The "inverted" charateristics that i was talking about is only valid for the freeback circuitry : it's really re-injecting the signal from the output to the inverting input of the opamp, right-to-left in your schematic.
It not about the signal being inverted, but about some inverted signal being fed to the opamp.
So it should be R7 -> C6 for it to be a LPF (like normal)?

Also, would R7 work with the drive pot to set the gain, or is the drive pot all on it's own?
