Analog Saturation Character and Spectral Drive
Klevgrand describes REAMP as a complex spectral saturation processor. The seven models are based on real analog gear that was measured individually, and the developer says that data is used to transform the input audio into the output.
The four-band spectral drive adds control beyond the selected profile. You can let the unit work harder in specific bands, which is useful when you want saturation concentrated in one part of the spectrum rather than applied evenly across the mix.
The Dry / Wet mix control lets you keep some of the untreated signal, so you can add coloration while preserving the original transient detail.
