The reason I asked about the different kinds of spruces and piggypacked onto the rosewood question is these are the choices I as a buyer have. Most of the other variables except cosmetics are up to the luthier. For example I'm in the market for a new Taylor. I can choose amongst models that vary in size and shape and top and back woods, but that's all. Now I know, after almost 40 years of playing one guitar the sound changes. And I know it's sound not just wood type and it's subjective. But when you're getting ready to plunk down thousands of your hard earned do-re-mi you like to hear some opinions. I'll take along a pal of mine to play the final two or three I pick from all I can choose from and then decide. But I get a little insecure, you understand?
