What Is BPB Dirty Filter?
BPB Dirty Filter is a dual filter effect with tube distortion. It features a high-pass and low-pass filter, a Slope control (12, 24, 36, 0r 48 dB/octave), a Mix knob, and Volume control. However, the most important parameter is the Drive knob which controls the resonance for both filters and the amount of tube distortion that is applied to the signal.
By boosting the Drive knob, the user adds resonance and distortion at the same time. As a result, BPB Dirty Filter sounds somewhat similar to a multi-band distortion effect. This is because the cutoff frequency will be distorted the most and the user can focus the distortion around a specific area of the signal.
How To Use BPB Dirty Filter?
There are many ways to use BPB Dirty Filter as a standard filter and a distortion effect.
With the Drive set to zero and the Slope set to 12 dB/octave, you can use BPB Dirty Filter as a gentle transparent filter for removing low-frequency hum or high-frequency noise.
Set the Drive to 35 and the low-pass Cutoff frequency to around 45 Hz to add thump to a kick drum. The same can be done to snare or any other percussive instrument. Experiment with different Mix values to find the perfect amount of distortion for your drum loop.
Of course, you can always go bonkers with BPB Dirty Filter. Set the Drive to 100 and increase the slope to enjoy complete audio annihilation. Again, the Mix knob is your friend if you want to get some of that crazy distortion without completely destroying the incoming audio.
