Re: whats the differance
Well, as far as i know, Overdriving a transistor or a valve circuit will cause clipping and overtones, which we percieve as distortion.
I've never understood it when people discuss the difference between "overdrive" and "distortion", all overdrive will distort the sound in a way. Though, i migth see that the word "distortion" is more commonly thougth of as a more drastic effect than the word "overdrive".
Just my 2kr.
