I found this on the VLM-Augustin website. The Vi-Vi electro-acoustic violin is a fusion of wood and carbon fibre and with a Stringamp pickup system.
The design is a quite traditional Chanot shape, which is often seen on carbon fibre violins. But the Vi-Vi has chosen spruce for the top and maple for the neck and scroll.
Later on there should be a cello with the same pickup system.
