J200 Top

J200 Antique natural. Does any body know why for publicity photos, most J200 models are shown with perfectly bookmatched spruce tops. However mine (since out of the box 18 months ago) and others on display on websites and stores show two distinct colours for the top either side of the centreline of the bridge, clearly showing the 2 pieces of the top.

Since the 2 pieces of the top are bookmatched, the light hits the grain of each piece at a different angles relative to each other. Professional photographers can work around such issues to negate this effect. There is nothing wrong with your guitar.

All guitars with bookmatched tops will display this to varying degrees. Nice guitar, btw.

"Bookmatching" means that a thicker piece of wood is re-sawn into two thinner pieces, then effectively folded open to create a wider surface. As '57classic says, light then reflects off the grain of each side differently, so that the color can look different even though it is exactly the same piece of wood. In a bookmatched top or back, the grain pattern on either side of the centerline joint should be a mirror image of the other side. Over time, as the finish darkens somewhat, this will become less noticeable.

 

It is not a flaw.

I agree; it's grain "runout". This happens when the grain is not perfectly perpendicular to the surface of the top. If you look at the grain on the edge of the soundhole, you might pe able to see the the lines are slanting somewhat. If it is very severe it could be structurally detremental, but that is not the case with mild runout. The top is indeed bookmatched, but the light is reflected differently by the two halfs. If the guitar is turned upside down, the dark and light halves will switch place.
