Weird filtering effects and more
The Korg Synthepedal FK-1 was made in the 1970s by Univox.
You can get some really evil filter sweeps with this beast.
The TRAVELER sliders control the amount of the high and low pass filtering effect.
The THRESHOLD knob is a sensitivity adjustment for regulating VCF (voltage control filter) response to the signal going in to the in jack.
The MAX knob provides varying intensity for the expand effect. and BRIGHT extends the expand effect range even further in the high-frequency range.
This particular Korg Synthepedal FK-1 is in good condition.
Has some very minor signs of wear given it's age (1970s!)
Has a small ding on one of the bottom corners. A chunk of paint has been chipped off.
Includes the synth, expression pedal and 5-DIN cable that connects the main unit to the expression pedal.
