On December 27, 1967 Doug Sax opened the doors to The Mastering Lab Hollywood, founding one of the first independent facilities in the world, as well as the most recognizable name in mastering. Now located in Ojai California, The Mastering Lab remains a revolutionary state-of-the-art company, utilizing unique concepts of signal flow and electronics pioneered by Doug's brother, Sherwood Sax. Indeed all of our custom-electronics from the tape machines to the equalizers, compressors / limiters, A/D - D/A converters, monitoring amplifiers, and console are all purpose designed and handcrafted. The musical use of this peerless equipment has earned The Mastering Lab more Grammy nominations for engineering than any other mastering facility.
