Yea, I got an epiphone les paul a few years old and not taken care of, the neck is completely warped. Any way to fix this?

adjust the truss rod if its not too serious, theres a little truss rod cover on the headstock(a little plastic plate) and you take that off, then use a screwdriver to turn it, it will bend the neck back provided its not too bad of a bend

EDIT: what kind of Epiphone is it, if it has a bolt-on neck then you can change the neck out for a different one
