Of course other headstock designs can break...you can get anything to break if you try hard enough. But there is a verifiable reason why Gibson headstock design is seen as problematic. It's a design issue pure and simple. I worked with a very well known vintage guitar restorer for six years. I've seen my share of old Gibsons and Fenders (in fact I've had my hands on two '59 bursts) and I would say that well over 50% had headstock repairs. I've seen a '62 Strat headstock that was broken as a result of it being smashed on stage...that's the only Fender headstock problem I encountered in probably a couple hundred gutiars) I personally know several people who's Gibsons have fallen over and snapped at the headstock. These aren't exaggerated urban myths..... This typically does not happen with a design that incorporates a volute at the transition from neck to headstock or in a Fender style design. Just the facts.
