I'm moving overseas in December and would like some advice about how I should prepare my basses and acoustic guitars for the move. The packing side isn't an issue as they will be using packing inside the cases to avoid the instruments moving, protective packing on the outside of the case and putting them in the container in such a way as to avoid anything heavy falling on or pushing against them during shipping. Should I loosen strings and ease off the truss rod or just leave everything at pitch? I'm leaning towards leaving them as is (I assume that's the way they get shipped from the factory) but was wondering what others think. Thanks in advance.
