I noticed this on a Fender '75 reissue I was playing at the store. And it only seems to happen to maple fingerboards with black blocks. Basically if i run my fingernail across the inlay at the first position I can feel a separation between the block and the surrounding wood. It's very subtle but it's there. How bad is this? I really like the bass and the neck is perfectly straight and I would have bought it outright if it hadn't been for this one issue. Should I stay away?
