Passive-Bass
Passive-Bass:
This is a passive EQ with only Bass Boost. One bell and one shelving band only boost. Both 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.
