RG1570L Help needed!

[Valley of Eternity]

Hey, I'm having problems with my RG1570..the guitar is about 4 years old, been my main guitar the entire, have been using it regulary at gigs for the past couple years, never had a problem with it.

Now it will not stay in tune at all, It will tune up, everything locked, started playing and the tuning goes all over the places, usually the D and G got a full step flat, while the E and A go sharp. It does without even using the bar.

I was just playing halfway thru a gig, and it went out of tune..and its been having this problem ever since.

Any ideas on whats going on? worn out knife edges or trem studs?

could be strings are new and slowly stretching as you gig...

Could be that the locking nut is allowing the strings to slip.

Could be that strings are ready to break, unless they're new

Could be that the strings are slipping out of the trem

Could also be that the trem springs are no good anymore, except that it is only two strings, AND a full step.
