This is due to the use of fan bracing (similar to that found on European guitars - Hagstroms, Levins, Bjartons from Sweden, and older Hofners from Germany) which gives it an open, loud, direct tone with lots of guts and sustain. The tone on this one, however, is far better than the ladder- braced LG- 0s which tend to destroy themselves over time.
It's essentially the same size and has a similar feel in the lap to a Gibson B- 2.
