I've owned this pedal on and off for years. This recent time the pedal has been a total blast. I set the bias slightly hotter than the internal marking for a touch of bite. Having four external knobs is fantastic; something that I got very used to with my old Sun Face and Sun Lion. I REALLY love the Sun Face but damn you can't beat this pedal for < $150. I play P90s a lot and love the tweakability with the input gain knob on pedals like this.
