I just bought one used 57 AV Precision bass 1982 made in Fullerton. This body has weird bump area (red marked) IS this kinda collectible shape ? or just one of error ? And I don't think this is original hardcase this this bass, but looks so old, too. I have seen some cases like this during 80s. When is the period on this case ? The embeded Fender logos are on Both side, Top and Bottom.
