Gem EQP combines emulations of three legendary passive EQ units—namely the Pultec EQP-1A, MEQ-5, and HLF 3C—into a single plugin that enhances their original tonal qualities with digital flexibility. Each module faithfully recreates the classic analog sound, including the unique harmonic characteristics generated by the original hardware circuits. This plugin features an intuitive frequency response display that provides real-time visual feedback, making it easier to shape your sound with precision. The resizable interface and selectable high oversampling mode ensure that users can tailor the experience to their workflow and maintain high audio fidelity.

The plugin integrates a programmable clipper that adds punch and transient enhancement, expanding on the capabilities of the original analog units. The Low & High module is renowned for its distinctive dual-band boost and attenuation, allowing for deep bass and smooth highs with precise frequency targeting. The Mid module offers multiple boosting and attenuation bands with a fully passive circuit design and transformer-based harmonic coloration, delivering a musical richness to tracks. These features combine to provide a warm, fat, and detailed sound that has made these EQs a staple in professional mixing and recording environments.

Gem EQP goes beyond simple emulation by incorporating an internal calibration system that adjusts the harmonic generation character, offering users control over the tonal color. Undo-redo functionality facilitates experimentation without losing previous settings, promoting creative freedom. Using advanced harmonic matching technology, the plugin captures the essence of the original analog designs, preserving their unique midrange detail and bass warmth while offering modern enhancements. This makes it an essential tool for engineers seeking both classic tone and contemporary control in their mixing sessions.
