Well...the TSC is passive and the SansAmp is active (it's in the NFB loop of the opamp).  They achieve the same thing but they work differently.

Are you trying for an active of passive tonestack?

Many opamp datasheets list an active Bax circuit and they show you the calculations to make your own.
