This is one of my smaller bodied octave mandolins. I make them in a variety of scale lengths to suit the customer. But these largely fall into either 20.75″ or 22.75″. Depending on your style of play the shorter octave mandolins can be easier on the fingers for melody playing. For a lot of players moving over from a standard mandolin you wont even have to change your fingering.
But its horses for courses. If you were after something a little louder and more strident I would suggest the longer scale and larger body.
