it was really hard to get good pics of the area im talking about but look between d & g closer to d and you'll see a line in the fingerboard. what do you guys think? Crack or Normal Wood Grain?
What I would suggest: Grab the fingerboard, with your two thumbs on top on either side of the crack and *gently* flex the board back and forth. If it's a crack, you should see it open and close slightly. Obviously, you don't want to do this too forcefully or you could make it worse.
it is a check if it is boxed on the surface, when it reaches the edge it will become a crack. it will then be time to close it. it may not change for many years,just something to live with.
Yeah, Forester is right, it is a check. Those dense woods like ebony can develop checks if they were not dried carefully. If your bass is stored in a warm spot in your house like direct sun or near a radiator the FB can develop checks as well.
