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 has an easy-to-read front plate, with knobs for Attack, Release, Input trim, and Output makeup gain, plus a continuously variable attack modification (AtMod) knob for shaping transients. There are buttons for Ratio, Bypass, and turning on Saturation mode, which is where Sweetwater thinks the Pump shines. Colorful LED indicators clearly relay information about current ratio and gain reduction, and there’s also a 110Hz highpass filter plus soft clipper functionality that sounds musical.
