This little and inexpensive filter box is unbelievable, although you won^t see what^s inside at first glance.
The envelope follower is level independent and has 2 actual envelopes internally - one fixed and one changeable referential envelope. They both are divided analog which produces a level independent envelope within far ranges.
The filters are made from discreet parts and form a 24 pole lowpass filter transistor cascade.
They can - in any thinkable way - be self feedbacked and be coupled or feedbacked with each other, so that extreme sounds and chaotic states create - all what you need today for creative analog sound design.
Unbelievable bass gains or screaming scratch sounds are no problem.
The mix pots are zeroed in center position; any other angle will couple or feedback negatively or positively. FM in both directions is also available.
Connections: Power 9V~ AC, Stereo In 2x 1/4 inch, Stereo Out 2x 1/4 inch
