Ubaid, hi again. continuiation of the last thread.
You really need to breadboard these at this point. The schematics you use should all work if you just 'like the concept' of what your doing - that is, replacing the dr. boogey first with cascode, now SRPP stages, etc., first a passive tone stack, now an active tone stack as I suggested... But if you breadboard, you will verify, and better yet hear and compare the differences for yourself. They are starting points for tweaking. But no matter how many times you post, you can't get people to hear for you... I encourage you to start tinkering and listening, then come back knowing what you do and don't like, if you don't know how to get what you do like.
Also, Derringers tone stack is not an active tone stack, it's a buffer, with a passive baxandall, plus a gain recovery stage. That is not active. Since it's passive, the controls are highly interactive. Active tone stacks implement negative feedback and control a frequency range that has little to no interaction with the other tone control(s) unless it is so desired. The 3 band is a good example.
This is the active version of what derringer posted, and one I like a lot, even over the 'classic' active baxandall circuit, since you can actually change caps to boost a different (bass) frequency range than the frequency range you want to cut, if you mod it: http://focus.ti.com/lit/an/sloa042/sloa042.pdf
Not sure how inverting phase and low input impedance are synonymous--maybe you can explain that, head_spaz.
