Should I be worried about the crack?
I would get it glued to prevent further separation.
Or do it yourself if you feel confident. It's not difficult:
-Make sure the separation will close with pressure. You can use epoxy glue if you prefer.
-Remove the tuners adjacent to the repair.
-Make sure you have a wood block to fit the back and front of the headstock at the repair.
-Tape off near the crack/separation (glue will damage the guitar finish if it bleeds)
-Have a clamp and some wax paper handy and ready to use. You dont need a big clamp. Hard to handle.
-Using some Medium to Thick CA glue, "5 second glue". (Hobby shop, 'Bob Smith Industries' is good quality, but most will work) It wicks into the crack very well.
-Put in the glue, quickly lay wax paper, backed by wood blocks, and clamp it fast!
(this is why you need everything cut and adjusted ready to go!)
JUst take your time preparing and use whatever feels best for the job.
