Or get a veneer to cover the top...The only way to lay out the body shape on the blank would be at an angle because the blank is just wide enough, but the body is offset. Looking at the face of the body (with the neck to right) the grain could not run horizontally. Not really a problem if it was a solid colour, but I wouldn’t build a new bass that way.
Some places you just want to be there and say nothing. That is one of those places.
