You can change acoustic guitar strings yourself in about 15 to 20 minutes once you know the process

Changing acoustic guitar strings is a straightforward task that does not require special tools beyond what most players already have: wire cutters, a string winder (optional but helpful), and a tuner. The job involves removing the old strings one at a time, cleaning the fretboard while it is exposed, inserting new strings through the bridge pins, and tuning back to pitch. New strings take a few hours to settle and stay in tune, so expect to retune several times in the first day.

Most players change strings every three to six months depending on how often they play and how they sound. Dull, lifeless strings or visible corrosion are signs it is time. Acoustic strings come in different gauges (thicknesses)—light, medium, and heavy—and the gauge you choose affects both tone and how hard the strings are to press down. If you are unsure which gauge your guitar came with, check the original packaging or the manufacturer's website.

Key Takeaways

  • Remove strings one at a time by loosening the tuning pegs, then pull the string out of the bridge pin hole and unwind it from the headstock.
  • Clean the fretboard and body while strings are off, since you cannot reach those areas easily when strings are on.
  • Insert new strings through the bridge pin holes from the top, pull them tight, and find them by pushing the bridge pins down firmly.
  • Wind strings around the tuning pegs in a neat spiral, keeping tension on the string so it wraps evenly and does not slip.
  • New strings will go flat quickly at first, so tune up, play for a few minutes, and retune several times over the first few hours.

What you need before you start

Gather a new set of acoustic guitar strings in the gauge you want, wire cutters, and a tuner (a clip-on tuner is easiest). A string winder speeds up the process but is not required—you can wind strings by hand. Have a soft cloth nearby for cleaning the fretboard and body while the strings are off.

Lay your guitar on a flat surface or hold it in your lap so both hands are free. Work in good light so you can see the bridge pins and tuning pegs clearly. If you are changing strings for the first time, set aside 30 minutes so you are not rushed.

Loosen and remove the old strings

Turn the tuning pegs on the headstock counterclockwise to loosen each string. Loosen all six strings until they are slack enough to pull out easily—you do not have to unwind them completely. Once a string is loose, locate the bridge pin (a small wooden or plastic peg) at the bridge end of the guitar, directly above where the string enters the body. Pull the bridge pin straight up and out.

Pull the string out of the bridge pin hole and continue unwinding it from the tuning peg. Remove all six strings. This is the best time to clean your fretboard and the body of the guitar with a soft, slightly damp cloth. Wipe away dust and any buildup that accumulated under the strings.

Insert the new strings at the bridge

Take the first new string (usually the thickest one, the low E string) and insert the ball end (the small knot at one end) into the bridge pin hole. Push it in firmly so the ball end sits inside the hole and cannot slip back out. The string should stick up out of the hole.

Place the bridge pin back into the hole on top of the string, pushing it down until it sits snug and the string is held in place. The pin should be flush with the bridge surface or just slightly recessed. Repeat this process for all six strings, working from the thickest to the thinnest. Pull each string up and away from the guitar as you insert it so there is tension on it—this keeps the ball end seated properly.

Wind strings onto the tuning pegs

Pull the first string up toward the headstock and insert the other end (the one without the ball) through the hole in the first tuning peg. Leave about two to three inches of slack so you have room to wind. Hold the string taut with one hand and turn the tuning peg counterclockwise with the other hand (or use a string winder if you have one). The string should wrap around the peg post in a neat downward spiral, with each wrap sitting below the one before it.

Keep tension on the string as you wind so the wraps stay tight and do not overlap or slip. Wind until the string is snug but not yet at full pitch—you will tune it up in the next step. Repeat for all six strings, working from the thickest to the thinnest. The thicker strings usually need two to three wraps around the peg; the thinner strings may need three to four wraps to stay in tune.

Tune the strings to pitch

Use your tuner to bring each string up to its correct pitch. Start with the low E string and work toward the high E string. Tune slowly and carefully—new strings stretch as you bring them up to pitch, so you may need to retune each string two or three times before it holds steady. Do not crank the tuning pegs too fast or you risk breaking a new string.

Once all six strings are at pitch, play the guitar for a few minutes. The strings will go flat as they settle, so retune again. Repeat this cycle—play, retune, play—for the next hour or so. New strings typically take four to eight hours to fully settle, though they will be playable after the first retune.

Trim excess string length

Once the strings are tuned and have begun to settle, use wire cutters to trim the excess string length at the headstock. Cut the strings close to the tuning peg posts, but leave enough that the string does not slip out of the peg hole. Trim one string at a time and retune when ready after, since cutting removes tension.

Be careful not to cut so close that the string unravels or pulls free. If you are unsure how much to leave, cut conservatively—you can always trim more later, but you cannot put string back on.

Frequently Asked Questions

Do I have to change all six strings at once?

No. You can change strings one or two at a time if you prefer. Changing all at once lets you clean the fretboard and is faster overall, but changing them individually means your guitar stays in tune the whole time. Many players change all six at once for convenience.

What if a string breaks while I am winding it?

Stop when ready and remove the broken string. Insert a new string and start over with that one. Breaking usually happens if you wind too fast or if the string was already damaged. Wind slowly and keep steady tension on the string to avoid this.

How tight should the bridge pins be?

Push the bridge pin down until it is snug and the string cannot move, but do not force it so hard that you crack the pin or the bridge. The pin should sit flush with the bridge surface. If a pin is cracked or damaged, replace it with a new one before installing the string.

Why do new strings go flat so quickly?

New strings stretch as they are brought up to pitch and as you play them. This stretching is normal and expected. Play the guitar and retune several times over the first few hours, and the strings will stabilize. After that, they should hold tune much better.

Can I reuse old strings?

Technically yes, but old strings sound dull and are more likely to break. It is not worth the risk or the poor tone. Buy a new set and discard the old ones, or recycle them if your area has a metal recycling program.
