The Eventide Omnipressor Plug-In Dynamics Processor traces its lineage to 1971, when the Omnipressor® rack unit began showing up on hit records and has left its mark on music throughout the last four decades. One of our first customers was a young Brian May, lead guitarist of Queen. With the Omnipressor in his rig, his sound was never the same again. Professional quality dynamic-modifier for gating, compression, limiting and expansion. The Omnipressor is even capable of reversing a sound’s envelope, making loud sounds quiet and quiet sounds loud.
