Body looks more like oak to me.
I could be mistaken but here's my 2 cents...
Red oak and ash are difficult to distinguish when stained. Often ash is used as a substitute or side by side with red oak in modern furniture and cabinet applications. White oak is/was used in real Craftsman furniture (Stickley, etc) and also barrel making because it is watertight; it resembles neither ash or red oak in appearance IMHO. Red oak began replacing white when white became rare and prices skyrocketed, before that its primary commercial use was as railroad crossties and firewood. I'm not that familiar with European woods so this could very well be a variety of oak unknown to me.
In the US at least ash is more often guitar wood so I made the ash assumption...swamp ash because of the very wide grain. If it is it would be a very light body which I prefer. I'm also one of those guys that believe in the voodoo of one piece bodies and thin finishes.
These swamp ash basses weigh 8 and 7 lbs. The Jazz body is one piece. The Leo Sting Ray behind it is 3 and weighs 12 lbs, made of 'northern ash', baseball bat wood.
