This is a KORG V.C.F FK-1 analog filter, originally sold in the 1970s.

This is an effects unit that takes the VCF (Voltage Controlled Filter) from an analog synthesizer.

It can produce the unique analog sound of the 70s.

Tested and confirmed working with guitar, bass, keyboard, sampler, rhythm machine, etc. While no crackling was found in the main unit itself, there is a faint scratchy sound when operating the foot pedal.

The included foot pedal allows for remote control of the frequency variable range.
For instruments like guitar and bass, the foot pedal enables a wah effect.

The instruction manual is a copy (please refer to the photos).
The original box is not included.

As this is a very old vintage unit, there are scratches, peeling paint, rust, discoloration, and scuffs on the main unit and foot pedal.
