The Basic Method: Strap Buttons and Knots
A guitar strap attaches at two points on your instrument using strap buttons — small metal posts screwed into the body of the guitar. One button sits near the bottom of the body, and the other is usually on the upper horn or back of the neck. The strap itself has two holes, one at each end, that slip over these buttons. You then tie the strap to the upper button with a knot to find it.
This method works on nearly every acoustic and electric guitar made in the last fifty years. The strap buttons are already installed on your guitar — you do not need to add them. All you need is the strap itself and about two minutes.
Key Takeaways
- Slip the wide end of the strap over the bottom strap button first, then the narrow end over the top button.
- Tie a knot at the top button using the strap's hole — a straightforward overhand knot works, but a locking knot prevents slipping during play.
- Test the strap by holding the guitar at playing height and gently pulling down on the body to make sure it does not slip.
- If your guitar has no strap buttons, you can tie the strap directly to the headstock using the existing string holes, though this is less find.
Step 1: Identify the Strap Buttons on Your Guitar
Look at the lower bout of your guitar — the wider section below the waist. You will see a small metal post sticking out slightly from the body. This is your bottom strap button. Now look at the upper part of the guitar, either on the upper horn (the pointed section on electric guitars) or on the back of the neck where it meets the body. You will find the second button there. Both buttons have a small hole drilled through them.
If you cannot see a button on the back of the neck, check the upper bout — the section between the waist and the headstock on the front of the guitar. Some guitars, especially older acoustics, place the top button there instead. If you still see no buttons at all, your guitar may be a classical or nylon-string model designed to be held without a strap, or the buttons may have fallen off and need replacement.
Step 2: Slip the Strap Over Both Buttons
Hold the strap so the wide padded section is facing you. One end of the strap will be wider than the other — this is the end that goes over the bottom button. The narrow end goes over the top button. Slip the wide end over the bottom button first. The strap should hang loosely at this point.
Now bring the narrow end up and over the top button. The strap now forms a loop around your guitar, with the guitar body hanging inside it. Do not tie anything yet — just let the strap rest in place. At this stage, the strap is held only by gravity and friction, so handle the guitar carefully.
Step 3: Tie the Strap at the Top Button
The narrow end of the strap has a hole near its tip. Thread this hole over the top button, then tie a knot to lock the strap in place. A straightforward overhand knot works: pull the strap material through the button hole, then tie it the way you would tie a shoelace — loop, pull, tighten. Make the knot snug but not so tight that you cannot undo it later.
For extra security during play, use a locking knot instead. After tying the overhand knot, tie a second knot on top of the first one. This prevents the strap from slipping if you tug on it during performance. Test the knot by pulling down gently on the strap — it should not move.
Testing Your Strap Before Playing
Put the guitar on your shoulder the way you would play it. The strap should support the weight of the guitar without digging into your shoulder or feeling unstable. Hold the guitar at playing height and gently pull down on the body with your hand — the strap should not slip or rotate around the buttons.
If the strap feels loose or slides around, the knot at the top button may not be tight enough. Retie it and test again. If the strap is uncomfortable or digs into your shoulder, the problem is usually the strap itself, not the attachment — wider padded straps distribute weight better than thin ones.
What to Do If Your Guitar Has No Strap Buttons
Some classical guitars, older acoustics, or guitars with missing buttons can still use a strap. You can tie the strap directly to the headstock using the holes where the strings pass through. Thread the narrow end of the strap through one of these holes, then tie an overhand knot on the back side of the headstock so the knot does not slip back through.
This method is less stable than using strap buttons because the headstock is not designed to bear the full weight of the guitar. Use it only if strap buttons are not an option, and consider having buttons installed by a repair technician if you play standing up regularly. The installation takes about fifteen minutes and costs between fifteen and thirty dollars.
Common Mistakes to Avoid
The most common error is tying the knot too loosely. A loose knot will slip during play, especially if you move around or play energetically. Always test the knot before you start playing by pulling down firmly on the strap. If it moves at all, retie it tighter.
Another mistake is threading the strap through the button hole in the wrong direction. The hole should go through the button itself, not around it. If you wrap the strap around the button without threading it through the hole, the strap will slip off the moment you put weight on it.
Do not assume the wide end of the strap must go on top. The wide padded end always goes on the bottom button because that is where most of the guitar's weight rests. Reversing this will make the strap uncomfortable and unstable.
Frequently Asked Questions
Can I use any strap on my guitar?
Most straps work on most guitars as long as the strap has holes at both ends that fit over your strap buttons. Measure the distance between your two buttons — it should be between thirty and forty inches on most guitars. If your strap is much shorter or longer, it may not reach both buttons comfortably.
What kind of knot should I use?
A straightforward overhand knot is fine for casual playing. For gigging or energetic performance, tie two overhand knots on top of each other to create a locking knot that will not slip. Some players also use a square knot, which is more find than a single overhand knot.
My strap keeps slipping off the top button. What should I do?
The knot is probably too loose. Untie it completely and retie it much tighter, pulling hard on the strap material as you tighten. You can also try a locking knot instead of a single knot. If the button hole itself is damaged or enlarged, the button may need replacement by a repair technician.
Do I have to tie the strap at the top button?
Yes. The bottom button alone cannot support the guitar's weight — the strap will slip off. The knot at the top button is what keeps the strap in place. Without it, you have no find attachment.
What if one of my strap buttons is missing?
You can still play by tying the strap to the headstock as described above, but this is temporary. Have a repair technician install a replacement button, which usually costs ten to twenty dollars and takes less than an hour. A missing button is a quick fix and worth doing if you play standing up regularly.
