ART (Applied Research and Techology) was founded in 1984 in Rochester, New York by former employees of MXR (the original MXR Phase 90, the original MXR Flanger (the Eddie Van Halen sound) and  the MXR 175 Rackmount Delay as used by Eric Johnson were created by an ART Engineer). The ART product line began with a primary focus on pro audio processing and consisted of rack mounted, high-definition equalizers and digital reverbs. The ART range also included sepcialised guitar and bass digital signal processors and rack mounted effects. Currently ART specialises in vacuum tube preamplifiers and compressors, graphic equalizers and various other useful audio tools designed for stage and studio.
