Jen Electronics SX-1000 Synthetone

Jen SX-1000 Image

The Synthetone SX-1000 is an old Italian basic mono-synth. It has a single analog DCO with three waveforms: sawtooth, square, and PWM (Pulse Width Modulation). There is an analog filter (12dB/octave) with cutoff, resonance, and LFO modulation. There is also a simple ADSR envelope for shaping your sounds. In addition there are also white/pink noise generators a glide effect and a vibrato effect. It's known for fairly stable tuning too. Probably its best sounds are the lead ones, the basses aren't that deep but it sure can scream!

What it doesn't have is MIDI, CV/Gate or any other form of control. MIDI retrofits can take care of this however. Unfortunately there is no patch memory, and there is no way around this limitation. Its knobs are boldly colored and well layed-out for easy hands-on access; but you'll need a Polaroid camera if you want to store your patch settings! Also lacking are an arpeggiator, sequencer, pitch/mod wheels, and effects. Nevertheless, this Italian vintage synth is a very cheap entry-level analog synth that has some unique sounds and characteristics worth checking out if you find one. It's been used by Future Sound of London, LFO, Nexus 21, Altern 8, Eskimos & Egypt, Fillmore, Man Machine, Tim Simenon, Broadcast, Plone, Luke Vibert, Ladytron, Prodigy and Herb Legowicz of Gusgus.

Does anyone have any information on 'Jen' as a company? Did they produce any other synths or just the sx1000 /2000? Thanks.

@Fred, I got mine for 100 quid and use it all the time! I find it pretty versatile when I put the time in and mine is half broken (m110 is dying) the thing with these synths now is their prices tend to be that low that younger producers are starting buying these as their first venture into 'Analogue' synthesis (Had to be careful there...) I'd definatly disagree with it being a Novelty device, something like Tenori On is a novelty, This is one of the only still affordable vintage synths, It may not be as powerful as one of the japanese synths from the same time but it does it job, and well.

I have a yen sx 1000, best white noise box for it's year, only issue was when using the note follow, it failed going down. it's under my sons bed next to a guitar amp I found some time ago. we got it out and after a few mins of repeated key presses it sprung back into life! it had been there unused since 1995! next to my poly six and poly 61! as you may have guessed the korgs have issues! I will sell all of these only to someone who will nurture these as i did! so rare and mean so much to me that ill leave them there for another 15 years! and still wipe clean the battery terminals on the korgs!
