ok well, i dont want to argue about semantics. So lets call it tube driven eq. The questions still remain

Well, it's not semantics to me there's no active filtering in your schemo beside fixed local NFB.

I was wondering if anyone had expecience with using a cut/boost type EQ where lows/mids and highs are each driven by half of a 12x*7.

would the signal have to hit the 3 filters in parallel? or is it better the have a lows filter that feeds the mids filter that feeds the highs filter? are there any designs out there that do something like that?

thanks

To me it's better to do it parallel. One low pass for the bass. One band pass for teh mids, and one high pass for the trebles. all of that summed in another low pass filter, with a -3db point around 6000hz, may be made variable as a presence. Let say 3000 to 8000hz. JMHO.

Bye.
