We're also moving from simple and concise to circuitous and verbose:

"Distortion effects generally mean both soft and hard clipping, and distortion is caused by perfectly flattened peaks due to saturation or cutoff inside a transistor based unit that does not attempt to smooth the clipping of peaks, will be called a distortion pedal, as the transistor responds to changes in voltage quicker than a tube can, while overdrive pedals, usually consisting of transistor based "Overdrive" pedals exist, in which an attempt at emulating "Tube-like Distortion" is made through extensive electronics and IC design, will retain their typical sine wave form, but will be compressed such that there is less difference between the RMS and the peak of a wave. Overdrive units created with transistors, much like tube amps, produce "clean" sounds at quieter volumes and distorted "warm" sounds at louder volumes, compared to the "harsh" or "gritty" sound of simple transistor distortion."

It's going to take me a while to make sense of this.
