Masterful Stereo Bus Compression

Great-sounding stereo bus compression is a must-have. It pumps up your mixes, giving them the glue, punch, weight, authority, and slam factor to stand out from other tracks being broadcast or streamed. If most other engineers are using it (trust us: they are) and you're not, your mix (no matter how good) will sound weak in comparison. So Sweetwater's advice is to have the best-sounding, most versatile bus compressor you can find strapped across your stereo mix bus. Enter the Serpent SB4001 500 Series stereo bus compressor.

Delivers whatever sound you're after

The Serpent SB4001 raises the bar for the 500 Series stereo bus compression. With its Quad VCAs, six ratios, 10 attack times, highpass/boost/slope sidechain filters, Wet/Dry Blend control, external (key) input, classic stepped release settings, classic (A1) and alternate (A2) auto release, and variable Release control, as well as Grind mode (a proprietary tube-style harmonic drive that adds vintage coloration), the SB4001 can deliver whatever sound you're after. Whether clean, dirty, vintage, subtle, or crushed, the SB4001 is sure to be one of the most flexible compressors in your arsenal.

Better than SSL

I love the Wet/Dry parallel compression feature. One of the few 2 slot true stereo compressors out there. Love it
Rated 5/5

Amazing compressor!

I absolutely love this thing. It performs amazing as a buss compressor and for anything you throw at it. This thing can be very transparent or warm depending on how you use it. The wet knob Is wonderful for parallel compression. I use it on everything!!!
