This adjusts the amount of distortion. Rotating it clockwise increases the effect, whereas counterclockwise rotation reduces the effect.
7. LEVEL Knob
This knob adjusts the level of the effect sounds.
11. GAIN BOOST Knob
Adds even more distortion, in addition to that obtained with the DIST knob setting. The further clockwise you turn the knob, the more powerful the distortion gets, creating sounds that are really expansive.
8. BOTTOM Knob
Adjusts the amount of boost in the low end. The lower frequencies are emphasized more as the knob is turned clockwise.
