i haven't used this pedal, but I've used a lot of parametric EQs over the years (pro audio background here).
If you're looking for the "frownie face" eq, set the highs and lows flat, then boost the mids using the widest "Q" possible, then sweep the frequency knob until it sounds the way you want it. Often exaggerating the settings at first is useful - i.e. Q and Level all the way up before you sweep the mids, then once you find the frequency you want boosted, lower the level to something that doesn't cause instant feedback
