What You Need Before You Start
Stringing an acoustic guitar takes about 15 to 20 minutes once you have the right tools. You will need a new set of acoustic guitar strings (bronze or phosphor bronze are standard), wire cutters, a string winder (optional but speeds up the process), and a tuner. Lay the guitar on a flat surface or hold it between your knees so both hands stay free.
Before you begin, decide whether to remove all the old strings at once or replace them one at a time. Removing all strings at once lets you clean the fretboard and bridge, but takes longer. Replacing one string at a time keeps the neck under tension and takes less time overall. Either method works—choose based on whether you want to clean your guitar.
Key Takeaways
- Remove the bridge pins (the small pegs holding strings in place at the bridge) by gently prying them up with a string winder or coin, not by yanking the strings.
- Thread each new string through the bridge hole, replace the bridge pin, and wind the string around the tuning peg until it is tight enough to hold pitch.
- Wind the string so it wraps downward on the tuning peg post, creating two to three neat coils before you tune to pitch.
- New strings go sharp and flat unpredictably for the first few hours, so expect to retune several times before they stabilize.
- Trim excess string length at the headstock once the string holds pitch, leaving about a quarter-inch of slack so the string does not slip.
Remove the Old Strings and Bridge Pins
Start by loosening the tuning pegs at the headstock. Turn each peg counterclockwise until the string is slack enough to remove by hand. You do not need to unwind them completely—just enough that the string comes free without resistance.
Once the strings are loose, remove the bridge pins. These are the small cylindrical pegs that sit in holes along the bridge and hold the strings in place. Gently pry each pin upward using a string winder (most have a notch designed for this), a coin, or a small flathead screwdriver. Do not hammer or force them—they should come out with steady, gentle pressure. The old strings will fall away once the pins are out.
If you removed all the strings, wipe down the fretboard and the area around the bridge with a soft cloth. This is the easiest time to clean your guitar.
Insert the New Strings at the Bridge
Acoustic guitar strings come in a set of six, usually labeled from thickest (low E) to thinnest (high E). Start with the thickest string. Thread the ball end (the small metal loop at one end) through the bridge hole closest to the low E side of the bridge. The ball end sits inside the guitar body, and the string itself lies across the bridge.
Replace the bridge pin in the same hole. The pin should sit snugly and hold the string in place without crushing it. The groove in the bridge pin should face the string so the pin does not cut into it. Repeat this process for all six strings, working from the thickest to the thinnest.
Pull each string taut toward the headstock as you go. This keeps the strings organized and makes it easier to see what you are doing. Do not tune to pitch yet—you are just getting the strings in place.
Wind the Strings Around the Tuning Pegs
Start with the thickest string (low E). Pull the string straight up to the tuning peg post on the headstock. Leave about two inches of slack between the bridge and the tuning peg. This slack gives you room to wrap the string neatly.
Insert the string through the hole in the tuning peg post. Most acoustic guitars have the hole running horizontally through the post. Pull the string so it is snug but not tight, then begin turning the tuning peg counterclockwise. As you turn, the string will wrap around the post. Guide the string with your free hand so it wraps downward (toward the body of the guitar) and stays parallel to the other wraps. Aim for two to three neat coils before the string becomes tight.
A string winder speeds this up significantly. Fit the winder over the tuning peg post and turn the handle. The winder will wrap the string automatically while you guide it. This is faster and produces more consistent wraps than turning by hand.
Once the string is wound, tune it to pitch using a tuner. Repeat this process for all six strings, working from the thickest to the thinnest.
Trim the Excess String and Tune Again
Once all strings are wound and tuned to pitch, trim the excess string at the headstock. Leave about a quarter-inch of slack so the string does not slip off the post. Use wire cutters to cut cleanly. Be careful not to cut into the tuning peg or the post itself.
New strings stretch and shift as you play them, so expect the pitch to drop and rise unpredictably for the first few hours. Retune every 10 to 15 minutes for the first hour. After that, the strings will settle and hold pitch more reliably. It usually takes 24 hours for new strings to fully stabilize.
Common Mistakes to Avoid
The most common mistake is winding the string upward instead of downward on the tuning peg post. This creates a sharp angle that can cause the string to slip or break. Always wind downward, away from the body of the guitar.
Another mistake is leaving too much slack between the bridge and the tuning peg. This makes the string harder to wind neatly and can cause tuning problems. Two inches of slack is the right amount.
Do not overtighten the bridge pins. They should sit snugly but not so tight that they crush the string or crack the bridge. If a pin is hard to remove later, you have tightened it too much.
Finally, do not expect new strings to stay in tune when ready. Stretching and settling is normal. Retune several times in the first few hours and again before you play seriously.
Frequently Asked Questions
How often should I change my acoustic guitar strings?
Most players change strings every three to six months, depending on how often they play and how hard they play. If you play daily, change them every three months. If you play a few times a week, six months is reasonable. Strings sound duller and feel rougher as they age, so change them when the tone no longer satisfies you.
Can I reuse the bridge pins from my old strings?
Yes, as long as they are not cracked or damaged. Rinse them with water and let them dry. Bridge pins are inexpensive, so if any are chipped or worn, replace the whole set. Damaged pins can slip or damage the bridge.
What if a string breaks while I am winding it?
Stop when ready and remove the broken string. Unwind what remains from the tuning peg and pull it out of the bridge. Replace it with a new string from your set and start over. Strings usually break because they are wound too tightly or because the bridge pin is pinching them, so check your technique on the next string.
Do I need a string winder, or can I wind by hand?
You can wind by hand, but a string winder makes the job faster and produces neater wraps. A basic winder costs five to ten dollars and is worth the investment if you change strings regularly. If you only change strings once or twice a year, winding by hand is fine.
Why do new strings sound different from old ones?
New strings are brighter and have more sustain because the metal is clean and the windings are tight. As strings age, they accumulate dirt and oils from your fingers, and the windings loosen slightly. This dulls the tone. New strings also take time to settle, so the tone will change slightly over the first 24 hours as they stretch.
