I just got a used S370 and I am having all sorts of problems with the tuning. In searching this site, I have found two posts that pertain to my problem, but they have not been linked together, and I believe they should be.
http://www.jemsite.com/phpbb/viewtopic.php?t=21569 this covers the issue of having a creaking neck.
http://www.jemsite.com/phpbb/viewtop...t=edge+tremolo and this covers tuning instability. My guitar has a TRS trem

(yes I know they are horrible) but it stays in tune fine, except for when I either dive or pull up there is a creaking noise that comes from my neck. When I push, the tuning goes flat, and when I pull the tuning goes back to normal. I have also noticed that this only occurs when the
locking nut it tightened on the strings, when I have not locked down the nut there is no creaking. Options I have considered include buying a new neck, buying a new locking nut, buying an Edge trem and having my guitar routed, installing a
trem setter or setting my guitar on fire

. If anyone could leave any suggestions as to how I might fix my guitar, it would be greatly appreciated.
