The recent thread on Les's new 30th Anniversary CU24 (http://prsguitars.com/forum/showthread.php?13417-Out-For-Delivery-30th) got me thinking about this. Why/when is the decision made to "bookmatch" the top on the guitar versus just using the one piece. It seems to me that the effect that is trying to be achieved with two pieces is a high degree of symmetry anyway. That top on Les's guitar is a GREAT example. You have to look closely to see it's not one piece. Obviously, many guitars DO get made with one piece tops but the overwhelming majority do not. I'm just curious. Does it take more effort to make one piece tops? Waste more wood? Just wonderin'.
