I'm going to be working on my bass and in the process it will be taken apart and stay apart for at least two weeks. What should I do with neck while it's off the bass for a while? Should I loosen the truss rod to keep it straight without string tension? Or should I even concern myself with that? Just curious. I've done it both ways. The neck is really nice and perfect on my bass and I want to make sure it stays that way. Thanks.
