Passive-Mid:
This is a passive EQ with two Boost bands and one cut band. The curves are very broad.
All three bands are based on custom-made Inductors with an discret OpAmp for the gain.
There are two options for the discret OpAmp. The first is a more modern designe and the second is
a more vintage, very simple designe with much more harmonics.
