In the U.S. nomenclature this would be called a “Grand Auditorium” guitar.   Slightly wider than the regular 14 fret 000 or OM guitars, I designed this to take full advantage of the tonal potential of the woods I use and at the same time to be comfortable to play seated with its tighter waist than most large guitars.  Varieties of spruce tops and rosewood back and sides make this a rich but focused guitar, great for fingerstyle and open tunings.  I also use Australian Acacia and West Australian Jarrah back and sides for different tonal emphasis.
