"The Jen SX1000 was released in 1977 for £210 and was described as "A fine box for mucking around with, or for learning about Synthesis. A first class first time buy"
It was eventually discontinued in 1982.

It has a short 37 note C to C keyboard and 24 pragramming controls with which you can make your own crazy sounds, or program in some of the suggested sounds on the 7 printed sheets that sit over the controlls. The settings you can make from these sheets are as follows.
Brass 1 and 2, Hammond Organ 1 and 2, Human Voice 1 and 2, Violin, Cello, Synthesizer, Electric Drum, Piano and Flute. There is also a blank sheet which you can record your own settings."

"The SX-1000, also called the "Synthetone", is a monophonic synthesizer with a 3-octave, 37-note keyboard and a black front panel. It makes huge / fat, analogue lead and bass sounds."
Update via Till "Qwave" Kopper in the comments:
"There are no white ones. The white thing you see is a paper wit punched-out knobs to mark your own setting or the preprinted factory ones. The factories had two sounds on one card: one marked red, the other blue. You can see the red and blue names on the picture of the white one just above the keys in the middle of the keyboard range.
Just have a look at the white ones auction's rear: you can see the paper not lying perfectly flat on the front panel.

So there are no white Jen Synthetone SX 1000 known to exist, although so many claim to see one. But all pictures of white ones show these papers.

I got a Jen SX 1000 with these paper cards. A real nice beginners synth. And the filter of it is a 24 dB filter. Some people always tell it is 12 dB. Just listen to it or have a look at the schematics here.


keep on turning these knobs
