The SSL G Compressor as modeled by Waves.
History of the hardware
The SSL G Bus Compressor debuted in 1987 as part of the SSL 4000 series console, designed to compress an entire stereo bus rather than individual channels. Integrated into the console’s center section, it became a widely used tool for shaping mix dynamics with its VCA-based gain reduction and auto fade function. Later, standalone rack and 500-series versions were introduced, preserving the original circuit design while allowing for more flexible studio setups.
The Plugin
Compare this to a few other SSL G Bus compressors emulations:
Ideas
- The ability to filter the input signal/side chain can help keep the bass strong and can help eliminate unwanted pumping.
- The auto-fade might be true to the hardware, but do your fades manually. Just saying.
- Leave the Analog button off. Standard Waves advice.
- The common master bus setting is a 30ms attack, auto release, and a 4:1 ratio, with the threshold adjusted for about 1-2 dB of gain reduction on the loudest parts. Of course, you can tweak it however you like, but this is the setting people always ask about.
