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.
So why does it need knobs?
TRUST YOURSELF to go to tone Valhalla. This pedal will ship stock to my perfect settings, Loud and More at 3:00 and Harsh at 9:00. Feel free to open up the pedal and set it to your ideal settings.
