Creaking S570 neck
Hi all, I'm newly registered on Jemsite. I have an S570 which is set up correctly in terms of neck relief, action, etc. but it has a weird problem - the neck creaks whenever I use the whammy bar, up or down. From holding the neck, it feels like two or three loud creaks coming from inside at around fret 5. Strange thing is - it ONLY happens when the nut clamps and bolts are tightly in place on the strings. When they are removed and the string tensions run all the way up to the tuning pegs, the creaking doesn't happen (the guitar is properly in tune in both cases). I'm certain the nut is not loose - both fixing screws are tight. The neck is also tight in the body. It seems to me like the truss rod is kind of binding against the inside of the neck. Does this sound even possible? Should it really move? I wouldn't have thought so. Any other ideas what could be and how to fix it? Thanks.
