Wah Section
 Wah Mode pop-up menu: Choose one of the six modes, which emulate various classic
wah effects and filter types, or choose off.
 Auto Gain button: The wah effect can cause the output level to vary widely. Turning
Auto Gain On compensates for this tendency, and keeps the output signal within a
more stable range.
 Wah Level knob: Sets the amount of the wah-filtered signal.
 Relative Q slider: Adjusts the sharpness of the wah sweep by raising or lowering the
filter peak. A setting of 0 (zero) retains the original peak level for each mode.
 Pedal Range slider: Sets the sweep range of the wah filter controlled using a MIDI
foot pedal, letting you compensate for the difference in mechanical range between a
MIDI foot pedal and a classic wah pedal.
You can set the upper and lower limits of the range independently by dragging the
left and right edges of the Pedal Range slider, or move the entire range at once by
dragging the center section of the slider.
AutoWah Section
 Depth knob: Sets the depth of the autowah effect.
 Attack knob: Sets the time it takes for the wah filter to fully open.
 Release knob: Sets the time it takes for the wah filter to close.
Fuzz Section
 Comp (Compression) Ratio knob: Sets the compression ratio of the integrated
compressor.
 Fuzz Gain knob: Sets the level of distortion for the fuzz effect between 0 dB and
20 dB.
 Fuzz Tone knob: Adjusts the tone of the fuzz effect between 2 kHz and 20 kHz.

Using the Fuzz-Wah
The following sections cover various aspects of the Fuzz-Wah parameters.
Setting the Wah Level With Auto Gain
The wah effect can cause the output level to vary widely. Turning Auto Gain on
compensates for this tendency, and keeps the output signal within a more stable
range.
To hear the difference Auto Gain can make:
1 Switch Auto Gain to on.
2 Raise the effect level to a value just below the mixer’s clipping limit.
