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

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

Moog Rogue

“Moog Rogue Synthesiser.
I’ve had this synth since the mid eighties and it’s never been gigged, home use only.
Perfect for soaring lead sounds or for thumping bases and is quick and easy to set up.
Still in really good condition for its age.
Fired this up today and the sound is stable. The only small issue is a little bit of fader noise on the AMT, OSC1 and OSC2 but this is only when sliders are moved and I’m sure this will be easy to rectify.
It still has original MOOG power supply and the original packaging although this is beginning to show it’s age now. Also included is an owner’s manual which is in good condition which I received from Moog back in the eighties. ” Click here to search for synths on eBay

Roland D-50 Project Machine

“Hello!

You are viewing a Roland D-50 being sold AS-IS or for PARTS.

Here is what I know: I purchased unit on eBay two years ago, wanting a vintage D-50. The unit worked perfectly on arrival and for about six months afterward. Then the unit would only play sounds on key release. This problem is known and usually is indicative of a bad keyscan board or connection to it. If you are handy with electronics, it may be an easy fix if you can track down the parts. I have searched for months here looking for a complete keyscan board to no avail.

The unit was cleaned (previous owner had two-sided foam tape and stickers all over unit) and was working perfectly. Keyboard itself feels Roland-luxurious as original. No dents/dings in the chassis, however there are missing screws on the bottom panel (indicating it was serviced before) and the rubber feet/screws are missing.

The unit DOES play perfectly via MIDI, is capable of sending/receiving sysex, all buttons are functioning as well as MIDI in/out/thru. All audio/phone outputs working. Display is about 70% brightness from new, no bad elements on LCD. Joystick functions perfectly. Sound (via MIDI) is original quality.

Will ship packed in gig bag (no charge, just for protection) and carefully wrapped. I have three road cases, if you want one, just contact me after the auction and pay the extra shipping. Unit is heavy, hence the shipping charge. ” Click here to search for synths on eBay

Roland MKS-80 with Roland MPG-80 Programmer

” You are looking at a Roland MKS80 Super Jupiter and the MPG80 programmer. I purchased this synth in 1987 and have owned it ever since.
At that time I had finished a touring music career and was beginning a career in film scoring and theater sound design. This synth has never been gigged live. It has been used in a number of my small home studios over the years only. I used the synth for my work for about nine years until about 1996 when I completely stopped making music and started a small business. The synth sat unused in a box until about 2012 when I began to dabble in music again. It basically sat unused for 16 years.
I have just replaced the dust protectors for all of the sliders in the MPG-80 and completely cleaned the sliders internally as well as the PC board. It is like new at this point. The new dust protectors are a bit stiff and will eventually wear in. You can feel the fibers of the material rubbing against the slider shafts, but the actual sliders are extremely smooth and function like new. They were completely tested before replacing the dust protectors. The manufacturer of the dust protectors assured me that the material will wear in with some use. It’s rare to find an MKS80 and MPG-80 combination with this kind of low mileage on it.
The current pandemic situation has left me no choice but to sell some of my equipment in order to pay the bills.
I will include all of the factory racking hardware for both the MKS80, and the MPG-80, the original user manual (both the MKS80 & MPG80), the C64-C memory cartridge, and the original programmer DIN cable that connects the MKS80 with the MPG-80.
I will ship the purchase in two separate boxes. I want to be sure that I can safely protect the sliders on the MPG80.” Click here to search for synths on eBay
