Since its foundation in the early 1980s, Schertler SA has launched a program of passionate research that aims to achieve the highest levels of accuracy in the reproduction of acoustic stringed instrument sound. Led by bassist and founder Stephan Schertler, the research and development company initially began to focus on producing high quality tools and innovative technology to replace the technology and imperfections of piezo pickups
In 2003, Schertler launched an original series of compact amplifiers – the Classic Series. Since then, the 3-channel UNICO and 2-channel DAVID have provided musicians with high quality portable solutions for stringed instrument amplification. Suited to virtually any live performance situation, these amplifiers have received unanimous feedback from users around the world, helping to build the reputation that Schertler has gained in the field of acoustic amplification.
