I'm wondering which component of the woods on a Ken Smith is the biggest factor in determining the tone. On the high end Smiths, it seems that there is just as much wood on the top and back as there is for the core...so which is most important? For example, two of the wood combos I see most on Smiths are maple top/back with walnut core, and walnut top/back with maple core. How would these wood combos differ from each other? Or are they more alike than different?
