FAQ
SHI is a frequency-dependent saturation plug-in. It is built for creative tone shaping, adding excitement and weight into incoming signals without overwhelming the whole spectrum.
SHI lets you choose where in the frequency range the saturation is focused, then dial in the intensity and amount. That means you can add low-end weight, midrange body, or top-end edge with much more intent than a broad full-range saturator.
