Tone Control Network for ZEN/Aleph based on James-Baxandall's topology

[tiefbassuebertr]

Are there circuits for tone control network, based on James-Baxandall's topology, suited for the Aleph- or ZEN topology without additional line gain stages (i. e. frequency dependend NFB network instead only two resistors)?
Thank you very much for advices.

I think not , due to limited OLG of amps itself
