Of course, high gain amps have from four to six gain stages (and the stages may have attenuation). I’m simplifying by putting all the gain in one stage, but the point is that when you’re cranked on one of these amps, you can count on being locked into the hard-clip region of the curve, and the soft clip region might as well not be there.
