Get the Ultimate “Glue” for your Mix Bus

Integral to the hit-making SSL sound, the G Bus Compressor is legend for making mixes bigger, more powerful, and punchy, all the while enhancing cohesion and clarity. Fully endorsed by Solid State Logic, the SSL 4000 G Bus Compressor Collection is an expert end-to-end circuit emulation that goes further than UA’s original standard-defining SSL G Bus Compressor plug-in.

Cook with the 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 gives you what you need, quickly. 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.

Work Efficiently with Custom Controls

Use the internal Side Chain Filter for precise tailoring of low-frequency response to reduce low-end “pumping,” and the Mix control for easy 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.

Add Professional Fades

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, you can craft your projects with Platinum‑selling sound.

What They Say

The new SSL G Bus Compressor is expertly modeled with useful enhancements. It’s my go-to punchy drum compressor.
