A replica of the 4012 filter used in the early ARP 2600.* Steffcorp has set a very high standard when recreating this historical piece of engineering. Built using high quality components and with the attention to keep all the quirks from the original circuit that ARP used. Adjusted for the eurorack form factor and with a skiff friendly "sandwich-layout".
-Frequency & Fine-tune
-Attenuators for Audio and FM inputs
-Buffered inputs & output
-Depth about 35mm.
*The 4012 VCF was used by ARP from 1971 (blue marvin) to the middle of 1976 (grey meanies).
