Because due to moisture absorption the free part of the fingerboard goes down, the opposite happens when the environment becomes dry (this is an effect that takes a few days, it is not immediate). The fingerboard will become convex (or if you prefer, a bump would form at the end of the neck, which is about halfway up the fingerboard) if it were perfectly straight at the start, if it were with a scoop it would flatten without becoming convex, hopefully. It depends on the starting conditions. On thin fingerboards these movements are usually more noticeable. You can verify this with a simple "scientific" () test, try to wet the fingerboard surface and see what happens. Quote Link to comment Share on other sites More sharing options...
