Behind its unconventional and flashy appearance lies a series of boosted upward compressors meticulously designed to include the specific nuances and colors of vintage analog devices. The plugin can operate on either one or three frequency bands and provides a couple of filter slopes ranging from a subtle and transparent 6dB to an impressive 192dB! The workflow is optimized for simplicity and intuitiveness, enabling effortless transitions between subtle adjustments and complete alterations with its up to 120dB of upwards compression.

Whether acting on the entire signal or individual frequency bands, this circuit can transform your sound, expanding your creative possibilities.
