Octave Kitten

“Wow this has some history with me playing support for loads of groups in late early 80s including throbbing gristle…back in the day

This is the synth that will get you the original sound of back in the day…

So…its been retired and in the loft for decades and needs a new home

It has some broken knobs and one of the keys needs fixing but it works!

So with a few quid spent it will be good as new

I also have the original manual!” Click here to visit listing on eBay

Yamaha DX100

“Selling this Yamaha DX100 that I’ve inherited a couple of month ago (with a Korg Polysix that you can find on eBay as well) and didn’t played it that much as I don’t play keyboard really.. So far all the keys and buttons works. ”

Roland D-110

“Roland D110 synth. I would describe this a tatty example of this unit and I have set the price accordingly. Please check the photographs, you will see what I mean.

The mains cable was replaced some years ago, but I lost the cable clamp in the process! but if its racked, should be ok.

The volume knob was missing when I got it, and for what I used it for, it was never an issue so I never got it replaced. I used the 8 outs into a mixer.

I have powered it up and it works, so if you want a cheap rackmount synth with 8 separate outputs, this could be for you.”

Korg EX-800

“This unit is in excellent condition for a piece of equipment this age. Probably just needs a little dusting and you’re good to go. As with any vintage music/audio equipment you’ll want to treat it with care. Some EX-800 units have been known to have a leaky battery that can be a problem, but as shown in the photos, the battery in this unit appears to be in good shape (and I believe it is the original, unless the previous owner changed it out, which is unlikely).

This listing includes the EX-800 unit only. Does NOT include power cord, so you’ll need to have or get a 9-volt power supply with “center pin negative”. You can buy adjustable voltage power supplies online, but get one that outputs a reliable voltage, as any vintage synth like this can sometimes behave oddly if the power is not at the correct voltage (such as making buzzes, or clicks, or not loading program data reliably).

I do not have the EX-800 manual or any additional paperwork. You can probably find that documentation online if you need it.”

Sequential Circuits Pro One

“Legendary analogue synthesizer from 1981. Without a shadow of doubt the most powerful mono synth ever produced. This thing is completely devastating for bass, but also excels at leads, drones, percussive sounds and all kinds of other complete madness. A truly wild and amazing instrument. The real deal – none of this modern clone/reproduction business.

This one has the much more desirable J-Wire keyboard – and is serial number 6732. A bit of research online will reveal that this is what you want – the first couple of thousand has problems with the internal power supply and the ones after 8000 had the badly designed membrane keyboard. The synth was serviced a couple pf years ago and is working flawlessly (I can provide the service invoice). The synth is in immaculate condition cosmetically. Wooden end cheeks are in really nice condition. All in all for a 40 year old unit this is a really incredible example. An amazing and inspiring instrument but also a solid investment, the price of these things is rising all the time these days. Collection in person is ideal – but I’m happy to discuss shipping options at buyers expense” Click here to visit listing on eBay

Korg Poly 800II

“I bought this to try to fix up but the condition ended up being rather atrocious. It likely came from a garage, basement, or outdoor shed – it doesn’t have an odor though. Upon opening it up, it had all kinds of dust and dirt which I vacuumed out. I installed a new battery and repaired some wires that had somehow been broken. I cleaned the tops of the keys and key contacts.

It powers on on the first attempt, but then when turned off and on again, it won’t power on until being left off for a while. I tried reloading via tape input dozens of times, but got an error message each time. I tried loading patches via sysex but nothing brought the patches back on. All the patches are quiet, or noise, or bad sounds although the filter does sound nice and it does have some oscillator sound as well. I had limited success trying to program a patch, turning the noise off and adjusting the decay and release, and delay. It seems it’s something more wrong with it than simply re-programming the patches.

