Egon Rauscher has been hand-building electric guitars since the late 1990s under the brand name Soultool. Soultool is based in Buttikon, Switzerland. Initially Rauscher offered two models based on the Fender Stratocaster and Telecaster, but circa 2019 Soultool's designs are original, beautifully made using certified hardwoods and the best hardware and electronics.
