I decided to build a clean EQ. Since I don't feel like copying anything too closely I ended up modifying Sontec topology heavily. As everyone knows there are issues with whole range gain and noise performance with different Q-values in the trad circuit. The way around this is sort of easy, but requires quite a lot of components. Q has to be based on chancing caps, not resistors.
Any how, here is my take. OP amps are class A, jfet input and jfet output designs. Very low in noise and distortion.
