This FX machine simulates the process of tape saturation/valve distortion. Unlike harsh, digital clipping there is a smooth transition from pure signal to distortion that creates even-numbered harmonics. This makes the sound "warmer", rather than harsh (the odd-numbered harmonics created by straight clipping).

This machine attempts to simulate this saturation effect, and can provide a range of smooth overdrive effects as well as (at lower intensity settings) adding warmth and "creaminess" to the sound - just like tape or a valve.

Threshold: Sets the processing depth. A value of 32768 means none of the wave is processed, and a value of 1 means the whole wave is processed.

Intensity: Sets the Clipping type. A value of 1 creates smooth clipping, whereas a value of 100 will create hard clipping.
