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 (the gauge does not matter for your first time—standard 80/20 bronze or phosphor bronze work fine), a wire cutter, a string winder (optional but saves your wrist), and a tuner. You may already have a tuner on your phone; a clip-on tuner costs $10 to $20 and clips to the headstock.

Before you start, loosen all six tuning pegs at the headstock by turning them counterclockwise. This removes tension from the old strings so they come out easily and safely. Loosen them until the strings are slack but do not need to come completely off yet.

Key Takeaways

  • Remove old strings by loosening the tuning pegs, then unwind them from the bridge pins at the body and pull them out of the headstock holes.
  • Insert new strings starting with the thickest string (low E) at the bridge, securing it with a bridge pin, then thread the other end through the headstock hole and wind it onto the tuning peg.
  • Wind each string so it wraps two to three times around the tuning peg post, keeping tension even so the string does not slip.
  • Tune the guitar to pitch using a tuner, then gently stretch each string by pulling it away from the fretboard to help it settle and hold tune longer.
  • New strings take 24 to 48 hours to fully stabilize, so expect the guitar to go out of tune several times before it settles.

Removing the Old Strings

Once the tuning pegs are loose and the strings are slack, move to the body of the guitar. At the bridge (the wooden piece glued to the top of the body where the strings attach), you will see six bridge pins—small wooden or plastic pegs that hold the strings in place. Pull each pin straight up and out. They may require a gentle wiggle, but they should come free without force.

With the bridge pins removed, the old strings will fall away from the bridge. Pull them out of the headstock holes at the top of the guitar. Discard the old strings. Wipe down the fretboard and body while the strings are off if you want to clean the guitar—this is the easiest time to reach those spots.

Installing the First String (Low E)

Start with the thickest string, which is the low E string (the 6th string). Take the ball end of the new string—the small metal sphere at one end—and insert it into the bridge hole closest to you as you look at the guitar from the front. The ball end sits inside the body, below the bridge.

Push the bridge pin into the hole on top of the bridge, directly above where the string enters. The pin holds the string in place and prevents it from sliding out. The groove in the bridge pin should face the string so the pin does not cut into it. Push the pin down firmly until it is snug and level with the bridge.

Now take the other end of the string and thread it through the hole in the headstock post for the low E string. On most guitars, the low E post is the one closest to the body. Pull the string taut but not tight—you want it straight, not under heavy tension yet.

Winding the String onto the Tuning Peg

Hold the string taut with one hand and use the other hand to turn the tuning peg counterclockwise (when looking at the headstock from the front). As you turn, the string will wind around the post. Keep the string straight and under light tension so it wraps neatly in parallel lines, not crossing over itself.

Wind until the string has wrapped around the post two to three times. Too few wraps and the string will slip; too many and you waste string and create tuning instability. After two to three wraps, the string should be close to pitch but not yet at the correct note. If you have a string winder, fit the handle over the tuning peg post and crank it—this is much faster and easier on your hand than turning by hand.

Once the string is wound, use a wire cutter to trim the excess string sticking out past the post. Leave about a quarter-inch so the cut end does not unwind, but trim close enough that the excess does not get in your way as you work on the next string.

Installing Strings Two Through Six

Repeat the same process for each remaining string, working from the thickest to the thinnest. The order is: low E (6th), A (5th), D (4th), G (3rd), B (2nd), high E (1st). Each string goes into its corresponding bridge hole, gets pinned down, threads through its headstock hole, and winds onto its tuning peg.

As you work, keep the already-wound strings under light tension by turning their tuning pegs slightly if needed. This helps the new strings sit properly and prevents the bridge from tilting. The bridge should stay perpendicular to the body throughout the process.

For the three thinner strings (G, B, and high E), the tuning pegs on most acoustic guitars are on the opposite side of the headstock from the thicker strings. Thread these strings through their posts and wind them in the same way—two to three wraps, neat and parallel, then trim the excess.

Tuning and Stretching the New Strings

Once all six strings are wound and trimmed, use your tuner to bring each string up to pitch. Start with the low E string and work your way up to the high E. Turn the tuning peg slowly and watch the tuner display until the string reaches the correct note. Do not crank the pegs quickly—new strings are under stress and can break if you over-tighten them suddenly.

After tuning all six strings to pitch, gently stretch each string by pulling it away from the fretboard, about an inch or two out from the body. This helps the string settle into the bridge pin and bridge slot, and it speeds up the stabilization process. Retune after stretching because the strings will have gone slightly flat.

Repeat the stretch-and-retune cycle two or three times. Each time you stretch, the strings will hold their pitch a little better. This small step saves you from constant retuning over the next day or two.

What to Expect in the First 24 to 48 Hours

New strings take time to stabilize. Even after you stretch them, they will continue to go flat gradually over the next day or two. This is normal and does not mean you did something wrong. The strings are settling into their final position at the bridge, nut, and tuning posts.

Tune the guitar again before you play it the next day, and possibly once more the day after that. By the third day, the strings should hold their pitch much more reliably. After a week, they will be fully stable. Avoid tuning up to pitch too aggressively during this settling period—gentle adjustments are safer for new strings.

Frequently Asked Questions

What happens if I wind a string the wrong direction on the tuning peg?

If you turn the peg clockwise instead of counterclockwise, the string will tighten instead of loosen, and you will quickly over-tighten it. Stop when ready and turn the peg the other way. The string will not break from a few turns in the wrong direction, but it will if you keep going. Clockwise tightens; counterclockwise loosens.

Can I replace one string at a time, or do I have to remove all six at once?

You can replace strings one at a time if you prefer. Loosen the tuning peg for that string, remove the bridge pin, pull out the old string, and install the new one. Replacing one at a time is slower but easier if you are nervous about the process. The bridge will not shift or tilt as long as you keep the other strings under tension.

Why did my string break when I was winding it?

Strings break during winding usually because you turned the tuning peg too fast or too far, over-tightening the string suddenly. New strings are under stress and can snap if tension builds too quickly. Wind slowly and stop every few turns to check the pitch with your tuner. If a string breaks, remove it, discard it, and install a fresh one from the pack.

How tight should the bridge pin be?

Push the bridge pin down until it is snug and sits level with the bridge surface. It should not require force or a tool—your thumb and fingers are enough. If you have to hammer it or use pliers, something is wrong; check that the string ball end is seated properly inside the bridge hole. The pin should feel firm but not strained.

Do I need to change the strings all at once, or can I wait until one breaks?

You can wait until a string breaks, but replacing all six at once is more efficient. Old strings lose brightness and go out of tune more easily as they age. If you replace them all together, the guitar will sound fresher and stay in tune better. If you replace strings one at a time as they break, you will eventually have a mix of old and new strings, which can sound uneven.
