Do I have to use quartersawn wood for the back and sides of my acoustic guitar?
A. Quartersawn wood is the most dimensionally stable, but some woods like birds-eye maple must be flat-sawn for the figure to show. If you have some gorgeous or rare flat-sawn wood that you want to use, it may well be worth the risk; if it’s an inexpensive piece of a common wood, you may be risking the longevity of your guitar for no good reason.
