As the wood in a guitar ages it gets more responsive.
There is one thing that a quality maker never underestimates. That is in aging the wood.
Why might this be the case?
Imagine the fresh woods as they sit after harvesting the trees. The wood is full of sap and water. As the water evaporates, and as the saps congeal into resins, the wood changes shape and shrinks. If you have ever purchased a cheap item make of fresh wood, you can immediately see the result. The pieces cease to fit together properly, and cracks may appear.
A guitar has delicate spatial relationships between the instrument, its several independent parts and the strings. Imagine a properly set up guitar made from fresh wood. The instrument will bend, sometimes influenced by the tremendous pressures in ways that will not only make it unplayable in terms of initial set-up, but also shift in ways that will cause cracks. The instrument becomes ornamental if it has any use at all.
