This model is designed for violinists. Based on my Strad "Kruse" model. It is very slightly wider, and with higher ribs and 4 mm extra body length. It has a functioning violin C string. I've tried to keep as much of the character of a normal violin as possible, but as it is very slightly larger and longer it does tend towards a more "viola-ish" sweeter sound.
Body length of 359mm string length 328mm
