What You Need Before You Start
Restringing an acoustic guitar takes about 30 to 45 minutes once you have the right tools and a new set of strings. You will need a new acoustic guitar string set (six strings, usually bronze or phosphor bronze wound), wire cutters, a string winder (optional but speeds up the process), a tuner, and a clean cloth. Most music stores sell complete restringing kits that include everything except the tuner.
Before you begin, lay out your workspace on a flat surface with good lighting. A guitar neck rest or rolled towel under the headstock prevents the guitar from rolling and protects the finish. Have a trash bin nearby for old string pieces—they are sharp and straightforward to lose in carpet.
Key Takeaways
- Remove all six old strings at once by loosening the tuning pegs, then pull them out of the bridge and headstock.
- Clean the fretboard and body while the strings are off, since you cannot reach these areas easily with strings in place.
- Insert new strings into the bridge first, then thread them through the tuning pegs, leaving slack for winding.
- Wind each string around its tuning peg in a downward spiral, keeping tension even so the string winds neatly without overlapping.
- Tune to pitch gradually over several hours, as new strings stretch and go flat repeatedly before they settle.
Removing the Old Strings
Start by loosening all six tuning pegs at the headstock. Turn each peg counterclockwise (when looking at the headstock from the front) until the string is slack enough to move by hand. You do not need to unwind them completely—just enough that the strings have no tension. This prevents sudden stress on the neck when you remove all the strings at once.
Once the strings are slack, pull each one out of the bridge at the body. Most acoustic guitars have bridge pins (small wooden or plastic pegs) that hold the strings in the bridge slots. Push these pins up and out from underneath, or gently pry them out with the edge of a wire cutter or a small flathead screwdriver. The string will come free once the pin is removed. Pull the string completely out of the bridge hole.
Now unwind the tuning pegs the rest of the way and pull the strings out of the headstock. Coil the old strings and discard them. With all strings removed, you have a clear view of the fretboard and body—this is the ideal time to wipe down both with a soft, dry cloth to remove dust and oils that accumulate under the strings.
Preparing the Bridge and Headstock
Before inserting new strings, inspect the bridge pins. If they are cracked, warped, or do not fit snugly in the bridge holes, replace them with new ones (usually included in string sets). Clean out any debris from the bridge slots with a dry cloth or soft brush.
Check that the tuning peg holes are clear and the pegs turn smoothly. If a peg is stiff, a tiny amount of lubricant designed for guitar hardware can help, but do not over-explore—excess lubricant collects dust. The pegs should turn with light resistance, not spin freely or bind.
Installing the New Strings
Start with the thickest string (the low E string). Insert the ball end (the small metal loop at one end of the string) into the bridge slot. The ball end goes into the hole first, then the bridge pin sits on top of it to hold it in place. Do not push the pin all the way down yet—just set it loosely so the string does not fall out.
Pull the string up toward the headstock, leaving about 2 to 3 inches of slack. This slack is where you will wind the string around the tuning peg. Thread the string through the hole in the tuning peg for that string. On most acoustic guitars, the three bass strings (thickest) wind on the left side of the headstock, and the three treble strings (thinnest) wind on the right side, but check your guitar's design to be sure.
Repeat this process for all six strings before you begin winding. Once all strings are threaded through the bridge and headstock, you are ready to wind them onto the tuning pegs.
Winding the Strings Onto the Tuning Pegs
Start with the low E string (thickest). Hold the string taut with one hand about 2 inches above the tuning peg hole, and turn the tuning peg with your other hand. The string should wind downward around the peg in a spiral, with each wrap sitting below the previous one. This downward spiral keeps the string organized and prevents overlapping, which causes tuning instability.
Wind slowly and keep light tension on the string as you turn the peg. A string winder (a hand-crank tool that fits over the tuning peg) speeds this up and keeps tension even, but winding by hand works fine if you go slowly. Aim for three to four wraps around the peg for the thicker strings and four to five wraps for the thinner strings. More wraps mean more friction, which can cause tuning problems; fewer wraps mean the string may slip.
As you wind, the string will gradually tighten and begin to rise in pitch. Stop winding when the string reaches approximately the correct pitch—you do not need to tune it perfectly yet. Repeat this process for all six strings. Once all strings are wound and roughly in pitch, push the bridge pins firmly into place. The pins should sit flush with the top of the bridge, holding the string ball ends securely.
Tuning and Stretching New Strings
Use a tuner to bring each string to pitch. Start with the low E string and work your way up to the high E string. New strings stretch as they are played, which causes them to go flat. Expect to retune every few minutes for the first 30 minutes, then every 10 to 15 minutes for the next hour or two.
After tuning, gently stretch each string by pressing down on it at different points along the fretboard and pulling slightly upward. This controlled stretching helps the string settle faster and reduces the number of times you need to retune. Stretch each string two or three times, then retune. Repeat this cycle for at least an hour, or until the strings hold pitch for several minutes between tunings.
New strings typically stabilize within 24 hours of playing, but they will continue to stretch slightly for a week or two. Do not be alarmed if the guitar goes flat overnight—this is normal. Keep the tuner handy and retune as needed. After a few days of playing, the strings will settle into their final pitch and require tuning only as often as any other guitar.
Common Mistakes to Avoid
The most common error is winding the string upward instead of downward around the tuning peg. This causes the wraps to overlap and the string to slip under tension, making the guitar impossible to keep in tune. Always wind downward in a neat spiral.
Another mistake is winding too many times around the peg. More than five wraps on any string creates excessive friction and makes fine tuning difficult. Fewer than three wraps risks the string slipping. Three to five wraps is the target for all strings.
Do not push the bridge pins in until all strings are wound and roughly in pitch. If you pin them too early, you cannot adjust string height or position if a string sits unevenly in the bridge slot. Also, avoid cutting the excess string length at the headstock until the strings have settled for at least a day—you may need to rewind if a string slips during the first few hours.
Frequently Asked Questions
How often should I restring my acoustic guitar?
Most players restring every three to six months with regular playing, or sooner if strings sound dull, feel rough, or break. Strings wear faster if you play daily or play with a heavy touch. If you play a few times a week, restringing every four to five months is typical.
Can I replace one string at a time instead of all six?
Yes, you can replace individual strings without removing all of them. However, restringing all six at once is faster and gives you a chance to clean the fretboard and body. If you replace one string, the others will be older and may sound slightly different in tone until they wear in together.
What if a string breaks while I am winding it?
Stop when ready and remove the broken piece. Insert a new string and start over with that one. Strings sometimes break during winding if they are defective or if you wind too tightly too quickly. Winding slowly and steadily reduces this risk.
Do I need to loosen the truss rod before restringing?
No. The truss rod controls neck relief and should not be adjusted during a routine restringing. Loosen the tuning pegs to reduce tension on the neck, but leave the truss rod alone unless you are addressing a specific neck problem like fret buzz or excessive relief.
How tight should the bridge pins be?
Push the bridge pins in firmly until they sit flush with the bridge top, but do not force them so hard that you crack the pin or the bridge. They should be snug enough that the string cannot move side to side in the bridge slot, but you should still be able to remove them by hand if needed.
