I am shipping a bass guitar across the country via Fedex. It does not have a hard case or a gig bag. I have heavy gauge cardboard to construct a box with a neck support to properly fit it and will wrap the entire bass in multiple layers of bubble wrap. The bass will not be able to move around inside the box. I have never shipped without a case before and would like some input if this will be sufficient to make the journey. The bass is worth $800 and will be insured with a signature required from the recipient. Thanks for any suggestions.
