buzzing on third string

[excalibrate]

my sl1 buzzes only on the 3rd string .fretted and open ,any suggestions to what might cause this?

The only thing I can think of is that the string is not seated right in the saddle. I would cut a little piece off the end of the string and re-seat it.

I had buzzing G strings as well. They akways have been seated too low at the nut end of the guitar. My two cents.
