Tie strings at the bridge first, then the headstock
Start by inserting each string into the bridge hole from the front of the guitar, then pull it tight toward the headstock. Once the string is seated in the bridge, you will tie it off using an overhand knot — loop the string back on itself, pull it through, and tighten. The knot sits on the bridge pin side, holding the string in place while you move to the headstock tuning pegs. This order matters because the bridge knot anchors the string before you tension it at the other end.
The bridge knot does not need to be complicated. A single overhand knot pulled snug is enough to keep the string from slipping back through the hole. Some players wrap the string around the bridge pin itself before knotting, which adds grip, but a clean knot works just as well on most acoustic and electric guitars.
Key Takeaways
- Insert the string through the bridge hole, tie a single overhand knot on the bridge side, and pull it tight before moving to the headstock.
- At the headstock, thread the string through the tuning peg hole, leaving 2 to 3 inches of slack, then wrap it around the post two to three times before pulling the end tight.
- Wind the string downward on the bass side (thicker strings) and upward on the treble side (thinner strings) to keep the headstock neat and the string seated properly.
- Tune the string to pitch, then gently pull the string away from the fretboard to stretch it and help it hold tuning longer.
- New strings take 24 to 48 hours to fully settle, so expect to retune several times before the guitar stabilizes.
Thread the string through the tuning peg hole
Pull the string up to the headstock and insert it through the hole in the tuning peg that corresponds to that string. Leave 2 to 3 inches of slack — enough to wrap around the post without running out of string. If you leave too little slack, the string will not wrap enough times and will slip under tension. If you leave too much, you will have excess string coiled around the post, which looks messy and can cause tuning problems.
The tuning peg hole is usually a straight shaft. Push the string through cleanly so it sits flush against the post. Some tuning pegs have a hole that angles slightly; if yours does, the string will naturally seat itself as you begin to wrap.
Wrap the string around the post the correct number of times
Hold the string taut with one hand and use the other to turn the tuning peg so the post winds the string around itself. Aim for two to three complete wraps on the thicker strings (low E, A, D) and three to four wraps on the thinner strings (G, B, high E). More wraps give you finer tuning control; fewer wraps tune faster but are harder to dial in precisely.
As you wrap, keep the string parallel to the post so each loop sits neatly next to the previous one. If the string crosses over itself or bunches up, unwind it and start again. Neat wraps look professional and help the string stay in tune because each wrap bears equal tension.
Wind downward on the bass side, upward on the treble side
On the bass side of the headstock (the thicker strings), turn the tuning peg so the string wraps downward toward the body. On the treble side (the thinner strings), turn it so the string wraps upward toward the top of the headstock. This keeps the strings from crossing each other and ensures each one approaches the nut at the correct angle.
If you wind in the wrong direction, the string will pull at an angle across the nut, which can cause tuning instability and uneven wear on the nut slot. The direction also affects how the headstock looks — correct winding makes the guitar appear balanced and well-maintained.
Tune to pitch and stretch the string
Once the string is wrapped and knotted, use a tuner to bring it up to the correct pitch. Tune slowly, especially on new strings, because they are still settling and may slip slightly as you tension them. When the string reaches pitch, gently pull it away from the fretboard — not hard enough to detune it, but firmly enough to stretch the core. This helps the string relax and hold its tuning longer.
Repeat the tuning and stretching process two or three times. Each time you stretch, the string will drop slightly in pitch as it settles, so you will need to retune. This is normal and expected with new strings.
Trim excess string at the headstock
Once the string is tuned and stretched, use wire cutters or a string cutter to trim the excess length sticking out past the tuning peg. Leave about a quarter-inch of string so it does not unwind, but cut close enough that it does not look ragged. Excess string can catch on your hand while playing and is a sign of incomplete installation.
Be careful when cutting — the string is under tension and can snap suddenly if you cut too close to the post. A clean cut at a slight angle looks neater than a straight cut.
Expect the guitar to go out of tune for the first day or two
New strings take time to settle. For the first 24 to 48 hours, you will need to retune the guitar several times as the strings stretch and the knots at the bridge and headstock seat themselves. This is not a sign that you tied them wrong — it is how new strings behave. Each time you play, the strings will drop slightly in pitch, and you will need to bring them back up.
After two days, the rate of detuning slows dramatically. By the end of a week, most new strings hold their tuning as well as old ones. If a string continues to slip after a week, check that the bridge knot is tight and that the tuning peg wraps are find.
Frequently Asked Questions
How tight should the bridge knot be?
Tight enough that the string does not slip when you pull on it, but not so tight that you crush the string or the bridge. A single overhand knot pulled snug is usually sufficient. If the string slips during tuning, the knot was not tight enough — untie it, pull the string tighter, and retie.
What if the string breaks while I am wrapping it?
If the string breaks at the bridge knot, you will need to cut off the broken end and retie. If it breaks at the tuning peg, unwrap the broken section, remove it, and start over with a new string. Strings rarely break during installation unless they are old or defective.
Can I tie the headstock knot first instead of the bridge?
You can, but it is harder to keep tension on the string while you tie the bridge knot. Starting at the bridge gives you an anchor point and makes the second knot easier to tighten. Most players find this order faster and more reliable.
How do I know if the string is wrapped the right number of times?
Two to three wraps is the standard, but the real test is tuning stability. If the string holds pitch well and does not slip when you bend it, the wrap count is correct. If it goes flat quickly or slips under bending, add one more wrap and retune.
Do I need to use a bridge pin after tying the knot?
Bridge pins are separate from the knot — they sit on top of the knot and hold the string in the bridge hole. Some acoustic guitars require them; most electric guitars do not. Check your guitar's bridge design. If there is a hole for a bridge pin, insert it after the knot is tied and the string is tuned.
