How to Change Guitar Strings (Step-by-Step, No Guesswork)
You've been putting it off. Your strings are oxidized, they sound dull, they feel gummy, and you're pretty sure the last time you changed them was during a different season. Here's the exact process, adapted to whether you're on an acoustic or electric, in under 15 minutes.
What You Need
- A new set of strings (match the gauge you currently have if the guitar plays well)
- A string winder (the little plastic crank that speeds up tuning peg turns — $3, saves so much time)
- Wire cutters
- A tuner (our online tuner works in your browser)
- A clean cloth (for wiping the fretboard)
- Optional: lemon oil or fretboard conditioner for rosewood/ebony boards
Do You Have to Change Them All at Once?
Short answer: yes, change the whole set at once. The strings in a set are designed to balance each other's tension on the neck, and mixing old and new sounds weird. Plus you'll be taking them off anyway to clean the fretboard.
Long answer: if one string breaks mid-gig, swap just that one and finish the set. For home practice, do the full set.
Step 1: Loosen and Remove
Tune each string down using the tuning peg until the string is totally slack. The winder makes this a 5-second job per string. When the string is loose, unwind it off the peg completely.
For acoustics with bridge pins: pull each string up out of its hole. Then use a pliers (or the string winder's notch) to pull out the bridge pin. Don't force it — lever it gently.
For electrics: the string ends usually feed through the back of the body. Pull the bridge end of the string and the ball-end pops out the back.
Step 2: Clean the Fretboard
This is the moment. With all strings off, you have unobstructed access to the fretboard. It gets gunky from sweat, skin, and string oxidation. Wipe it down with a clean dry cloth. Stubborn gunk can be scrubbed gently with a dry toothbrush.
If you have a rosewood or ebony board (unfinished wood, looks like... wood), and the fretboard looks dry or feels rough, apply a tiny amount of lemon oil or fretboard conditioner on a cloth, wipe it in with the grain, then wipe off the excess. Once or twice a year is plenty.
If you have a maple board (glossy, lighter color, often finished), skip the oil — the finish seals the wood and you don't need conditioner. Just wipe clean.
Step 3: Install the New Strings
Open the pack. Most packs number the strings 1 (thinnest, high E) through 6 (thickest, low E). Start with the low E string (string 6).
For acoustics: thread the ball-end through the bridge hole, then insert a bridge pin into the hole with the groove in the pin pointing up toward the headstock. Hold the pin down and gently pull the string up until you feel the ball-end seat against the bottom of the pin.
For electrics: feed the string through the bridge from the back (or top, depending on your guitar) until the ball-end catches.
Step 4: The Winding Technique (This Is Where People Screw Up)
Feed the other end of the string up to its tuning peg. Here's the rule: you want 2-4 clean wraps around the peg post when you're done tuning to pitch. Not more, not fewer.
Before inserting the string in the peg hole, pull it a couple inches past the post, then back up toward the nut to give yourself slack. Insert the string through the peg hole. Hold the slack with one hand. Now turn the peg so the string wraps around the post going downward — new wraps forming below the previous wraps. Guide the string with your free hand so wraps don't cross over each other.
When you reach correct tension (close to the right pitch), you should see 2-4 neat wraps stacked down the post. Cut off any extra string sticking out with wire cutters.
Step 5: Tune Up and Stretch
Repeat for all six strings. Tune each one to pitch as you go, checking with a tuner. Once all strings are on and roughly in tune, stretch them. Grab each string with your fingers at the 12th fret and pull it away from the fretboard for a second. The string will go flat. Retune. Repeat this for each string 2-3 times.
Stretching pre-sags the strings so they hold tuning. Without this step, your fresh strings will go flat every five minutes for two days. With it, they're stable in about ten minutes.
How Often Should You Change Strings?
- Daily player: every 4-6 weeks. Your hands leak oil and sweat into the strings; dead strings come fast.
- 2-3 times a week: every 2-3 months. Keep a spare set on the shelf — a broken string mid-session is annoying, but a broken string when no spare exists is worse.
- Couple times a month: push to 3-4 months, then check. If they still feel smooth and sound reasonably bright, squeeze another month out of them. When they start feeling gritty underhand, that's the signal.
- Pro/gigging: before every show, or at minimum monthly. Dead strings on stage sound terrible, break more easily at the worst possible moment, and honestly just look bad.
- Coated strings (Elixir, D'Addario XS): 3-4x longer than uncoated — they justify the extra cost if you play frequently or sweat a lot.
A good rule: if you can see the string color has shifted (bright shiny to dull gray or spotty), or if the windings feel rough to the touch, it's time. Dead strings also don't intonate well, which means chords up the neck sound progressively worse.
After the Change
Fresh strings sound brighter and more resonant — almost too bright for the first hour of playing. They'll settle into their natural tone within a couple of sessions. Your tuning will also be more stable than it has been in weeks.
