“Here’s a great little keyboard in fantastic condition, especially considering it’s been around for about 40 years! As well as retaining all the shiny coloured caps that usually seem to go missing from the knobs and switches, it even still has the cardboard templates that feature suggested settings.
There are a few crackly pots that could probably do with a blast of switch cleaner, but every key works just fine and it makes some great noises. I’m no synth expert, so feel free to come and have a look/play and maybe someone can tell me what all these controls do!
You will not find a more complete (and shiny) example of this, which I’m told is becoming a very rare and sought after instrument.” Link

“Lovely little JEN SX1000 that has seen a major refurb to get it into really nice condition.

All the electrolytic capacitors have been replaced with new but most importantly all the horrible old crackly potentiometers have gone to be replaced by very high quality new items. None of the pots make any crackles anymore and the JEN works just how it should. New knobs have been fitted to match the new potentiometer spindles and a headphone amplifier has been added to allow practice without an amp.

The SX1000 was many peoples first synthesiser back in the early 80’s and its sounds still hold a fond place in the hearts of many. They used to be everywhere but are getting increasingly hard to find these days.

Cosmetically this is clean and tidy but its does have age related knocks on the case and the lettering on frequency control have been rubbed away and the paint has needed touching up in that area.” Link

“I dont mind admitting I have not got a clue how to use this, all I can tell you is all the keys work and when turning the knobs they all do something to the sound.

It is in a very good used condition considering its age, it does have some small age related marks and signs of use but nothing that I think needs pointing out. It comes with its original manual but nothing else is included in the sale.” Link

“Hi, here I have for sale a used Jen SX1000 Vintage Analogue Synthesizer.

This mono-synth was made in Italy by Jen and in production between 1978-1982. It has a lovely sound and I personally love the pulse width modulation. Unfortunately I am having to sell due to the amount of room I have and for financial reasons, otherwise it would be a keeper!

It has recently had all of the pots cleaned and they function perfectly, no scratchy pots on this one, the keys all function as they should too and it plays really well for a synth around 35+ years old.

Cosmetically it has 8 of the coloured knob caps missing, this is very common with the SX1000. The keys are not as white as they once would have been due to age. It does have some marks and scratches on the unit but nothing to major, I have pictured a slight dent above the ‘n’ on the rear. Also some very superficial (and common) surface rust marks to the chassis. The mains lead is in great condition.” Link

x1000 “you are bidding on a Jen synthetone sx1000. Firstly: this doesn’t power on. A few years ago it did the same thing and came back to life after a month or so but no joy this time. Have tried changing the fuse but didn’t work and that’s about the extent of my expertise. It may be something you can fix easily and in which case this is a bargain for a fantastic sounding analogue monosynth. The pots were a bit crackly but functioned when it was working so a good clean might help. ” Link

Overall, it’s in really good condition with only light cosmetic wear and a few knob caps missing.

I’ve fitted an IEC connector on the rear so it can be used with a mains lead, plus I’ve replaced some of the capacitors in order to improve it’s tone. I’ve also given the noisy pots a clean with some play and they’re now sounding really good.” Link

a Vintage JEN Synthetone SX1000 Monophonic Analog Synthesizer
with power cord and a one-page Service Manual Schematic (pdf file)
and a 13-page Midi Upgrade Installation and User Manual (pdf file).

Made in Italy. Produced from 1978 to 1982.
A low cost alternative to an ARP or Moog synthesizer with a similar big fat analog sound.
It has a 3 octave 37-key keyboard and has been tested thoroughly and everything seems
to function as it should. Eight of the twenty-four Metallic Colored Knob Caps are missing.
The two veneered wood end caps have some bumps, minor wear and chipping.
One key is chipped underneath (hard to see and does not affect play).
There is quite a bit of superficial rust spots on the back black panel. See pictures.” Link

jen sx1000 “Vintage JEN SX1000 Vintage Analog Monophonic Synthesizer (1978)

Great Analog Synth, originally Italian built, internal transformer modified to work both 120V & 240V without need for switch or external step down transformer.

Fully functional, all keys, knobs, jacks, in full 100% order. A very capable synth on its own with a myriad of filter & midi mods available online (not included.) Very slight surface rust on rear panel which has not changed or degraded in the 22 years I’ve owned this synth. Power throw switch illuminates bright red when synth is on.

Wood cheeks show minimal wear, really not bad for a 35 year old instrument. A number of colored knob decals have fallen off over the years, very easy and inexpensive to replace with DIY adhesive foil or decals (instructions online, not included) none of which effects functionality.

Auction includes:

– JEN SX1000 Analog Mono Synth
– Power cable
– 2 prong to 2 pole power adapter ” Link

I have tried this through an amp and it sounded really good although I dont mind admitting that I’m not really sure how to use this but all the keys work, the knobs all turn, I have messed around with the functions and all of them seem to do something.

