When you're looking for a bit of that vintage feel, Ladder filter will twist your basses into squelching retro-licks akin to those of the Moog or the 303. Crank the drive up an extra notch and it will even function as a warm distortion.

The Ladder Filter simulates low pass filters found in classic hardware synths.

Cutoff knob - The filter cutoff frequency.
Resonance knob - The filter resonance setting. High values will make the filter resonate at the cutoff frequency.
Topology - Selects between transistor ladder and diode ladder topology. The diode ladder have a slightly more gentle rolloff after the cutoff frequency. The two topologies also behave differently when saturation is enabled.
Saturate - Simulates saturation of electronic components in the filter.
Drive knob - Simulates overdrive of the components. Only available in "Saturate" mode.
Bias knob - Simulates bias voltage over the components. Only available in "Saturate" mode.
