The practical problem here is that the only way to achieve this sound is to crank up the guitar amplifier's volume to ten 2 and live with the attendant high loudness level. That is, the greater the input signal is above the clip point, the more current that will flow, and thus the dynamic resistance decreases, strengthening the effect of the voltage divider.
