Solid case unlike plasticky Behringer, which is good. Overall hardware is great.
Comes in 6 knobs, 3 band EQ, Level, Voice, Drive. Voice knob, in my personal experience, more like a mid boost but in a certain range. It could be low mid. When you turned that knob up, the whole sounds just get fatter. If you have single coil or bright humbucker guitar, this maybe gonna be your friend.
Now here's the problem. The Voice knob has a double duty. First, it will fattening your overall sounds. Second, the gain will be increased pretty big. I thought this case is happen cause the midrange is boosted at certain db or whatever, the gain will be increased too. Problem is, when you want to clear it up, you may turn the Treble knob up. When it happen, your sound is gonna be harsher. I don't know if I am little too picky, but that's what I hear. Maybe I will do some mod to change the Treble frequency to more pleasent sound.
As many drive pedals, turn the Drive knob full to get chuggy metal will not help because this pedal was designed to be a mild distortion. Think AC/DC, Zeppelin, etc.
Overall, it's nice for the price tag.
