This is what sanded basswood looks like. The upper body contour also has a veneer or something over it, which doesn't match the rest. The surface also looks a little dark, from the sanding dust getting in the grain (original color was black).

Warmoth's page has this to say about basswood:
"This is a lighter weight wood normally producing Strat® bodies under 4 lbs. The color is white, but often has nasty green mineral streaks in it. This is a closed-grain wood, but it can absorb a lot of finish. This is not a good wood for clear finishes since there is little figure. It is quite soft, and does not take abuse well. Sound-wise, Basswood has a nice, growley, warm tone with good mids. A favorite tone wood for shredders in the 80s since its defined sound cuts through a mix well."
