3003 Filter Module
Description
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.
!
Our 3003 filter has the most gentle sonic touch of its partners in the Boomstar fold, but nevertheless is quite capable of
shaping precise, very dynamic tone. Whether or not this STUDIO ELECTRONICS filter is filling its traditional baseline boxing
niche, driving a harsh, liquid, acid-like tone, a softer more rubber-bandy SH-101-ish presence, or out of the bass range
altogether, leading the way, all is within easy reach of this surprisingly warm and versatile VCF. The 3003 can be distinctly
vocal at times, especially when one is willing to put grittier, more distorted desires aside.

Potentiometer Potential
Seven attenuation pots control the FREQUENCY, RESONANCE, FREQ CV 1, RESO CV, FREQ CV 2, INPUT and OUTPUT,
delivering smooth, detailed, and complex expression.

Switch It Up !
Classic Minimoog FULL and HALF strength filter frequency keyboard/voltage tracking for rounder low end with brilliant highs.
!
Patch It Up
Seven patch points: 1 V/O, FREQ CV 1, FREQ CV 2, RESO CV, INPUT and 2x OUTPUT direct the deepest manipulation.
