If you want acid house, this is how you get it…the filter is an essential part of the signal path in a tb303 and this recreation is somewhat similar palette, of course in design not the same filter. Selling only cause I want to finance a Squack Dirty VCF that suits a little more my setup.

MRG LPF/a

The MRG LPF variant A is a rework of the classic 24dB filter LPF .

It is based on the AS3320, a clone of the CEM3320.

On a filter design level, a very subtle change is introduced, one of the four poles is misaligned from the other three, creating a somewhat gentler resonanse response.

The panel is redesigned, giving more control to the cutoff handling: 1V/O tracking and attenuated CV control. An input gain saturation is also added.
