A broken string means you need to remove the old one and thread a new one through the same slot

When a guitar string breaks, the fix is straightforward: take out the broken piece, insert a new string of the same gauge, and tune it to pitch. The whole job takes about five to ten minutes once you have a replacement string on hand. You do not need special tools—a wire cutter helps but is not required, and your fingers can do most of the work.

The process is the same whether the string snapped at the bridge, the tuning peg, or somewhere in the middle. The broken section stays in the guitar until you remove it; the other section comes out when you loosen the tuning peg. A new string goes in through the bridge hole, up the neck, and around the tuning post, then gets tightened until it reaches the correct pitch.

Key Takeaways

  • Loosen the tuning peg for the broken string all the way down so the tension releases and the string goes slack.
  • Pull the old string out through the bridge hole on the body and unwind it from the tuning post at the headstock.
  • Insert the new string through the bridge hole, thread it up to the headstock, and wrap it around the tuning post in the correct direction.
  • Tighten the tuning peg slowly while keeping tension on the string so it winds evenly and does not slip.
  • Tune the new string to pitch using a tuner, then check it again after a few minutes because new strings settle and go flat.

Loosen and remove the broken string

Turn the tuning peg for the broken string counterclockwise until the string goes completely slack. Turn it all the way—do not stop when the string feels loose. The goal is to remove all tension so the string hangs freely and cannot snap again as you work.

Once the string is slack, pull it out of the bridge hole on the body of the guitar. If the string is still in two pieces, pull out whichever section is still threaded through the bridge. Then go to the headstock and unwind the loose string from the tuning post by hand. If the string is tangled or stuck, a gentle tug while turning the post will free it.

Insert the new string through the bridge

Take your new string—it should be the same gauge as the one that broke—and insert the ball end (the small metal knot at one end) into the bridge hole. Push it all the way through so the string lies flat against the bridge. The ball end sits inside the guitar body and anchors the string; the long end comes out the front and goes up the neck toward the headstock.

If your guitar has a bridge pin (a small wooden or plastic peg that holds the string in place), insert the pin after the string is through the hole. Turn it clockwise until it sits snug. The pin keeps the string from sliding back out. Some guitars, especially acoustic models, use bridge pins; electric guitars usually do not.

Wind the string around the tuning post

Pull the string up the neck toward the headstock, keeping it roughly centered over the fretboard. At the headstock, insert the string through the hole in the tuning post for that string. The hole is small; push the string through until about two to three inches of slack hangs on the other side.

Bend the string at a right angle just above the tuning post, then begin turning the tuning peg clockwise. As you turn, the string wraps around the post in a spiral. Keep light tension on the string with your other hand so it winds neatly and does not overlap itself. The wraps should go downward on the post, away from the headstock edge, so they do not bunch up at the top.

Wind until the string is snug and has no slack, but do not crank it tight yet. You want the string to be under tension but not at full pitch. This prevents the string from slipping as you make the final adjustments.

Tune the string to pitch and let it settle

Use a tuner to bring the string up to the correct pitch. Turn the tuning peg slowly and watch the tuner display. Stop when the tuner shows the string is in tune. New strings go sharp (higher in pitch) as you tighten them, so you may overshoot slightly; if that happens, loosen a quarter turn and retune.

After you finish tuning, wait a few minutes and check the pitch again. New strings stretch as they settle under tension, which causes them to drop in pitch. You may need to retune once or twice over the next hour. This is normal and does not mean anything is wrong. After a day or two of playing, the string will stabilize and hold its pitch much better.

When to call a professional

String replacement is a task almost any player can handle, but a few situations warrant a trip to a repair shop. If the bridge or bridge pin is cracked or damaged, a professional should assess whether it needs replacement before you install a new string. If the tuning post is bent or stripped (the hole is enlarged and the string slips), the post may need to be replaced, which requires tools and informed beyond basic maintenance.

If you are uncomfortable working on your guitar or the string keeps slipping no matter how carefully you wind it, a technician can do the job in a few minutes and check the rest of the instrument at the same time. The cost is usually modest, and the peace of mind is worth it if you are new to the instrument.

Frequently Asked Questions

What gauge string do I need if I do not know what broke?

Look at the other strings on the guitar—they are labeled on the package they came in, or you can check the guitar's manual. Strings come in sets, and each set has a standard gauge for each position. If you have lost the original packaging, a music store can identify the gauge by looking at the remaining strings or by knowing your guitar model.

Can I replace just one string or do I have to replace all six?

You can replace just the broken one. Many players replace strings one at a time as they break. Replacing all six at once is common when you want a fresh sound or when multiple strings are old and dull, but it is not required. A single new string will sound slightly brighter than the older ones until they all age together.

How tight should I wind the string around the tuning post?

Wind it snugly but not so tight that the post becomes hard to turn. You should be able to turn the tuning peg with normal finger pressure. If you have to strain or use a tool to tune, you have wound it too tight. The string should not slip when you play, but the tuning peg should move smoothly.

Why does my new string sound different from the old ones?

New strings are brighter and have more sustain than old ones. Over time, strings lose brightness and become duller. This is normal wear. The new string will sound noticeably different for a few hours or a day, then blend in as the older strings' tone stabilizes. If the difference bothers you, replacing all six strings at once gives you a uniform, bright tone.

What should I do with the broken string?

Broken strings can be recycled if your area has a metal recycling program, since they are made of steel or steel-wrapped nylon. Otherwise, wrap the sharp ends in tape or paper and throw it away. Do not leave broken strings loose where they can cause injury.
