This model is about the size of an OM. In fact it fits in an OM case very nicely. The only difference is that this model has more curves. The waist is tighter and the bottom and top are more rounded. It can be had in a 25.5 or a 25 inch string length with either a 14 or 12 fret neck. This particular model is made of African Blackwood, trimmed in Cocobolo with a cedar top.