All the keys trigger. The pitch bend and mod stick doesn’t work and sound the way it’s suppose to. The buttons all double trigger when pressed most the time. The sliders move, although a little rough, but it was hard to test their functionality given that the patches are so bad. I didn’t bother messing with the sequencer and just ended up giving up. ” Click here to visit listing on eBay

Korg DW-6000 Project Machine

“We are not Professionals….Item is pre owned. Sold this unit prior, buyer returned stating that item Does not work properly. It’s hard to tell exactly what’s wrong. The keyboard only plays one note for most patches. Isn’t responding properly. Editing doesn’t seem to work properly. The unision and poly mode buttons didn’t seem to do what they are supposed to do. Possibly memory is corrupted or at least the patches have been messed up. Therefor selling item AS-IS, Parts/Repair. NO RETURNS.! With power cable, no other accessories. As pictured. Nothing else.” Click here to visit listing on eBay

Yamaha TX7

“Yamaha TX7 Desktop DX7 FM Module. Condition is “Used”. Dispatched with Royal Mail 2nd Class.

Some signs of wear (it’s from the 80s!). Working perfectly and sounding brilliant. Great space saving way of getting the classic DX7 sound. You can load any DX7 sysex patches into it and you can program it externally with something like Dexed on a computer if you want to delve into FM synthesis.”

Teenage Engineering OP-1

“I’ve had this thing for a few years but sadly I never seem to touch it. It’s definitely a unique and fun machine and I hope it goes to a good home. I’ve only touched it a few times so the condition is great. However, the lower right corner of the screen has some marks on it as show in the photo. I have no idea what it’s from but it doesn’t affect the visibility of the screen.” Click here to search for synths on eBay

Roland Jupiter 4

“Roland Jupiter 4 Analogue Synthesizer. Condition is “Used”.

Perfect working condition, All voices in tune, no issues, no crackles, extremely well cared for but used extensively. It did have an issue with Noise bleed and one voice kept dipping out in it’s past but it was serviced by James Walker a few years ago and has been perfect ever since.

I never imagined selling this beauty but circumstances change as we all know, especially this year. I will miss this thing.
It has typical wear and tear for it’s age especially on the wooden end cheeks but all in all, it’s in great shape, you have to really look for any marks. Actually, the manual button takes a few presses for it to stay in but that’s all I can think of, worth mentioning I think.” Click here to search for synths on eBay

PAiA 4700 Modular Synthesier

“I’ve been carrying this thing around for YEARS. I keep telling myself I’m going to restore it… I’ve finally given in and am hoping someone will make it go again.

It doesn’t really work, certainly not like it should. It makes sounds but… not really? It also has had some mods done to a few of the modules which you can see in the photos.

It is in a home made plywood case which even still has some measurements written in pencil on the side. I call it The Folk Synth since it has an early American folk art vibe.

The pots date it to 1974, which would make it quite an early Paia. From a little digging there are several places online to find schematics and build docs.

This is definitely a project so expect a fair amount of parts replacement and rewiring. Assume it’s 46 years old and has never been serviced.

Due to age, lack of functionality, and unknowns this is definitely sold as-is and with no reserve. However, I do hope that someone will make this the coolest old time folk art modular ever!

It contains these modules:

2720-2A VCO

2720-5 control oscillator

2720-14 sine/PWM

2720-3L low pass filter

2720-3B band pass filter

2720-12 inverter/buffer

2720-11 envelope follower

2720-4 function generator

4710 function generator

4740 envelope generator

4711 four channel mixer

2720-7 power supply” Click here to search for synths on eBay

Casio CZ-101

“Relatively clean but with some scuffs. Missing the screws that hold the body together other than the two that go in through the battery compartment. Has all of the buttons knobs wheels and inputs/switches that I can tell. Inside all of the boards are very clean. Not sure why it doesn’t power on. I actually haven’t tried with batteries and I don’t have the power supply. For all I know it works. I just grabbed an old 9 V adapter that might not of been accurate and it did not power on with it.” Click here to search for synths on eBay

Yamaha TX7

“This Sound module is in good cosmetic condition and works perfectly. I used this module in my MIDI rack for years back in the day, but have not gigged with it with any consistency in a long time.

It has always been racked and so has some rack rash, but the face is very nice, and the display is perfect. All buttons and switches work perfectly. It has always been used in a smoke free environment.

It comes with great Hammond full draw, Rhodes, Wurlitzer, Pluck Guitar, Strings, Trumpet, vibes, accordion,Pipe Organ, Harmonica, etc FM sounds. These are not all just the factory TX-7 patches but ones that I purchased and used in my DX-7. You won’t be disappointed.” Click here to search for synths on eBay
