"From the early 1980's with rhythms, arpeggiator and a stereo chorus."

this auctionvia the listing: "This is an unusual old syth I'm guessing it was designed for the home market. it has number of preset tones the only adjustment over the tone is the sustain there is a very luch chorus/ensemble effect.
Its a very warm sounding synth and the drums sound like they are analogue and sound great too.

the only fault is the stereo button is missing but the effect can be turned on and off with screwdriver. the built in speakers sound quite bad but plugged into an amp it sounds wonderful.
If you google DK-20 there is a video of one in action." [video above]
