Re: can the neck on this Gio be repaired? It has a couple of dead spots
it seems like it might be fixable. you may have a few high frets, but it seems more likely you need a good truss rod adjustment. Most guitar necks bow were the headstock pulls up and back toward the top of the body, it would seem your neck has the opposite bow where the neck back bows and the headstock dips and pulls toward the back side of the guitar.
as long as the neck isn't twisted in a circular fashion it should be fixable. I have only ever had one guitar out of a hundred or more that had a twisted neck. I have it now and have removed the fretboard. I plan on sanding the neck down level again from the fretboard side, making the trussrod channel deep enough the fit a new trussrod and then glue on a new fretboard, and then a full fret job.
