what hind of wood is the top of this bass

I'd guess it's bubinga ...wish the picture was bigger...possibly flame walnut, but it looks  a little light to me for walnut, though that depends on how well exposed the picture is. Mica will probably know.
 
Valentino

I think I second the walnut guess

the answer is..... Flame Walnut top, Maple accent veneer, Mahogany body.
