24dB/36dB Ultra Fat High Precision Lowpass Filter

Very phat sounding, high precision Lowpass filter with endless possibilities. It's sonic charastics range wide from very sweet pure sounds to ultra deep phat or fm-like tonal digital qualities or even total chaotic, distorted and weird sounds you never heard from an analog filter. Shape your own sonic characteristic!


The first Klangfeld module in Moog 5U size is finished and ready for ordering! A high end transistor ladder with switchable 24dB/36dB Lowpass response, switchable gain-drop compensation of the resonance, voltage controlled resonance, special distortion features, linear filter fm and many more...
