Unless the signal is very hard clipped I don't see how this effect is washed out of the signal.

That is state there, but the problem with this to-avoid-type-of-distortion is something like the crossover distortion. You don't like when playing clean but it actually sounds good with distortion.

:(

> I state it again: Such output waveforms coming out from a generic guitar amplifier are extremely rare and designer's try to avoid such distortions. Probably because they don't sound all that nice.

As you said, tone preferences are a matter of taste. Probably?
