Creaking bass.

[Richard Prowse]

The bloody creak is back! It returned after about an hour and a half of playing. I got my wife to hold the bass and make it creak (pushing on the that L shaped thing at the back of the neck) while I sniffed around. I can tell you that it's definitely not the end pin. It's somewhere in the body. Probably time to consult a local luthier.
