I LOVE THIS PEDAL!!! I adjust the four graphic equalizer setting controls and the distortion level and it produces a massive array of distortion tones. Once I dialed in the searing distortion sound I was looking for I was in HEAVY METAL HEAVEN! I leave my amp settings at 12 on clean and use my pedal to adjust my distortion tone. Also, if you don't know where to start, the pedal comes with diagram setting for different types of music to get you started. As always, start the controls at 12 o' clock and move them. There are hundreds of distortion pedals out there, mostly with 2 or 3 knob controls, this pedal has 6. Four of those knob controls are stacked on top of each other. The guitar players who don't like this pedal are the ones who don't want to take the time to learn how to use this pedal properly and they give up, blaming the pedal, when in fact the guitarist needs to learn how to adjust the pedal. If you buy this pedal as I did, it gives tons of different distortion tones and you'll never have to buy another distortion pedal.
