61 Standard SG. While conditioning the fretboard, I noticed that the board is raised higher than the binding rather than being even/level with it. This only is the case in a couple spots, as you can see around frets 2/3, then flattens out as you go up. Does anyone know what causes this? Is it normal? Is it an issue? There is a hair that looks like a crack up around 4, I had to go back and check after I saw it in the picture. No issue there. Thanks!
