GML, Inc. was founded by George Massenburg in 1982 to produce equipment as needed for specific recording applications. Some early ideas' time had come and were soon realized in GML's products - notably that of 'Parametric Equalization' but also seminal features of third and fourth generation automation systems for recording studios. More recently introduced devices, such as the GML 2032 Mic Pre and Parametric EQ, have been in development, on and off, for 20 years. Currently the company manufactures this, world-renowned Parametric EQ, GML Dynamic Range Controller (with true-RMS detectors, remarkably accurate log converters, and fast peak detectors) and the GML Microphone Preamplifier. GML also consults and provides independent design for several major audio electronics manufacturers.
