I know what your thinking.. can one knob really make this pedal useful? YES.. you only need one knob. This pedal was one of the biggest tone surprises of my long history with guitar gear. It plain flat out kills. Plus it has a ton of different tones depending on where you set the knob. Yes, the output level is set, but if you set your amp correctly it will not be an issue. Give this thing a try, it will really make you rethink your fuzz pedal game.
