Not just "3-band para", which could have as few as six knobs, if you stretch the definition (more properly called 'semi-parametric') -- but such poster says "TRUE 3-band", which is clearly specifying that the EQ section must have NINE controls.
Let's PLEASE be careful, friends! This forum is highly respected around the world - lets appreciate that, and be careful and thoughtful with specs, and other "facts".
Thanks -

Yeah, I think a lot of people think an EQ knob is a "parameter" (well, it is...) and therefore three band EQ would be three band "parametric", which of course it is not.
I think the confusion is knobs vs. sliders. Sliders are considered a "graphic" EQ, so knobs must be the other one (parametric), and that's not quite the case. When you start digging further into EQ's, it's not just variable frequencies and band widths, but also shapes (shelving, band pass, etc.)
This, my friends, is called "fun with freqs"!
