When I have run my preamped guitar through a lag processor the output is
filtered with like a simple 1 pole LPF.
I believe an envelope follower has (at least) full wave rectification since
an AC wave has no DC component. The rectifier, I think, would introduce a DC
component which was directly proportional to the amplitude of the input
signal. Clearly some filtering is needed to smooth out the "HF" stuff, but I
think that would be post rectifier -- note: I haven't looked at a schematic
of an EF in a long time, but I know that a LP will merely filter the audio
like a grainy tone control.
Too early!
