DISTORTION Knob
TONE Knob
This knob controls the tone of the distortion
sounds. Rotating the knob clockwise cuts
lower frequencies, creating sharp sounds.
Rotating the knob counterclockwise cuts
higher frequencies, creating softer, warmer
sounds.
DISTORTION Knob
This knob controls the depth of distortion
sounds and the length of sustained sounds.
Rotating the knob clockwise creates deeper
distortion and a longer sustain time.
LEVEL Knob
This knob adjusts the level of the effect
sounds. Set the knob so there is no volume
difference between the effect and straight
guitar sounds.
