EPFM Frequency Booster: similarities to EMG SPC and Demeter Fat Control?

[Carlos]

Hi everybody,

I wonder if there are any similarities between Andertons Frequency Booster , the EMG SPC presence control and the Demeter Fat Control.
Has anybody seen the schematics?

Regards

I've heard that the EMG is the Anderton (subject of course to the cap value choice). But that is all hearsay.
