It sounds pretty obvious but I want to know if strings naturally "die out" over even without them being played. I just picked up a new bass and the previous owner said that the strings that are on it (DR low riders) were put on maybe three years ago after a few hours of playing it was tucked into his closest and it had been there until he sold it to me. I know the best way to judge would be by the tone and by that alone these sound dead. But, they look pristine, as if they hadn't been touched. Can they really be dead if they haven't been played on for more than a few hours... 3 years ago?
