Doepfer A-103

Module A-103 is a voltage controlled low pass filter with 18dB/octave slope.
The circuit is based on a modified transistor ladder (Moog ladder) and is a reproduction of the legendary TB303 filter.
As for the rest the A-103 is identical to the A-120 Moog low pass filter (same controls, inputs/outputs) only the filter sound is different.
