Blue Lantern LM4250

The LM4250 Sour VCF, by Blue Lantern, was inspired by the infamous Polivoks VCF, albeit with some additional circuitry not featured in the original. Unlike its predecessor, the module uses LM4250 IC op amps and contains a bright/dark switch for timbres akin to those produced by a decimator. A switchable internal diode limiter allows users to achieve acutely high resonance—and considering what the original is capable of, that’s saying something!
