From the developer:
The Tube-Emulator section has the unique option of being able to switch between two different sounding tube options from Single-Triode to Dual-Triode. The independent Amount and Color controls permit overdrive of the Tube-Emulator stage to vary the harmonic content of the signal. The Gate/Expander section tames the noise floor so that you hear only the audio you want to keep.
