thanks for the input guys
if it's strictly a cosmetic issue and not something that's likely to warp the neck overtime because of uneven string pull or, god forbid, snap the headstock clear off in the middle of a sick bend one day, I'm fine keeping it
I bought it second hand, checked the usuals but didn't think much of the slanted headstock at the time... don't really notice it while playing... it was only after seeing it laying down like in the photo that I noticed just how crooked it looks
might shoot an email to Gibson to see if they have any ideas since, to me, it clearly left the factory like this and isn't a result of mishandling the guitar, but I'm not holding my breath 🙂
