The Only End-to-End 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, our 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 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.

Great Bus Comresor

Untill now used SSL G Bus Comressor of Wavs plugins.Here we have much more clear sound.... UAD team, this might be the best emulation of the G Bus hardware!

It does the thing.

I was using a competitor's G Bus compressor but became discusted with that company and stopped using their software. This compressor is a suitable upgrade. If you have experience with the SSL Bus compressor sound, you'll recognize it immediately with this. It's instant. Great work! So glad to have this sound again.

my go to

When I want to compress with the 'SSL' style, it's my go-to! I really like the sound of this plugin and the punch it brings to the mix. The 'sidechain' function is also essential! By adjusting this setting, you can really achieve compression that's even more precise and better suited for each mixes. I highly recommend this plugin!

The best bus compressor

From a transient point of view ;-) - the best in my opinion

I have many softw. emulations of G BUS Comp including SSL's one, so I was very eager to check out the native demo from UAD and I am delighted.
I played with the original HW on a large console, but I don't have it. I have one from another company, with digital recall.

I always test compressor plugins on raw acoustic drums recordings, because then you can hear whether the compressor really destroys transients or not.
This one is supposedly quite an old plug-in, but it is gluey and punchy as hell on Mix-Bus and I consider it the best in this (SSL Bus-comp) role at the moment ITB, definitely.
Additionally - it barely touches the CPU.

Doubleplusgood

This is a superb compressor. Very clean non-coloured sound that works excellently with drum material and many other things I've tried. Try a 10ms attack and a very quick release on a 10 ratio - dial it in using threshold and mix control, and adjusting the SC listen frequency. Don't get it to do too much work and it's brilliant on stereo or other busses.

Great price and quality

I cannot believe I managed to buy this for so cheap. It has such a great sound. Over the years I've always wanted to try UAD and now they're native, I can. Thanks UAD for bringing your stuff to us native users, I have a lot of your stuff now and I'm really impressed.

finally in the native version, although I have a UAD card, but in native mode it's super, less load on the card. 10 dollars is not a pity
