Kontaktiere unsEmpirical Labs EL-P Pump Vertical — a single-channel 500 series VCA compressor with a vertical faceplate, featuring 8 compression ratios and the unique AtMod function.
PUMP is aimed at engineers looking for a compressor sharing DNA with the legendary Distressor, in a more accessible single-slot 500 series format. The module draws on the heritage of the Distressor, Arousor, and Mike-E, offering germanium-diode-based saturation and an attack-envelope shaping feature previously available only in the Arousor plugin.
Preserving Transients Without Sacrificing Compression Density
The usual trade-off with aggressive compression is losing an instrument's attack — a hard-squeezed snare or bass loses its initial click or thump, even if the rest of the signal sounds dense and controlled. AtMod (Attack Modification) solves this by slowing the initial slope of the attack envelope, letting more transient content back into the signal without giving up the intended compression level. That lets an engineer get a heavily compressed snare that still has a clear stick attack, or a thick bass that keeps its finger pluck intact.
Eight Compression Characters in One Module
Working across different sources — vocals, bass guitar, drums — a single fixed compression ratio rarely fits everything, and switching between separate processors slows a session down. PUMP offers eight selectable compression ratios from 2:1 to 20:1, each with its own unique curve, allowing a gentle touch for vocals or an aggressive squeeze for drums without leaving a single module. A switchable high-pass filter on the detector prevents low frequencies from unnecessarily driving compression.
