$69 at KVR Marketplace (down from $99), 30% off. Sale runs through May 25, 2026.

What it is

The UADx SSL 4000 G Bus Compressor is a fully SSL-endorsed circuit emulation of the hardware bus compressor found in the classic SSL 4000 console. It delivers the transparent punch and mix glue that has made this compressor a fixture on professional mix buses for decades - from barely-there leveling to assertive peak control.

Who it''s for

Mix engineers who rely on bus compression to hold a mix together. Works equally well as the final glue on a stereo bus, on drum groups, or on individual channels that need controlled dynamics without coloration.

Key features

• Side chain high-pass filtering lets you tame low-end pumping on bass-heavy mixes
• The Mix control makes inline parallel compression straightforward without routing gymnastics
• Auto Release mode uses program-dependent timing optimized specifically for bus work
• An Auto Fade function replicates the classic SSL fade taper up to 60 seconds
