Boomstar Modular 3003 Filter

The 3003 filter is a voltage controlled, discrete analog 18 db/oct ladder low-pass filter, employing hand-matched transistors. Drop the FREQUENCY knob to 0 and things get pretty dull; swing it back up and those "Transistor Bass” highs come crashing through the gate. The 3003’s RESONANCE circuit at max will sing out more than the TB’s signature chirping in a fun, bubbly, if washy, poorer relation, Mini “clone-ish" way; use it tastefully, or throw moderation to the wind for overwhelming chirp force.
