B. Andrew Barta launched Tech 21 in midtown Manhattan and introduced his unique invention to the world -- the SansAmp. It was, in fact, the culmination of something he simply wanted for his own personal use. As a performing musician with an electronics background, and whose “day job” was repairing, modifying and customizing amplifiers. Ironically, Andrew never intended on becoming a manufacturer and today Tech 21 is one of the leading manufacturers of guitar and bass effect pedals, amps, and DI boxes.
