gentler on older guitars. For most players, removing all six at once is simpler and faster.

On an acoustic guitar, remove the bridge pins (the small pegs that hold the strings in the bridge holes) by gently prying them up with a flathead screwdriver or the notch on a string winder. On an electric guitar, the strings thread through the bridge or bridge block, so straightforward pull them out. Coil the old strings and set them aside.

Clean the fretboard while it is exposed

With the strings off, you have clear access to the fretboard for the first time in months. Wipe it down with a slightly damp cloth to remove dust and dried sweat. Do not soak the wood—just dampen the cloth enough that it leaves a wet trail but does not drip. Wipe along the length of each fret and the spaces between them.

If the fretboard looks dry or dull, you can explore fretboard conditioner or lemon oil after it dries. This step is optional and not necessary every time you change strings, but doing it once or twice a year keeps the wood from cracking. Let the fretboard dry completely before threading the new strings—usually five to ten minutes is enough. This is also a good time to wipe down the body and headstock if you want to give the whole guitar a quick cleaning.

Thread the new strings through the bridge

Start with the thickest string (the low E string). On an acoustic guitar, insert the ball end of the string into the bridge hole and replace the bridge pin, pushing it down firmly until it seats. The pin should sit flush with the bridge—if it sticks up, tap it gently with a hammer or the handle of a screwdriver. On an electric guitar, thread the string through the bridge block or bridge hole depending on your model, then pull it up toward the headstock.

On a classical guitar, tie the string to the bridge using a specific knot (the bridge tie knot), which takes a bit of practice but holds reliably once you learn it. Look up a video demonstration if this is your first time—the knot is easier to see than to describe in text. Repeat this process for all six strings, working from thickest to thinnest. This order is not essential, but it helps you keep track of where you are in the process.

Wind the strings onto the tuning pegs

Pull the first string up to the headstock and thread it through the post hole on the corresponding tuning peg. Leave about two inches of slack—this gives you enough string to wrap around the post without running out. Bend the string at a right angle where it exits the post hole.

Turn the tuning peg so the post rotates downward and away from the center of the headstock. As you turn, the string will wrap around the post in a spiral. Keep tension on the string with your other hand so the wraps stay neat and do not overlap. A string winder makes this easier—insert the post into the winder's socket and crank the handle, which turns the peg for you while you hold the string taut.

Wind until the string reaches approximately the correct pitch (your tuner will tell you when to stop). The string should wrap around the post three to four times—more wraps mean slower tuning response, and fewer wraps can cause the string to slip. Once you reach pitch, trim the excess string with wire cutters, leaving about a quarter-inch of slack so the end does not unwind. Repeat for all six strings. This is the most time-consuming part of the process, but it becomes faster with practice.

Tune to pitch and let the strings settle

Use your tuner to bring each string to its correct pitch. Start with the low E string and work your way up to the high E. Tune slightly flat at first, then bring each string up to pitch—this helps the string settle evenly around the post. If a string goes sharp (too high), loosen it slightly and retune rather than trying to bring it back down from above.

New strings will not hold pitch for the first 24 to 48 hours. They will drift flat as the windings settle and the string stretches. Retune every few hours on the first day, and again the next morning. After 24 hours, the strings should hold pitch much more reliably. This is normal and not a sign that anything is wrong. If a string keeps slipping or going flat much faster than the others, check that the bridge pin (on acoustic) is seated firmly or that the string is wound neatly around the post with no overlaps. A loose bridge pin or a sloppy wind can cause tuning instability.

Frequently Asked Questions

How do I know which string gauge to buy?

Check your guitar's manual or the headstock—many guitars have the gauge printed there. If not, look at the package your old strings came in, or measure the thickest string with a caliper. Common gauges are .046 to .010 for electric and .012 to .054 for acoustic. When in doubt, ask at a music store with your guitar model.

Can I change one string at a time without removing the others?

Yes. Loosen one tuning peg, remove the string, thread the new one through, and wind it back up. This takes longer but keeps constant tension on the neck. Many players do this on older guitars or when they break a single string mid-session.

Why do my new strings sound different from the old ones?

New strings are brighter and have more sustain because the windings are clean and the metal has not oxidized yet. They will mellow slightly over a few weeks as you play. This is normal and not a defect.

What should I do with the old strings?

Most music stores will recycle old strings if you bring them in. You can also throw them in the trash, though recycling is better for the environment. Do not flush them down a drain.

Do I need to stretch new strings?

Gently pulling each string away from the fretboard after winding can help it settle faster, but it is not required. If you do stretch them, be gentle—you are not trying to change the pitch, just help the windings seat evenly.
