This pedal can go from a nice raspy boost, all the way up to some really high gain heavy stuff. The GAIN and the TONE knob work great. Very wide sweep for both. I have noticed that the LEVEL knob doesn't seem to be as responsive... but it's not that big of a deal, considering the pedal was $15.
Overall, I'm very happy with it!
maybe its how i play, or what, i play, but i do not find my self confortable with the way it behaves, do not like the kind of distortion it makes and some dials do not control the out put as i wanted to. It´s cheap so it was my first pedal (in the dream of having a large pedal board), but if you want to play to heavy distortion do not use it alone, use it with a fuzz pedal or a compressor pedal and then you will find your self in that yellow brick road in the way to Oz.
