3-way active EQ control

[Geiri]

Hey guys! I'm in need of a three way active EQ. I've posted with this a schematic for a fairly simple one. I think it's a Baxandall variation. I'd love for someone to make a fairly neat and nice vero for it and any other EQ that is useful for a distortion pedal.



Oh and please make it just a standard 9V single supply instead of a dual supply.

Cheers!
