The natural bodies I have seen have been made from aesthetically appealing cuts of wood, but most alder is ugly. Very ugly.
Since your body is sunbursted, you should be able to see what kind of grain you are dealing with, unless there is a thin veneer over it. Does it look ok to you?
Keep in mind that lower priced bodies are often made up of four or five pieces of wood, randomly joined together, because it is less expensive to use pieces of scrap than to do a nice one or two piece construction. This doesn't look very nice if you don't cover it up with a finish or veneer top.
If you get lucky, you can pull off something like this. http://unofficialwarmoth.com/index.p...5303#msg305303
