Klanghelm’s MJUC compressor plugin was a very huge success in the latter part of 2015, when it was released. The compressor subforums “exploded” with Gearslutz users talking about how much they loved Tony’s plugin. WIth its ultra low price point, but ultra high sound quality ratio, there isn’t much to dislike about it. The MJUC is effectively three separate variable-mu tube compressors, all with their own unique internal adjustments and sonic characteristics, that span the history of tube compression. MK1 has some of the slowest compression times of the three, has the least amount of controls, and emulates the tube compression sound from the hardware gear around the 1950s. It imparts the most amount of “character” out of the three. MK2 is based around units from the 1960s and offers more control, such as independent attack and release times control, compression ratio choices, a “Density” control that adds another variable mu tube compression stage, and an “iStage” control that engages an interstage transformer. MK3 is the cleanest of the three and offers the most flexibility and gives the user an additional “Punch” control. “Punch” allows more or less of the transient peak through the compressor, regardless of the attack setting, and can add massive amounts of “snap” on percussion instruments. All three makes offer an additional control panel that allow the user to add some saturation to their tracks via the ‘Drive’ parameter and adjust the tonality via the ‘Timbre’ control. Klanghelm’s MJUC has been a major success and has subsequently set the bar extremely high for the competition, as it seems to be redefining what is possible in the world of low-cost emulations.
