About the Schertler Group companies
Swiss company Schertler SA was founded in the early 1980s by bassist Stephan Schertler. It quickly established a worldwide reputation for achieving the highest levels of accuracy in the reproduction of acoustic stringed instrument sound. Research and development has focused on producing high-quality contact microphones and acoustic amplification systems. These include the STAT, BASiK and flagship DYN P48 microphone series and the Classic, Deluxe and JAM ranges of compact amplifiers.

Italian company SR Technology (purchased by Schertler in 2012) is dedicated to the development and production of high-quality compact loudspeaker systems. Italian musicality combined with Swiss precision has formed the basis of the famous "SR Sound”; deep, decisive bass complemented by a soft, crisp mid range and perfectly integrated clear “highs”. The goal for all SR products is to combine transparency and musicality in an affordable product range, for live performance, home listening and installation, which does not compromise on sound quality.

The Velvet Strings brand developed from Stephan Scherter’s own interest in building quality strings for double bass that presented an alternative to standard steel ones. Growing demand for the metal covered, synthetic textile fibre strings led to the production of string sets for cello and double bass, with strings for violin, viola and guitar soon to be available.
