Give power, cohesion, and drive to mixes, buses, or any source

Harness new features like Side Chain Filtering, Mix, and Headroom controls

Mix with artist presets from Just Blaze (Beyoncé, Kendrick Lamar), Peter Mokran (The Flaming Lips, Mary J. Blige), Ian Boxill (Prince, Tupac), and more

The Only End-to-End<br />SSL Bus Compressor Emulation

The Only End-to-End
SSL Bus Compressor Emulation

Embarking on a ground-up re-design of the original SSL G Bus Compressor plug-in, UA’s team of engineers meticulously remodeled every nuance of the in-console and FX G384 rackmount specimens, including their unique CV (control voltage) summing. By capturing all of its circuit behaviors, the new SSL G Bus Compressor plug-in gives you all of the famed SSL hallmarks — punchy, transparent glue, and an ultra-accurate stereo image.

Original Recipe

Original Recipe

From subtle and transparent dynamic control to more aggressive textures with peak limiting, the SSL G Bus Compressor plug-in’s simple, intuitive control set lets you quickly dial in what you need. The fixed Attack and Release controls are SSL-voiced for bus functionality, including the program-dependent Auto Release function. Conjure "barely a wiggle" 2-bus glue, or "bury the needle" full dynamic crush with the continuous Threshold control.

Custom Enhancements

Custom Enhancements

New workflow features make the SSL G Bus Compressor Collection even more vital for the modern producer/engineer. The internal Side Chain Filter allows you precise tailoring of low frequency response to reduce low-end “pumping,” while the Mix control provides inline dry/wet processing — perfect for quick parallel compression on a drum or vocal bus. The Headroom control lets you adjust the overall operating level of the plug‑in.

Fade to Black

Fade to Black

Just like the console units, the new SSL G Bus Compressor features the original Auto Fade feature, providing the signature SSL fade taper, up to 60 seconds. With the new SSL G Bus Compressor, plus the included DSP-lite SSL G Bus Compressor Legacy plug-in, you can craft your projects with Platinum‑selling sound.

      Not so fast

      I own the 500 series ssl g comp and I can attest that it has a way of reducing the width of a mix so I don’t use it as a master bus compressor , but instead use it on stereo sources where I want the stereo width to be less .

      Best SSL G Bus Comp Emulation

      Love UAD for making this plugin a solid beast - sounds better than some other emulations - and does a great job of dialing in with ease. Always use it on my drum bus and sometimes on the master if I am going for the SSL sound - more glue, but with sacrifice on the sides (M/S).

      Amazing plugins

      The SSL 4000 G Bus compressor collection is definitely worth the money. It’s incredible how much cleaner everything sounds now. The waves one is good as well, but you get a much cleaner sound with these! I only have 2 complaints: 1. You can’t view the parameters. 2. The latest updates aren’t compatible with Mojave which is beyond comprehension as a lot of producers still use Mojave and older Mac operating systems so they can use 32 bit plugins and applications. I really hope UAD take this in mind.

      Muy contento con UAD

      Los plugins de UAD, de los que he probado, son buenísimos, y este no podía ser menos. He probado otros, y desde luego UAD en primera posición. Felicidades a los creadores

      Great, but missing one thing

      The compressor is great and I’ve used it on percussion and guitars mainly. Gives a nice natural feel to digital drums. The G comp is also great for mastering. My only gripe with it is that it doesn’t have a sidechain function. Please add one!

      SSL 4000 G Bus Compressor

      This amazing vintage mix bus compressor is just the perfect addition to any instrument in the mix chain, acting gently and really adding that analog compression feeling, can be used almost on any instrument or vocal to make the over all mix tighter and more precise.
