It cuts the specified frequencies and adds distortion.
Parameter  | Value  | Explanation  | 
|---|---|---|
CUTOFF  | 20–16000 (Hz)  | Sets the cutoff frequency range in which the filter works.  | 
RESONANCE  | 0–100  | Adjusts the filter’s resonance level. The larger the value, the more that the frequency range set in CUTOFF is emphasized.  | 
DRIVE  | 0–100  | Adds distortion.  | 
FLT TYPE  | Sets the type of filter.  | |
HPF  | Cuts off the low frequencies.  | |
LPF  | Cuts off the high frequencies.  | |
LOW FREQ  | 20–16000 (Hz)  | Adjusts the frequency range that’s boosted or cut by the LOW GAIN parameter.  | 
LOW GAIN  | -24–24 (dB)  | Adjusts the amount of boost/cut applied to the frequency range that’s set in LOW FREQ.  |
