GAIN Knob
HIGH EQ Knob
Use this knob to boost or cut higher frequencies;
clockwise rotation boosts the higher frequencies.
LOW EQ Knob
Use this knob to boost or cut lower frequencies;
clockwise rotation boosts the lower frequencies.
BALANCE Knob
This knob controls the output balance between
Dry (straight) and Overdrive sounds.
Counterclockwise rotation increases the Dry
sound, while clockwise rotation increases the
level of Overdrive sounds. When rotated fully
counterclockwise (or clockwise), only the Dry (or
Overdrive) sound will be obtained.
GAIN Knob
This knob adjusts the gain of the Dry or Overdrive
sound. When you are using Dry sounds, this knob
can adjust the amount of boost without distorting
the sound. When you are using Overdrive sounds,
the GAIN knob adjusts the depth of the distortion.
Clockwise rotation increases the gain.
