Help! MM Majesty G String

[HartDesignsEtc]

I absolutely love my majesty, but I'm having an issue with the G string.
Anytime I use the trem, the G string goes sharp. Other strings stay in tune.
I have tried everything I can think of, but nothing has helped.
Suggestions?

Well, what have you tried? Do you use standard strings, or the RPS style? With the piezo especially, the string can move across the bridge, and sometimes the wrapping on the ball end moves. Having the ball ends reinforced helps prevent that.

The other possibility is usually the nut. In fact that's usually where it happens. Have you tried lubricating the nut?

Are you still using the original string gauge?

I have tried different strings, but the issue remains. I am now back to the slinkys that are recommended for the guitar. I have tried graphite lube on the nut. I am using the original string gauge.
