* Gain: This knob controls the amount of distortion applied to your guitar signal. Turn it up for more distortion, and down for less.
* Level: This knob controls the overall volume output of the pedal. Turn it up to make the pedal louder, and down to make it quieter.
* Tone: This knob controls the overall tone of the pedal. Turn it up to make the pedal sound brighter, and down to make it sound darker.
* Distortion: This knob controls the type of distortion applied to your guitar signal. There are three different modes: Tube, MOSFET, and Distortion+. The Tube mode produces a warm, natural distortion, the MOSFET mode produces a more modern, aggressive distortion, and the Distortion+ mode produces a more extreme, saturated distortion.
* Contour: This knob controls the mid-range frequencies of the pedal. Turn it up to boost the mid-range, and down to cut the mid-range.
