Yes, red spruce has "certain" characteristics, but I've played very open and 3-D sounding guitars with red spruce as well as some that were a bit 2-dimensional, but they all had those "certain" characteristics in common. A couple of other things to consider with regard to wood is that most factory-made acoustic guitars are built to a specification. The wood is pre-selected and cut, often by CNC to a certain size, thickness, shape, etc. Then all the pre-cut pieces are glued together by a technician. Other than some basic trimming, there often isn't much going on in terms of optimizing the carve of the bracing. The tone of the guitars produced this way usually fall on a bell-shaped, where the majority are in the middle (average, but good sounding), but some are on the left tail of the curve (less the average sounding) and some are on the right tail of the curve (exceptionally good sounding). However, master guitar builders can produce really good sounding guitars based on the quality and characteristics of the wood. They know how to shape and place bracing, determine optimal top thickness based on the feel and sound of the woods they've selected to build that specific model guitar. They will tap tune and use chladni patterns to help guide them. So there's science, art, and professional experience going into a luthier-built guitar. They can consistently make some pretty spectacular sounding guitars using the usual Sitka spruce top and Indian rosewood body (or any other wood for that matter), while the factory-made versions fall on that bell-shaped curve.
