I should clarify; it's not the original neck, but it's a good neck and the Squier 77 with pearloid markers is pretty rare. I should have bought one back in the day.
They made quite a few of these Standards, some in some pretty neat colors, and I will confess that redburst body I find kind of hideous. On the bonus side, the whole thing looks brand-new.
The pickups are not upgradeable, but they sound quite nice, so as long as they are working you should be in good shape. But they are an odd size and nobody makes replacements, unless you can find what is known as the "Mexican spacing" EMG pickups. I don't know if those are still made nor can I tell you for certain that they fit, having not done it myself. Nor does anyone offer originals.
EDIT: on examination of the photo, the strings are VERY off center. Someone put that neck on wrong, looks like. I would give this one a miss.
