At some point, all guitarists need to learn how to change the strings on their guitar. Sometimes you’ll be forced to change one when a string breaks. But usually, you’ll simply want to change them, as strings lose their brightness. For a newbie, restring your guitar may seem a little intimidating. But with the right tools, a little knowledge and some practice, you’ll be able to restring your guitar like a professional guitar tech.
You will need to set aside about an hour of time to do this correctly, but with practice you will know how to restring your guitar in about 20-30 minutes.
First thing to remember, do NOT remove all six strings at the same time. The guitar neck is designed to withstand the tension of the strings and if all of the tension is removed for any significant amount of time you could damage your guitar. I like to start with the outside strings and work my way to the middle to keep consistent tension on the neck.
The amount of time you leave between change strings varies depending on several factors. If you play your guitar regularly, then you might like to change your strings once a week or once a month.
Most Professional guitarists tend to change their strings before each gig. But in the end, it all comes down to a matter of personal preference. Something to bear in mind if you’re using your guitar for a gig, is that your strings need a few hours of play to break in properly. During this time, your strings will go out of tune as they stretch so you’ll have to retune.
Here is the list of tools and supplies you will need:
- A new set of strings (naturally!) Click here for info on string sizes
- A string winder (not required but very handy)
- A pair of wire cutters
- A guitar tuner (again, not required but helpful)
Anyway, here’s what you do:
Remove Old Strings
Remove the old strings by detuning the machine heads until the tension becomes loose enough to allow you to pull each string away from the headstock.
Another quick way to remove the old strings is to snip them using a pair of wire cutters. Be very careful if you do it this way, and make sure they are loose, since the bare ends of the strings can be sharp and easily flap around. Bare guitar strings are amongst the many things you DO NOT want to catch in your eye.
Reinstall New Strings
How you go about installing your new strings will usually depend on the type of guitar you have, as many guitars have slightly different methods. However, the strings are usually held in place at one end by fixtures behind or on the bridge, and at the other by turning the machine head on the headstock.
On most electric guitars the strings are either secured at the bridge end by an independent tailpiece (like most Gibson guitars), or passed through the body of the instrument from the back into an all-in-one bridge unit (like most Fender style guitars).
At one end of every steel string, you will find a tiny disc of metal around which one end of the string is wrapped. This is called the ball end.
Take the opposite end of the string and thread it through the fixture at the bridge.
Pull the string through until the ball end stops you from pulling the string any further.
Most electric and steel-string guitars use a similar system for securing strings at the machine head. The capstan to which the string is attached stands out vertically from the headstock. Strings can be passed through a hole in the side of the capstan.
The end is then passed around and under, trapping it in place when the machine head is tightened. Some capstans have vertical slots instead of holes. To use these, cut the string to length, and insert into the tip of the capstan. Then bend the string to one side and wind it around.
This leaves the string endings neat and tidy.
Tune the Guitar
Here’s what you do next: Slowly turn the machine head for each string, increasing the tension until the string becomes suitably tight.
To save yourself time and energy, you can use a cheap plastic string winder, which simply fits over the machine head allowing you to crank it along more quickly.
Tighten the Strings
Regardless of what kind of guitar you have, your strings need to be stretched after you’ve put them on. When you first tune your guitar, put your hand under each string around the pickup area or sound hole, pull the string a few inches away from the fretboard, then release it. If the pitch has dropped, retune and repeat the process. Keep doing this until all the strings stay in tune.
