Super unique synthesizer from Kawai, tested in great working condition. Previous owner shortened the AC power cable as picture.

FROM VSE:

The K3 is a wavetable synthesizer. It has 32 waveforms, some of which are samples of acoustic instruments like piano and percussion as well as some unique waveforms. By combining two of these waveforms you can create unique new sounds or add a twist to a traditional sound. Since there are only 32 of these waveforms, the K3 also features a programmable digital waveform where you can tweak the harmonic content of a waveform allowing for added flexibility and range of sounds.

What's really neat about the K3 is that (unlike the K1) it has analog filters and envelopes! So although the sound may be digital at first, it sure does get warmed going through the filter. The low pass resonant filter even has its own envelope generator. There's also a high pass filter and a highly flexible LFO. The K3 is an interesting synth, nicely bridging the gap between the analog and digital domain of vintage synthesizers.
