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

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

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.

      One of the must-haves

      Great sounding compressor with a nice character which can't be found in similar products from other developers. Flexible controls for modern demands are really nice addition.

      YOU guys do the better job! :)

      A. D'Onorio


      Best bus compressor ever!!!!

      Love this one. Really does the job!

      C. Turbin


      Does it well!

      I’d run the demo to try on an album I was mixing and had previously had another plugin G series comp for my rough mixes. I swapped each one in my sessions for this one on demo and was really surprised at how much more punch and drive I got out of it. Later on I was able to get even more out of it using the low sidechain filter and mix knob. Using this as a stereo bus parallel comp is now a new favorite for me. Really helps to give a mix some dynamic control without sounding squashed.

      It's just better than any other Bus Compressor softwere out there!

      It took me a long time to finally purchase the SSL 4000 G Bus Compressor for my UAD plugin collection, but boy did it pay off!

      Before using the UAD version of this plugin, I was using the version of another major plugin software company - but it really doesn't match up to the UAD plugin in any way and I will never go back to the other version again - so I should have just saved my money to buy the UAD plugin much sooner ... ah well ... another lesson learned I guess!

      It's just incredible how well it works. It audibly compresses the mix but without losing any clarity or transparancy and it ads just the perfect amount of saturation, which instantly improves the crest factor of the waveform that is produced when rendering the mix, enabling me to save so much time when mastering my tracks to get that perfect perceived loudness.

      Much , much more important though: It just sounds awesome!

      Put it on and SMILE

      I dont know if it’s just me. But as a person who grew up on the music of early 2000 when I put this one on my stereo bus it automatically gives me the vibe of all the records I grew up on.
      This is one of the 2-3 sterebus compressors that I use nowadays. And I’m not a big fan of compression on master bus. But this one truly ADDS to the song - not just compresses it. I feel 3d vibe and overall a shift in the feel of the record and I love it - definitely adds to the industry professional sound we’re all looking for

      Warm, soft and pretty compressor.

      I use uad's many compressors.
      1176, 175-b, 176, Shadow Hill, LA-2A, Fairchild, SSL, 33609 etc.
      All are very interesting compressors that sound differently.

      The SSL 4000 G Bus Comp is my favorite compressor.

      The reason is that it sticks well in any case.
      The SSL 4000 G Bus Comp does not spoil the original source.

      I also use the legacy version as well.
      It's soft, warm and feels good.

      When recording instruments, I sometimes use the SSL 4000 G Bus Comp instead of an equalizer to create color.

      Be sure to try the 14-day demo and see if it works for you.
      I love G comp
