"This is the original K1, not the later K2. A classic with a unique sound that can be very useful in an era where everybody else is using the same boring-sounding modern synths.
This one is branded by Univox & sounds amazing. Huge bass for a single oscillator mono synth. Really cool flute-like tones, chorus sounds, sound effects, leads, etc. as well. Onboard effects include portamento, vibrato, bender, repeat, sustain, expand & bright. The high & low "traveler" filters are also killer. Rare vintage Korg sticker on the wood & everything is original as far as I can tell.
Everything functions as it should including the Hi-Z output which I recently fixed. The highest key is at slight angle (see photos) but works perfectly. Also, there is some wear/stain on one side that is shown in the photos. The wood side panels can be replaced if desired as there is a company in Germany making replacements. Lastly, there is a screw missing on the top panel which doesn't affect playability or functionality in any way. Like any vintage synth, if left unplayed for long periods of time, some of the switches can get scratchy but this goes away quickly with use and/or Deoxit.
*I have just retested all functions as of 10/24/2020 & everything is working/sounding great except for the following minor issues:
-The "Scale" switch can make a small "pop" sound similar to turning on a guitar pedal when adjusted. I don't find this to be a problem as I generally don't adjust the scale when recording.
-The "Mode" switch can sometimes not register & just needs to be moved around a bit to get going again.
-The Vibrato switch did not turn off the effect - however, simply turning the vibrato "depth" slider to zero turned it off."
