Spruce has long been a popular choice of wood for the tops of guitars and mandolins. It is only recently that it has started being widely used for ukuleles such as in this range by Kala. But it's a good choice of wood for certain types of player. It produces a very immediate and punchy (which means it doesn't have the rounded, rich tone of other woods) - this makes it great for players who really like to play loud and hard.
