Stephan Schertler founded his company in the 1986 specialising in audio transducers. Scherler was a double bass player who was inspired to made his own amplification system due to the lack of suitable equipment. By 2000 there were 10 people working in the company and they had developed a range of transducers as well as loudspeakers and amplifiers. Schertler entered the Pro Audio world in 2016 with a new analog modular mixer. There were Schertler guitars made from around 2006 and designed by Claudio Pagelli. The vision was to create a smaller sized electro-acoustic guitar for the stage, equipped with a reference quality Schertler Dual Source pickup system.
