SCHEMATIC: TL082 9V Active EQ…

an experimental EQ circuit based of the TL082 datasheet. i modified it to use a 9V battery, but could probably still use some work in terms of efficiency… as most things. nothing is ever finished really. the mid portion has a pretty high quiescence. fine tuning, of course, can be done with the resistor values and more dramatic differences by adjusting the cap values. if you happen to build it, shoot me an email and let me know what you changed or decided to change.

also keep in mind that the TL082 is a little noisy, so 6dB of highs will add in some noise. i kind of like it myself, but the TL072 is a better choice from what i understand.