It is in a very good used condition with just a couple of scratches to one or two of the knobs and just a little tarnishing to the metal at the back of the unit.

I try to describe my items to the best of my ability and add the appropriate pictures but there If there is any other information you require then please feel free to ask.” Link

sx1000 “Whilst it has obviously seen better days and is in need of TLC from someone who knows what they’re doing, this one is definitely rescuable. The issues as stands, as far as I can tell are:

• one knob is broken off through the shaft, so will need a new pot. Still have the knob though.

• Somewhere between a quarter and a third of the keys are dead. A pretty easy fix, this.

• One key is broken as pictured.

• Keyboard slanted; generally needs attention as per the above.

• It has clearly had some kind of retrofit in its life, but I have no clue as to what, or whether that element works at all.

• Cosmetically a bit of the usual Jen mottling, and scuffs and nicks to the wood. Keys are grubby too; suspect a good clean when the keyboard issues are address wouldn’t go a miss!

The good point however are that is still sounds pretty lovely – filter and envelope seem to work fine. Noise generator a bit hit and miss, but glide, vibrato etc all working.

A bit of an ugly duckling as stands, but potentially great again; used by The Prodigy, Ladytron etc. just needs someone to give it the love it needs. ” Link

sx1000” Here we have one of Martin Hannett’s early synths he was experimenting with in the late 70s around the time he went on to become a producer for Joy Division and John Cooper Clarke,and then later U2 ,The Stone Roses and The Happy Mondays. Like all synths of this age it could do with noisy pots cleaning up but you can still get some great early Hannett synth sounds out of it.
Comes complete with Hannett’s own circuit / preset manual for the synth” Link

used jen sx“Beautiful vintage 1978 Italian monophonic syntehsizer. Good condition, had it serviced a couple of years ago.

Usual issues with vintage synths pots can get a little scratchy if it isn’t used for a while but that clears up by twisting the knobs a few times.” Link

sx1000“Used whilst I was at school, but now no longer working. I’m afraid i’m not getting any sounds now, but when working, it produced some fantastic ‘PHAT’ bass sounds.

Therefore it’s being sold for SPARES OR REPAIR ONLY.

As for the condition, there is slight surface rusting on the control displays, but all the knobs are there, with the colour coding also present.

I’m afraid my parents got rid of the sound cards which fit over the knobs (Ggrrr!!), so they are NOT included.” Link

jen sx1000 “Verkaufe einen älteren, wohl sehr seltenen JEN SX 1000 Synthetone Analog-Synthesizer aus den 1970er Jahren. Habe das Gerät mal zum Spaß gekauft, aber doch nicht genutzt, da ich eigentlich Gitarrist bin. Jetzt nimmt es nur Platz weg, deshalb raus damit 😉

Ich habe den Synthie an Strom und Verstärker angeschlossen und alles durchprobiert. Alle Keys und Regler funktionieren. Bei ein paar Regler ist altersbedingt ein leichtes Kratzen zu vernehmen, das aber größtenteils nach ein paarmal hin- und herregeln wieder weggeht. Wirklich nix erwähnenswertes, aber der Ordnung halber sei es gesagt. Wie auf den Bildern zu sehen ist, sind ein paar Stellen auf der Rückseite etwas angerostet. Oben fehlen ein paar Reglerkappen. Laut Recherche im Netz scheint das eine altbekannte “Krankheit” des Geräts zu sein, insofern sind eh noch viele vorhanden ;-)” Link

Jen, SX1000 @ 02 December 2014, Comments Off on Jen SX1000

The 1uF electrolytic input capacitor which forms a low pass filter has been replaced with a 3uF polypropylene to subtly improve the bass response (one of the common complaints about the SX1000 is poor bass). The potentiometers in the signal path have been replaced with high quality conductive plastic type, which will permanently cure the crackles and noise. The feel is not affected, you cannot tell the difference. Most Jen’s for sale will have noisy pots or had them sprayed with contact cleaner, which only works for a few months. I still have the original components in case you want to restore the original crackly sound.

All the electrolytic capacitors have been replaced with high quality, long life Panasonic electrolytics, so should be good for another 40 years.

This synth looks like it has been been gigged in a previous life and has the stickers (and knocks) to prove it. Most unusually though it is only missing one knob cap, and the rest are the original colours in the correct place. Bear in mind this is at least 35 years old, so is not immaculate but I think it still looks great.” Link

Lovely little analogue synth, great for bass, leads and percussive effects. The PWM is especially good and there’s a separate ADSR for the analogue 12db filter as well as the usual controls for VCA.” Link

The Jen SX-1000 is an old Italian 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. ” Link
