I have taken a photo and made a few short videos to show the rattles in the strings, mostly the high E.

I have raised the saddle on the low E side a bit but could maybe go a little more if necessary.

The photo doesn't show too much

I can take more if necessary.

Hopefully these clips help (sorry about the face I plulled, playing doesn't come naturally to me )

Do I need to replace the nut or should I try the baking soda trick?

Thanks all.
