I think with the but under the scroll I can hold a sheet of sandpaper across to smooth it, and then do the same with a shirt to stain it... But I'm at a loss for how to smooth the peg box (which is very choppy and will be impossible to stain because of it).
You could get in there with a dremel type thing and try to clean it up. Maybe try staining it black and it will be less noticeable.
