Mastering Comp EQ by Labo ★ K effects


This is the Deluxe version of the Mixbuss SSL4000 compressor. The stereo compressor has all the options/improvements of the famous GSSL compressor.

The design of the electronic boards has been completely redesigned by Labo K Effects.
The switches used are Grayhill switches known for their high quality and durability.
The frequency dosing potentiometers in passive filters such as PULTECH have been replaced by switches in order to provide accurate stereo settings.
A mixing section of the 3 available signals (Direct, post compressor, post equalizer) has been added to refine the processing result.
