Okay, sorry but I have to interject...a graphic eq is anything but. What it does is very minor in control. Parametric gives you by frequency control and provides the way to roll out or in any Q you want. Graphic Eq's were devised for people to buy toys for VERY MINOR adjustments to sounds, nothing serious.
Seriously, go play the pedal anywhere you can find it, you'll see it doesn't do a heck of a lot for an electric player.
