The dreaded sound of a guitar neck cracking is something no guitar player wants to experience. It’s a common issue, particularly with guitars featuring an angled-back headstock. You might even consider this angled design a potential weakness in the construction. Let’s delve into why the Neck Of A Guitar, especially in the headstock area, is so susceptible to damage.
On guitars where the headstock is angled back, the point where this angle occurs is inherently weaker. Several factors contribute to this fragility, but primarily, it’s due to the direction of the wood grain and the thinness of the material at this juncture – often the slenderest part of the entire guitar neck. Adding to this structural vulnerability, many guitars incorporate a truss rod access channel in this very area. This channel effectively removes even more wood from an already delicate section, creating a prime location for breaks.

Guitar manufacturers are well aware of this potential problem and employ various methods to mitigate the risk. These preventative measures include:
- Multi-ply ‘sandwich’ necks: Constructing the neck from multiple layers of wood with alternating grain directions increases overall strength and stability.
- Relocated or reduced truss rod access: Moving the truss rod access point away from the headstock or minimizing the size of the channel can preserve more wood in the critical area.
- Scarfed headstocks: Joining the headstock to the neck using a scarf joint, which is a diagonal cut and glue joint, creates a stronger and less breakable angle compared to a single piece angled neck.
- Volute: Perhaps the most common solution, a volute is a carved bulge or thickening of wood at the neck/headstock joint. This added mass reinforces the weak point and significantly reduces the likelihood of breakage.
However, some manufacturers, like Gibson, haven’t consistently implemented these strengthening features. While a volute was introduced on many Gibson guitars in the late 1960s, it was later phased out, and its presence on modern Gibsons is inconsistent. Many current Gibson models lack a volute. While all guitars with angled headstocks carry some risk of breakage, Gibson guitars, particularly models like SGs and Les Pauls, are frequently seen for headstock repairs. It’s almost become a running joke in guitar repair circles that if Gibson were to consistently reinforce this area, repair technicians specializing in neck repairs would see a significant drop in business.
What to Do if You Break Your Guitar Neck
Accidents happen. If you find yourself with a cracked or broken guitar neck or headstock, don’t despair. In almost every scenario, the damage is repairable. Here’s a step-by-step guide on the immediate actions to take:
-
If the Headstock is Still Attached (Even Partially): If the headstock is still connected to the neck, even if only by the headstock veneer, the first and most crucial step is to immediately and very gently slacken the strings. Reducing string tension will minimize further stress on the damaged area. Carefully place the guitar in its case and take it to a reputable guitar repair professional as soon as possible.
-
If the Headstock is Cracked: Even with just a crack, follow the same procedure as above. Slacking the strings is paramount to prevent the crack from worsening. Seek professional repair promptly.
-
If the Headstock is Completely Detached: If the headstock has completely broken off, carefully wrap it in protective material like a bag or newspaper. Handle it with care to avoid further damage to the fractured wood splinters.
-
Do Not Attempt to Reattach the Headstock Yourself: Resist the urge to try and glue the headstock back on yourself immediately. A proper repair requires careful examination of the joint, removal of any loose splinters or debris, and precise alignment.
-
Collect Loose Splinters: Check for any wood splinters that have detached from the break. If you find any, collect them and place them in a small bag. These fragments are invaluable for achieving a clean and strong repair, like pieces of a jigsaw puzzle.

The Importance of a Professional Guitar Neck Repair
The initial repair of a broken guitar neck is critical. A poorly executed repair significantly increases the risk of the neck breaking again at the same point. Even normal string tension can be enough to pull apart a weakly repaired break. Furthermore, attempting to repair a previous, inadequate repair is considerably more complex, time-consuming, often more invasive, and ultimately more expensive.
The key takeaway is prevention – avoid breaking your guitar neck in the first place! However, if the unfortunate happens, ensure you entrust the repair to a skilled and experienced luthier or guitar repair technician.
Don’t hesitate to discuss the repair process with your chosen professional. A competent repair person will be happy to explain their planned approach. For instance, inquiring about the type of glue they intend to use is a worthwhile question. For most guitar neck repairs, traditional hot hide glue or aliphatic resin (wood glue) are typically the most appropriate choices. If a repairer immediately suggests using epoxy, it’s prudent to ask for their reasoning. While epoxy adhesives have specific applications in headstock repair, they are not generally the primary adhesive for these types of breaks due to their nature and penetration capabilities. Choosing the right adhesive and repair technique is crucial for ensuring the longevity and playability of your instrument after a neck repair.
