Colorado Blue Spruce
Colorado Blue Spruce grows in the same forests as Englemann here in Colorado. It is typically little stiffer than Engelmann and the grain shows more seasonal variability. It is a beautiful white wood that is stiff and light, ideal features for a soundboard wood. I use it a lot and some builders have used it in some very expensive guitars. Not a well-known wood, but one of my favorites, very similar in tone characteristics to Engelmann. Occasionally this wood has a pronounced "curl" or wave and is quite distinctive.
