This pedal was quite a pleasant surprise for me. I was expecting it to be bender-like because the knobs read level and attack. However, I've been using it as my main overdrive now (prior main OD was LP eternity burst). Knobs around one o'clock. I prefer the half open circle which I assume is a mild mid boost- the other two settings full range (shaded circle), and mid-scoop (open circle). I didn't get the fuzz aspect of it, so I tried backing off the attack and loved that sound as an OD. For fuzz I am using a violet ram clone pending getting a skreddy. And for cleanish sustain using a Skreddy Top Fuel, which stacks well with the sic in front.
