Cutoff knob and field: Set the cutoff frequency for the filter. Higher frequencies are
attenuated and lower frequencies are allowed to pass in a lowpass (LP) filter. The
reverse is true in a highpass (HP) filter. When in a bandpass (BP) mode, cutoff
determines the center frequency of the band that is allowed to pass. The comb
and other filter types change the names and behaviors of the filter controls.
Res knob and field: Boost or cut signals in the frequency band that surrounds the
cutoff frequency.
Drive knob and field: Overdrive the filter. This can lead to intense distortions,
depending on filter type.
Mix knob and field: Set the level of the original versus filtered signal.
Distortion parameters
The three distortion units can be used independently or combined to create a huge variety
of tones.
On/off button: Enable/disable the distortion effect module.
Amount knobs and fields: Set the level for each of the three distortion units.
Type pop-up menus: Choose a distortion characteristic for effect unit 1, 2, or 3. Each

to doubling or ensemble type processing.
On/off button: Enable/disable the Mod FX unit.
Mix knob and field: Set the level of the original versus modulated signal. This is a
modulation amount control.
Rate knob and field: Set the speed of the modulation effect.
Type pop-up menu: Choose a modulation characteristic. Each option provides a
different tonal color and effect depth.

Bass Enhancer boosts the signal around a defined frequency.
On/off button: Enable/disable the bass enhancer effect.
Amount knob and field: Set the level of the effect signal.
Tune knob and field: Set the center frequency for bass enhancement. Signals
surrounding this frequency are boosted.
Type pop-up menu: Choose a bass enhancement characteristic. Each option provides a
different tonal color and response.
