Empirical Labs Pump 500 Series Compressor

The Spirit of a Revered Compressor in a 500 Series Package

Need an excellent compressor but you’re short on rack space? You can “de-stress” by purchasing the Empirical Labs Pump 500 Series Compressor! Channeling the spirit of the company's beloved compressor (you know the one), the Pump packs a mighty punch for such a compact size. It’s got an easy-to-read front plate, with knobs for attack, release, input trim, and output make-up gain, plus a continuously variable attack modification (AtMod) knob for shaping transients. There are also buttons for ratio, bypass, and turning on Saturation Mode - which is where Sweetwater really thinks the Pump shines. Colorful LED indicators also clearly relay information about current ratio and gain reduction, and there’s also a 70Hz HPF plus soft clipper functionality that sounds very musical.
