The Empirical Labs PUMP is a compact 500 Series compressor with all the clever attitude, control, and musicality you would expect from the makers of the Distressor, Arousor, and Mike-E.

Originally imagined back in 2014, PUMP brings serious ELI heritage into a single-channel module designed for everyday studio use. It is fast, flexible, and full of character, making it a natural choice for vocals, drums, bass, guitars, synths, and anything that needs a bit more shape, punch, or control.

The front panel gives you an input level control with clip indicator, 8 selectable compression ratios from 2:1 to 20:1, and digitally stepped Attack and Release controls for easy recall. The release section also includes a soft opto-style mode for smoother, more relaxed compression.

A switchable 110 Hz high-pass filter helps keep low-end energy from driving the detector too hard, while the AtMod function slows the initial attack response to let more transient detail through. The result is a compressor that can tighten, lift, grab, and enhance without flattening the life out of the source.
