A guitar tips off its stand, and the headstock cracks at the neck. That sick feeling hits hard, but the break is rarely the end of the instrument.
It’s one of the most common repairs a luthier sees. A clean break, glued and reinforced well, can come back to full playing condition and hold for years.
Before you start, a fair warning. This is a tricky job, and if your guitar has real value or sentiment, an experienced luthier is the safer bet.
If you want to understand or attempt the fix, here’s the full repair step by step, including the right glue and tools.
How to Repair a Broken Guitar Headstock
The full repair is a sequence of nine steps: glue the break, reinforce it with splints, then fill and refinish so the joint disappears. Before diving in, it helps to watch the process done by someone experienced, so search out a reputable headstock-repair video to see the clamping and routing in action.
Step 1 - Assess the Damage
The first thing you want to do is assess the damage. A clean, single-line break across the neck is the most repairable.
You can try to glue the headstock back on alone, but chances are that won’t hold for long - the joint takes a lot of string tension, so you’ll need a stronger hold than glue by itself.
Step 2 - Glue the Headstock Back On to the Neck
The next step is to glue the headstock back onto the neck. Use a strong adhesive such as epoxy or superglue.
I wouldn’t recommend ordinary wood glue here, as it won’t hold well under string tension - you’d be better off just letting it break again than trusting a weak joint.
Step 3 - Clamp It Together to Dry
To make sure you get a strong hold, sandwich the headstock joint between two scrap pieces of wood and clamp it all together. The scrap wood spreads the clamping pressure and protects the finish.
Let it dry completely before doing anything else.
Step 4 - Remove the Clamps
After the epoxy, glue, or superglue has dried and hardened, remove the clamps and sand off any excess glue that squeezed out of the joint.
Step 5 - Route Out Channels for Splints
To truly strengthen the repair, you need to add wooden splints across the crack line. In this step, route out a channel on each side of the headstock to seat those splints.
The splints are what carry the load that glue alone can’t.
Step 6 - Add the Splints
After the channels have been cut, insert a splint into each side of the headstock. Make sure they’re nice and snug, glued firmly in place, before moving on.
Step 7 - Fill the Crack on the Headstock
Fill any remaining gap in the crack on the headstock. You can use superglue, epoxy, or wood filler for this step, depending on the size of the gap you’re closing.
Step 8 - Sand the Repair Smooth
Lightly sand the area after filling it to make it smooth. This takes away any sharp edges or high spots that could interfere with the repair or the finish.
It also helps to carve out the dreaded “glue line” by hand with a chisel so it blends into the surrounding wood.
Step 9 - Dress Up the Headstock for a New Look
Now that everything is smooth, it’s time to dress up the headstock. Stain it to match and do some very light sanding to give it a clean, finished look.
You can also add a new veneer to the face of the headstock if you want to hide the repair completely.

Should You DIY or Hire a Luthier?
A headstock break is a high-stakes repair. The joint sits where all six strings pull against the neck, so a weak repair will simply fail again - sometimes worse than the original break.
That’s why I recommend an experienced luthier for any guitar with sentimental or resale value.
A DIY repair makes the most sense on a cheap beater guitar you’re willing to experiment with, or if you already own clamps, a router, and have done finish work before. If the break is jagged, splintered, or runs into the truss rod channel, that’s well beyond a kitchen-table fix and into professional territory.
When in doubt, get a quote first - the assessment usually costs little and can save you from turning a repairable guitar into firewood.
Frequently Asked Questions
How long should you wait before removing the clamp from a reglued headstock?
Give it at least 24 to 48 hours. That’s plenty of time for the glue to fully cure and reach its maximum strength, and rushing it’s one of the easiest ways to ruin an otherwise solid repair.
How much does a headstock repair devalue a guitar?
If a buyer spots the repair while inspecting the guitar in a shop, it’ll knock the value down somewhat.
But if the work is clean and the repair isn’t obvious, there’s little to no real devaluation of the instrument as a whole.
How much does it cost to repair a broken guitar headstock?
The cost depends on how much damage the headstock has suffered - the more severe the break, the higher the price. As a rough guide, a professional headstock repair tends to start in the $200 range and climbs from there with complexity.
What glue should you use to repair a headstock?
A high-quality wood glue can work for a tight, clean break, but for a joint under this much string tension, a structural adhesive like epoxy or thin superglue generally gives a stronger, more reliable hold.
Final Thoughts
There are several ways to repair a broken guitar headstock, and most of them follow the same arc: glue the break with epoxy or superglue, reinforce it with splints, then fill and refinish. The headstock is restored by sanding it down and giving it a clean finish with stain and light sanding.
Done well, the end result is a guitar that functions like normal again, holds tune under full string tension, and shows little or no sign that a repair was ever needed. Done poorly, it’s a joint that fails the moment you bring it back up to pitch.
That’s the honest reason I keep coming back to the same advice: if the guitar matters to you, let a luthier handle the break. If it’s a cheap project guitar, take your time, use the right adhesive, and don’t pull the clamps early - patience is what separates a repair that lasts from one that lets go.
