Mandolins, citterns, bouzouki's, Big, small, hand carved - endless possibilities exist in the mandolin family. So I restrict myself to the larger instruments - octave mandolin, cittern, and
bouzouki with a common body size and variations in string courses and scale length. ( I'll do an F style carved instrument if you ask me nicely ). If you've ever tried to buy a case for a mandolin,
you'll know why I stick to a common body size.
