Devilfish mod - a well kept secret?

[Rob]

This, too, is true.. FWIW, I have been able to get a very close replica of
the devilfish prefilter distortion merely by replacing the input resistor
with a 150k log pot.. BTW, normally, its just a 100k resistor, but I put a
150k in there cuz when you attenuate the signal going into the filter, this,
too, produces some desirable results such as insanely loud resonance when
compared with the input signal.
