On/off button: Enable/disable the filter effect.
Type pop-up menu: Choose a filter characteristic. Each option provides a different tonal color and response to the Cutoff and Res control values.
Note: The chosen filter type can alter the names and functions of the default Cutoff and Res knobs.
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. Very high Res values cause the filter to begin oscillating at the cutoff frequency. This self-oscillation occurs before you reach the maximum resonance value.
Mix knob and field: Set the level of the original versus filtered signal.
The distortion unit can add color and a saturated tone to your parts.
On/off button: Enable/disable the distortion effect.
Exciter knob and field: Set the amount of excitation. Exciter generates high frequency components that are not part of the original signal by introducing a nonlinear distortion.
Dirt knob and field: Set the amount of this saturated, gritty distortion characteristic.
A simple reverb unit that can add space to your parts.
On/off button: Enable/disable the reverb effect.
Type pop-up menu: Choose a reverb characteristic. Each option provides a different tonal color and response.
Time knob and field: Set the length of the reverb tail.
Mix knob and field: Set the level of the original versus reverb signal.
