I don't see a lot of people using them.
I cannot live without my DIY one i'm using for my subwoofer. For the subwoofer I kept it simple with variable Q which works ok.
I am itchy to design and build a EQ only device for higher frequency to use in stereo setup.
That will have 3 or possibly 4 frequency options and settable Q and gain or cut.
I could even add the ever debateable "bass and treble" tone control with defeat option for extra play.
Call it a complete preamp with 3 selecteable inputs and tone control and 3 parametric eq's
Something like this:
I have a few pcb's the could be used. or most probably lay out new pcb.
There are one chip digital solution , but the thought of taking an analog signal digitizing it and then EQ and than making it analog again makes me feel a bit iffy.
One can simply use quality opamps opa2134's or even ne5532's in a circuit as shown here with small modifications for testable Q:

Is there other people interested interested in something like this? Not really looking to do a group buy. But always cheaper like with some of my other projects if I built a few extra and have people buying extra pcb's and or enclosures of me.
I keep on wanting to use digital pots and possibly lcd screen setup , but then get right back to rather using quality analog smd and simple panel mount potentiometers.
