Changing acoustic guitar strings takes about 15 to 20 minutes once you know the steps
You will need wire cutters, a string winder (optional but speeds the job), new acoustic strings, and a tuner. Remove the old strings one at a time by loosening the tuning pegs at the headstock until the string goes slack, then unwind it completely. Pull the bridge pins — the small pegs holding the strings in the bridge — straight up and out. The old string will come free. Repeat for all six strings, or change them one at a time if you want to keep tension on the neck.
Insert the new string into the bridge hole, replace the bridge pin, and thread the string up to the headstock. Wind it around the tuning peg post two or three times, then turn the peg to tighten. The string should wrap downward on the post, not upward. Tune to pitch with a tuner, then repeat for the remaining five strings. New strings take a few hours to settle and will go flat — retune them several times over the first day.
Key Takeaways
- Loosen each string at the tuning peg, remove the bridge pin from the bridge, and pull the old string free before installing the new one.
- Thread the new string into the bridge hole, replace the bridge pin, and wind the string around the tuning peg post two or three times before tightening.
- New strings will drift flat for several hours after installation, so retune them multiple times on the first day.
- A string winder saves time but is not required — you can wind by hand in about the same time as it takes to change all six strings.
- Changing strings one at a time keeps neck tension steady and is easier than removing all six at once, especially if you are new to the task.
Why you should loosen strings before pulling the bridge pins
The bridge pins sit under string tension. If you try to pull them without loosening the strings first, you risk cracking the bridge or stripping the pin holes. Always loosen the tuning pegs until the string is completely slack before you touch the bridge.
Loosening also makes the job safer for your hands. A tight string can snap suddenly and cut your fingers if you are working near the bridge. Slack strings are forgiving and let you work at your own pace.
How to wind the string onto the tuning peg correctly
Thread the string through the hole in the tuning peg post. Leave about two inches of slack between the bridge and the post — this gives you room to wrap the string around the post without it slipping. Hold the string taut with one hand and turn the tuning peg with the other.
The string should wrap downward on the post, moving away from the center of the headstock with each turn. If it wraps upward or crosses itself, the string will slip and go out of tune. Two or three wraps is enough — more than that makes tuning harder and wastes string. Once the string is wound, tune it to pitch with a tuner.
What to do if a string breaks during installation
If a new string breaks while you are winding it, cut off the damaged section with wire cutters and start over with the remaining length. Most acoustic string packs include six full-length strings, so you have one spare if needed.
If you break a string after it is fully installed and tuned, you will need a replacement. Keep a spare set on hand so you can change a broken string without stopping practice or a performance. A broken string usually means the tuning peg was wound too tightly or the string was old and brittle — new strings are less likely to snap.
Bridge pins: what they are and how to replace them
Bridge pins are small pegs, usually made of plastic or bone, that hold the strings in place at the bridge. They sit in holes drilled into the bridge and press down on the string to keep it from sliding out. When you remove a string, the pin comes out with it.
When you install a new string, insert it into the bridge hole first, then push the bridge pin straight down into the hole. The pin should sit flush with the bridge surface or slightly recessed. If a pin is cracked or stripped, replace it with a new one from a spare set — most guitar shops sell bridge pin replacements for a few dollars.
How long new strings take to settle and stay in tune
New acoustic strings are stretchy and will go flat within the first few hours of playing. Retune them after 15 minutes of playing, again after an hour, and once more before you play seriously. This stretching is normal and does not mean the strings are defective.
After the first day, new strings stabilize and hold tune much better. By the end of a week, they will be fully settled. If a string continues to go flat after several days, check that the bridge pin is seated properly and that the tuning peg is not slipping — both are common causes of tuning drift.
When to change strings and how often they last
Acoustic strings typically last two to four months with regular playing, longer if you play casually. Change them when they sound dull, feel rough under your fingers, or when you notice rust or discoloration on the wound strings. Broken strings are an obvious sign, but strings that have straightforward lost brightness are worth replacing too.
If you play daily, change strings every two months. If you play a few times a week, four months is reasonable. Strings that sit unused do not degrade as quickly, but they still lose tone over time. If your guitar has been in a case for months, new strings will make a noticeable difference in sound.
Frequently Asked Questions
Should I change all six strings at once or one at a time?
Changing one at a time keeps tension on the neck and is easier for beginners. Removing all six at once lets you clean the fretboard and bridge, but requires more care when reinstalling. Either method works — choose based on whether you want to clean the guitar at the same time.
What is the correct string order from thickest to thinnest?
Acoustic strings come in a set labeled by gauge. The order from thickest to thinnest is E, A, D, G, B, E. Most string packs are labeled, so you can match the number on the package to the string position. If you are unsure, the thickest string always goes in the hole closest to the tuning peg marked E on the headstock.
Do I need a string winder?
A string winder speeds up the winding process but is not required. You can wind strings by hand in about the same time it takes to change all six. A winder costs five to ten dollars and is useful if you change strings frequently, but it is not essential for the task.
Why do new strings sound different from old ones?
New strings are brighter and have more sustain because the metal is not yet oxidized or worn. Old strings lose brightness as the windings flatten and the metal tarnishes. This is why replacing dull-sounding strings with new ones makes such a noticeable difference in tone.
Can I reuse old strings?
Old strings can be cleaned and reused for a short time, but they will not sound as good as new ones and may break more easily. If you are traveling or in a pinch, reusing is possible — just clean them with a soft cloth first. For regular playing, new strings are worth the cost.
