AM 4075 - ARP 24dB Low Pass VCF via this auction
Overview
This is a 4-pole low pass filter based around a cascade of integrators. It is temperature compensated and it appeared in later ARP 2600 models. Its cutoff range was severely limited to just 12kHz by a design error, which can be easily corrected. This is an excellent filter, with a clean low distortion ouput that will oscillate at higher resonance settings.
Format
Module Format is 5U MOTM.
Notes
Module was built my myself and has been tested prior packaging. I used it only in smokefree studio..."

Oakley Journeyman Voltage Controlled Filter Module
Overview
This is a Clone/Redesign of the Moog Journeyman Synth. Its completely unlinear response and discrete circuitry gives it a unique sound of its own.
Partially modelled after a classic Japanese filter design from the mid to late 1970s, the Journeyman can be configured in either -6dB/octave high pass or -12dB/octave low pass modes by the flicking of a switch.
When two of these VCFs are used together, one in HP and the other in LP, then the effect is astounding.
Format
Module Format is 5U MOTM."
