Have you ever been tweaking something only to realise that that 
particular control is not active?

I have and I'm pretty sure I'm not alone. That's because I often prefer 
to make changes only after I've heard them in my mind, but sometimes 
that means I anticipate changes rather than hear the actual change. It's 
very difficult to switch between modes of listening sometimes and so 
visual confirmation is a good thing.

What you don't want is visual indicators that change when they aren't 
actually having any effect, like a graphic EQ envelope when the EQ is in 
fact in by-pass mode.

Don't you mean valve (predominantly even-order harmonics due to the 
softer saturation) versus transistor clipping (the result approaching a 
square wave is predominantly odd-order harmonics - a square wave is only 
composed of odd-order harmonics). Both are analog.

Digital clipping is like transistor clipping. We prefer the even-order 
harmonics over the odd-order harmonics.
