2144 LPF

LPF based on the SSM2044

The ES 2144 LPF is a classic analog filter with a 24dB per octave slope.

It uses our 2144 submodule which features a reissue of the renowned SSM 2044 IC that formed the filter section for countless vintage synths. The filter's tone is warm and creamy at low resonance settings and moves into fat, over-driven squelches at the higher end of its range. It will self oscillate when resonance is cranked and outputs a pure sine tone. In addition, the frequency CV input tracks volt per octave allowing it to double as a sine wave VCO.

Available assembled or full DIY kit with all SMT installed.
