That’s got to be poor gluing, i treat my guitars like shite, they fall over all the time, my poor mexi strat takes a beating! 😆 still works perfectly!
It would take an incredible amount of force to snap the body of a well made guitar.
IMO, that’s definitely a manufacturing error.
Pretty sure wood glue is meant to be stronger than the wood itself. So should defo be shattered as opposed to the glue just comming apart.
All fine and well saying you can fix it, it will be easy enough to re glue, and won’t affect the functionality/sound of guitar, but that doesn’t solve the body work issues that are a whole different ball game to get back to the original.
