“Selling sx1000 synth. Powers up but no sound coming out. Selling as is for parts and spares.” Link
“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
Generally in good condition with only the odd scratch and mark on the wooden exterior. As you can see from the photos, 12 of the 24 coloured labels on the controls are missing but this is only a cosmetic issue. ” Link
– sold as is, broken
– for spare parts only
– enclosure in very good condition” Link
The pink noise generator can sometimes take a bit of persuasion to get into place, but i am told this is just a £1 chip replacement from maplin. Not brave enough to open her myself! ” Link
“All knob caps are present and correct. Everything is working, nice little synth.
Some of the pots are a bit scratchy when moved but sounds great if you dial in a sound – so could do with a clean.. ” 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
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.

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
Unit is in good condition
All functions have been tested and work properly
The one problem is no matter what key you press on the keyboard you get the same note
Filter sounds great, self oscillates
I believe the color inserts on the knobs are incorrect” Link
• 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
“In excellent condition including original pre-set cards and instruction manual.” Link
Had this for years,
In good working order,
Some crackles when you twist several of the control nobs,
coloured stickers missing off of 12 controls,
some scuffs to corners of unit,
Tested at home all seems to work well,” Link
” 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
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
“Fair condition consider the age ” Link
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
“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
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
Works perfectly, no crackly pots at all. Wooden end-cheeks in excellent condition and most importantly all, yes, ALL of the coloured knob tops are present unlike all items listed on Ebay in recent memory!
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
” lovely sounding synth fully working
just has a few control knob tops missing ,, see pics” Link
” Jen SX-1000 Analogue synthesiser win good condition missing some knob caps. It works but some pots need a clean and crackle a bit. comes with 6 patch sheets.” Link
“Jen SX 1000
Vintage Jen SX-1000 analogue synthesizer in full working order has some coloured control caps missing and shows general wear.
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
I’m having a studio clear out. This JEN has sat in my smoke free studio for years. Occasionally being called upon to deliver a fat bass line, or vintage lead riff.
It’s in good condition considering its age.. But usual signs of wear also … But hey this synths like 30+ years old.” Link
I’m having to sell due to being skint (thanks huge dentist bill).. It’s fully working and in good condition for the age, probably built around 1979 looking at the serial number.
The condition is good, not mint as there’s some dings and scuffs in the wood cheeks, but what you’d expect for a synth 35 years old or so. The metal panel has some slight discolourization, as can be seen in the photos, but there’s no rust coming through. I’ve always given the synth a polish every month to keep it protected and it’s never got any worse.
One of the previous owners also removed the red anodizing from the knob caps in the VCO section. Personally I think this makes the Jen look less toy-like (I was never a fan of the muticoloured knob caps). all caps are present.
I’ve serviced the synth, gave all pots a good clean & replaced one. I’ve also modded the synth a fair amount, but still keeping the stock look (apart from 1 small 3 pos switch on the fascia & Audio In jack on rear)
I followed mods from various sites on the net. especially Neil Johnson’s page. (where he proves that it has a 24db filter NOT a 12db as everywhere else states)” Link
“Meet Gunter. He’s not the most handsome chap, he’s Italian made with a German name. He has one knob missing, which he is slightly embarrassed about, but can easily be replaced. His pots need a clean too. The main issue with him though is his LFO, it doesn’t go fast or slow when you turn the LFO dial. The tone remains static without cycling. Apart from that he works fine and sounds good.” Link
On offer here is a nice example of a late 70’s Jen Synthtone SX1000 mono synth. Recently serviced, it all works perfectly & is in good condition. ” Link
“Brilliant 70’s monophonic synth from JEN in good condition and fully working,recently serviced, was initally made from two units and has the Kenton socket kit (V/Oct) installed.” Link
A good example of an ’80’s synth in full working order.
Some of the colour coded tops have gone missing of some of the controls, but otherwise everything appears to function as it should.
A good opportunity to get some classic synth tones cheaply!
Thanks for looking.” Link
Overall in very good condition. There is a bit of noise on 3 of the pots and some minor wear to the wood casing. All coloured control caps are in place.” Link
“Full working … Good condition” Link
“Not your standard weedy SX1000! This has a most desirable Sub Oscillator circuit added, totally ups the synths sonic capabilities
great squelchy bass, juicy leads, the sub osc also imparts “that 70’s searing/tearing, slightly overload oscillator sound found in the MicroMoog (which I also own) condition is a new as you’ll find, all knob caps present,no broken bits, one owner unit! comes with chrome plug in music stand and a printed (very short) owners manual. Totally timewarped!! (2 ADSR’s.LFO,cutoff/resonance.white/pink noise source-shared with the Sub oscillator, glide pulse width modulation,square,sawtooth waveforms, 37 note)” Link
“I HAVE FOR SALE A VINTAGE JEN SYNTHETONE SYNTHESIZER SX1000.THIS WAS MY BROTHERS AND I`M CLEARING OUT,I DO NOT KNOW MUCH ABOUT IT,WE TRIED IT THROUGH AN AMP RECENTLY AND IT MADE NOISES BUT SEEMED QUIET ALTHOUGH WE DO NOT KNOW HOW TO USE IT PROPERLY.TWO METAL CAPS ARE MISSING AS CAN BE SEEN IN PICS.IT HAS AN OLD STYLE PLUG THAT WILL NEED CHECKING.ONE OF THE KEYS IS CRACKED AND STAYS DOWN AND SOME OF THE WOOD EFFECT STRIP IS COMING AWAY AT THE BACK AND A PIECE NEEDS REPLACING,SLIGHT RUSTING TO BACK.NOT TOO BAD CONDITION FOR IT`S AGE AND WITH SOME TLC I THINK IT WOULD BE A GREAT ITEM.I WOULD PREFER PICK UP BY THE BUYER.” Link
“Here we have my beloved Jen. She is a beautiful thing in great condition as you will see in the photos. Built in around 1978, the Jen was the poor mans Moog. Still very highly respected today and very useable.
The externals are in very good condition. The control surface shows little sign of wear and all knobs are intact. The wooden side cheeks are in good condition too but do have some “age related marks” but that is about all.
All keys work and are responsive. As with most electronics of this age the pots are a bit scratchy but all work. I have not used this for about 5 years but I seem to remember it as being less noisy, therefore I think that the pots may recover with use.
The Jen is fitted with a flying mains lead, this is fitted with a vintage mains plug, in keeping! Output is via a single Jack socket.” Link
