T-BASS on older Aiwa

Hello,
Did anyone found a way to diy circuit for T-BASS that is found on some older Aiwa systems?
I will be making an amplifier soon (waiting for the parts )and I was thinking of adding T-BASS function to it if this is possible?
Traditional bass boost on low end devices sounds terrible to me, so does bass boost function on sony recievers (i can`t remember what is it called) and some other brands.
But T-BASS sounds really good to me, so if possible I would like to build this circuit 🙂

Thank you for help
