This four-string electric instrument was made in the UK by Bridge Violins in 2017. It has a hollow body made from Kevlar and carbon fibre composite giving it a high strength to weight ratio. Designed to provide an easy transition from an acoustic violin to an electric instrument, the resonant hollow body generates a responsive sound more like a traditionally constructed instrument. Its hollow body design allows for low volume practice without the need for headphones or amplifiers, unlike the solid body of other electric instruments. The composite material is highly stable across the temperature and humidity range. This instrument combines modern composite materials with strategic use of wood for parts such as the bridge, neck, endpin and pegs. The violin has Pirastro Tonica strings which have a nylon core. This example is complete with a Sound Choice bow using alternative materials to those traditionally used, and a protective case.
