King Tubbys high pass filter was known as “the big knob”. He often used it to sweep the reverbs and echos in his dub mixes. This is where the inspiration for HighPass Filter 1012 came from. The 1012 is a 2 pole, 12dB/Octave high pass filter with peak control, input level indicator and transistor drive to boost the signal while giving it some analog heat.
The CV jacks on the back lets you smoothly modulate the filter frequency with control voltage.
