Open G string buzz

[Thoraby]

The open G on my Nightswan buzzes. It's almost like a SITAR kinda buzzy sound. I DAFS but I didn't find anything useful(found some folks with the same problem, but noone had presented a solution.)

It's a OFR R1 nut. Anyone got any ideas?

Re: Open G string buzz

ChukSplatter told me you can get shims for this problem (I have it also on one of mine, but it's minor)
I think individual ones for each string PM him.
