Will sanding a roasted body change the color of the wood? I understand the roasting process  stabilizes the wood and that a roast guitar body can be finished with a oil finish. But I don't particularly like the dark color of the wood after roasting. If I lightly sand it can I get beneath the outer shell and get to a lighter color? If I do this will it harm the benefits from the roasting process? If I sand certain areas of the body to remove wood to gain greater access to the neck on both horn scoops will these areas look materially different in color than the rest of the body? Thanks.
 
The wood is cooked and, more to the point, the sugars in it are caramelized all the way through.  Assuming the roasted lumber hasn't been sitting a long time where it could have darkened due to sun exposure, the inside should be the same color as the surface.
 
Thanks for the info. So this is one of those good news, bad news situations. Bad new I can't lighten the color of the body by a light sanding. The good news I can make major  changes by deep sanding areas of the body and I won't end up with a two tone body.
 
If you want it lighter, you could use a two-part wood bleach.  Practice your procedure on scrap.
