Hey,

I have a problem with my Fender FR50 resonator, none of the 13th frets work!

When I try and fret them, I'm met with either a horrible out-of-tune buzz, or the same note as I would get on the 14th fret.

The rest of the neck plays fine.

Is this a truss rod problem?

EDIT: This is also a recent problem, It never used to do this.

ya check your trust rod. umm my friend had a problem like that. he left is instrument out in a cold area and then brought it into a warm area repeatly and the neck of his guitar warped.

sounds like your 14th fret might have come a little loose also. before you mess with the truss rod, try tapping the 14th fret down a little.
