Dub Filter is a filter plugin modeled after King Tubby’s iconic Big Knob, a passive high-pass filter with eleven frequency steps from 70Hz to 7.5KHz. This filter defined the sound of the entire "roots" era of Jamaican music. On top of the main stepped Frequency knob and the Impedance (resonance), the filter also offers control over its behavior including Magnetism, Character, Dynamics, and Artefacts controls. We have also included two modulation sources, LFO and Envelope Follower, to enhance the creative possibilities of the plugin, from rhythmic pulsations to organic filter movements. Available as Standalone and AUv3.
