Hello friends,

I just picked up a used sweet Art and Lutherie 12 string, one of the new funky looking ones. When I fret any fret on the G strings, the thin string is way sharp. This only happens with this one string. Happens when I fret with fingers or put on a capo, same thing.

Do I need a setup to take care of this?

Or might a change of strings remedy the problem (the strings are due for a change)?

Or is there another simple fix?

Any input is always appreciated.

Thanks!
