CFA Sound FilterGrizzly 2
Key Features
- Tube-based filter drive unit that adds harmonic saturation before the filter stage, doubling as a standalone distortion effect
- Classic analog ladder filter design with 4-pole lowpass and 2-pole highpass modes for deep or gentle frequency sculpting
- Passive-controlled feedback circuit that enables self-oscillation and resonant harmonic buildup
- 2x oversampling with anti-aliasing algorithm to maintain signal clarity at high drive and resonance settings
- Two switchable GUI skins for customizing the visual workflow
- Standalone filter module extracted from the MonoGrizzly 2 synthesizer engine
Description
CFA Sound FilterGrizzly 2 is an analog-modeled filter effect plugin built around a tube-based drive unit and classic ladder filter architecture. Developed by German sound designer Martin Breuhahn, it delivers the same filter engine found in the MonoGrizzly 2 synthesizer as a standalone effect.
The signal chain starts with a tube saturation stage that adds harmonic richness and warmth before hitting the filter section. This drive unit is central to the plugin's character, producing everything from subtle analog coloring to aggressive overdrive that one reviewer called their go-to distortion unit.
The filter module itself pairs a 4-pole lowpass with a 2-pole highpass, both modeled on classic analog ladder designs. A passive-controlled feedback circuit feeds the filtered output back into the signal path, creating the self-oscillating resonance and harmonic complexity associated with vintage hardware filters.
Beat Magazine Germany awarded it 4 out of 6, praising its convincing tube simulation and warm, rich sound. The plugin includes 2x oversampling with anti-aliasing to keep the saturation and resonance clean at high settings.
FilterGrizzly 2 runs as a 32-bit VST 2.3 plugin on Windows. It ships with two interchangeable GUI skins and a detailed manual covering all parameters and installation steps.

Frequently Asked Questions
Does FilterGrizzly 2 work in 64-bit DAWs?
FilterGrizzly 2 is a 32-bit plugin. It may work in 64-bit DAWs through a bridging tool like JBridge, but CFA Sound does not officially guarantee compatibility in that configuration.
Can FilterGrizzly 2 be used as a distortion plugin?
Yes. The tube-based drive unit produces saturation that ranges from subtle warmth to aggressive overdrive. Users on KVR have noted the drive section is strong enough to serve as a dedicated distortion effect on its own.
Does FilterGrizzly 2 include any modulation features like an LFO?
No, FilterGrizzly 2 does not include built-in LFO or envelope modulation. Filter cutoff and other parameters can be automated through your DAW's automation system to create sweeps and movement.
