Does anyone have an easy schematic of a passive eq with fixed bands at say Hi at 12, Low at 80, and a mic dip. Something without an amp section, just caps, resisters, and attenuators?
Thanks Gyraf, and might I say thank you very much for sharing your input and ideas here. I finished one of your SSL's and it is really great.
Any ideas where to find the circuits and any in paticular you like?
You could look through "Technician's filing cabinet" - here:

For a full-passive type you could look into how it's done in tube guitar amplifiers. My favorite simple-eq is the baxandall type, but that takes at least one tube or transistor, as it needs inverting gain to work.
