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.

      Oddly essential

      I don’t have any idea why this sounds better than other SSL G Bus plugs. But it does, and it makes me happy to start a new project with this on my mix bus.

      very frustrated!!!! I had to check a star to be able to send this, but I wouldn't give any stars!!!

      I bought the 4K buss, but it never loaded in properly. I was only allowed the demo version. I had AM/Ex cancel my order and reordered it. And yet, the same glitch happened.

      The Best Bus Compressor tool available on the market

      The SSL G Bus Compressor is the best bus compressor plugin available, hands down. I compared it carefully for several days, against: Logic's compressors, FabFilter C-2, Vertigo VS, DC1A3, RoughRider, NI Solid Bus, and others. The SSL G blows the competition away.

      SSL 4000 G Bus Compressor系のものは数も多く色々試すことになるのですが結局UADの物が一番簡単迅速に求めるサウンドになると思います。デモ使用する度に迷っていましたが、やっとUAD版の素晴らしさが解りました。

      Immediate satisfaction

      I am a budding mixer and need all the help I can get. The SSL 4000 G is the most useful mixing tool I have purchased. Other bus comps, even classics, can be more colourful than I would like. This glues and tames my mixes in a way that eases my mind. Too good.

      The Glue

      The simplest of plugins but provides the glue that tied all my acoustic recordings together providing the best sound I’ve ever had.

      It has a home on my mix bus.

      It is my go to mix bus compressor. Not only does it have a wide color palette of subtle to PUNCH!, but the mix knob and SC filter make it a great and versatile glue.

      Must have

      Big difference between the legacy and this version. The selling point was the side chain knob.

      SSL G-bus kicks some serious a**!!!

      Having no real experience from its hardware equivalent, I am sincerely impressed by this plug-ins ability to add warmth and character on my mix bus and, in doing so, glueing together my mixes in an organic and natural way. I am sure it is pretty close to the real deal, and strongly recommend it! (The sidechain filter is btw one very strong argument for getting the uad version, as you don't have to loose any of the bottom end punch when using it on drums for example.)

      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.
