I'm looking at a Stage II for a great price for an obvious reason, there is a crack in it. If you look in the photo, it starts at the bridge and goes to the end of the bass above the E string. I've been told this is probably due to not oiling the bass and it looks like it hasn't been dropped. I asked if it was 1/8 in deep and they said well under that. Will this worsen over time? Can it be repaird? I've heard both it can and it can't. And what would you expect to give in this condition?
