Up for sale is a rare KORG Filter module, which was originally built by Univox for KORG.

It is basically a low pass filter. Controlled by input signal envelope and manual controls. You also can plug in 5-pin foot-pedal to control of the sweep.

It was built in the mid/late 1970ies and is quite comparable to the filter-section of the Maxikorg/Minikorg.

It works for any audio source and is perfect to add a vintage vibe to your sound.
