All MASELEC products are developed by Leif Mases.
His experience as a producer, recording engineer and studio owner,
working with Jeff Beck, Led Zeppelin, Black Sabbath, ABBA and others,
is reflected in the operation and performance of his designs.
Leif has developed a comprehensive range of extremely high-quality analogue processors
that offer precision, transparency and in some cases,
Almost all the rotary controls are switches, not detented potentiometers, so offer great accuracy and repeatability which is essential in mastering for stereo work and recalls.
