EC Distortion is a simple method of adding asymmetry to guitar distortion. This is a digital effect, which uses direct soft clipping. 8-x over sampling helps to avoid sampling noise at high gain. Distortion is a sound effect which is achieved by distorting signal, especially amplitude clipping. A device or plug-in which does this is also called distortion. It's primarily applicable in hard-rock, metal and punk-rock music, when distorting guitar sound. Often all the effects distorting guitar sound or enriching it with harmonics are called distortion.
