“Here is a really nice Casio cz-1000 vintage phase distortion synthesizer keyboard. It is a cz1000 model. It operates on batteries. We tried all the keys and functions and everything seems to work fine. The only thing I noticed is when I did the pitch bend, I can bend the tones up and down. But if I push the pitch bend all the way up or all the way down, it makes a high pitched noise. I am not sure if that is normal or not. It comes with a casio cover. One of the seams is kind of coming apart, but the cover is still functional. It has midi in and outs on the back. As well as the audio outs and plugs on the side.”

” Very nice vintage Casio CZ-5000 digital synthesizer. The flagship of Casio’s professional line of Digital synths in the mid-1980’s, this is a surprisingly deep and unique synth. In very nice used condition – all sliders and buttons are there, all keyboard keys function. The paint and button markings are also very good. Very nice cosmetics in general, just some scuffing, smudges, light scratches and an area of speckling from use and age. With 2 original manuals (see pic), and even the original Casio carton. I have not tested all the functions (not sure how the sequencer is programmed, for example), so I can’t guarantee absolutely every control, but everything I have tried seems to be working fine.”
