FUZZ LAB 03
The Rat is about as perfect of a pedal that you can make. It's true strength is that you going to have it nearly dimed and it will still almost fully clean up by rolling off your volume knob. You have your perfect setting and then you never touch it again.
MORE - Overall gain
HARSH - Cuts high end
ROCK - Ruetz mod changing the overall gain structure. All the way up is the classic full throated rat sound but as you turn it down the gain will decrease but the amount of bass in the signal will increase.
