G Bus Compressor



The SSL 4000 G Series bus compressor has been copied, emulated, reworked, and rehashed by both hardware and software manufacturers for years now. It seems every plug-in developer has their own take on the stereo compressor, and I’d bet most readers have at least one in their library. SSL 4000 G Bus Compressor. This is a must have! It just works, easy to use, brings your mixes into focus in just the right way. Except from limited bandwith (problematic at higher samplerates - quite useless as master compressor) a real workhorse. Often very simple units a buss compressors job is to 'glue' all the elements of a track together and make mixes sound bigger with more punch and character without loosing clarity. Features: Analogue Modelled Buss Compressor. The XStudioToolz Stereo Buss Compressor can be used on the Master Buss and also on sub-groups (Drum Groups etc). Integral to the hit-making SSL sound, the G Bus Compressor is legend for making mixes bigger, more powerful, and punchy, all the while enhancing cohesion.

Possible Modifications:

  • Turbo Mod
    • Changes the sidechain from summed (mono) to stereo. This makes the GSSL behave more like the original SSL.
  • CRC Filter Mod
    • Fixes power hum problems inherent in the original GSSL design.
  • VU Meter Mod
    • Usually GSSL builders use a peak meter. The VU meter makes the “feel” of the compressor closer to, say, the 1176.
  • Super Sidechain
    • Adds adjustable 60, 90, 130 & 200hz high-pass filters, Tilt-Medium and Tilt-Loud sidechain eq curves, and the option for an external sidechain input.
  • Crush’n’Blend
    • Adds wet/dry mix control
