yes got it sorted, not sure what I was doing wrong to be honest, it was the same note open and at the 12th with a tuner but first few frets were sharp, then I redid using the harmonic and it was ok and it's still right open and on the 12th fret, must just be more accurate the harmonic way I guess, but yes if you have to decide it's better to be right on the first 5 frets than down at the dusty end
