> Silicon diodes follow an exponential
Transistors do.
Diodes could, but most commercial product is doped for better performance at the high end, and shows a change-of-slope at the kind of currents we are playing with Bob Pease had a graph.

There was measurably large reverse-current? Curious. I have never seen a reverse current big enough to show up on an ordinary DMM, myself.It matched tbis type of plot:
All my diodes followed that type of curve

A simple transistor stage before diodes to ground has the merit of being able to scale up (or down) the signal to clipping point ratio, and you can do some preshaping of the frequency response there as well.
On Black Ice?
Yes, of course, there was no supply power there, just diodes clipping signal one way or another.
There might even be different diodes to get unsymmetrical clipping.

Uh no, well maybe if you're trying to amplify a signal. There is power in the signal. And the point here is to limit it. But it is better to use powered amplification stage. More control of what is feeding essentially a clamping circuit.
An example of a jfet transistor clamp is putting a gate to the signal line and drain and source to ground. No power other than the signal. The problem here is with the magnetic pickup, or at least the challenge of getting something useful at the output of it. There are no magic solutions, if a 9 volt battery is required, or 200 V plate supply so be it. You could build incredibly sounding circuits out of 3 or 4 transistors for tens of dollars. Op amps that are 2 or 3 dollars each. I don't see the return on investment with a passive clipper based on what their asking price is.
