Great to see this thead. I bought one of these this last fall and love the guitar . I do play in open tunings mostly and find the Zero fret very very helpful . I have a lot of guitars and this is the only one with a zerro fret but it is an excetioal sound and is always right on the money ! Intonation and tuning are a breeze.
            When I saw Martin Carthy in concert he mentioned that it took some real perswaideing   on his part to get Martin to build the guitar with a zerro fret.   .             I hope you get a chance to play one of these wonderful guitars . I cant remember but I think they said they were going to make 81 units .
               All the best , Guy
