“The unit works great . One of the d# key is a little crooked so when pressed it tends to stay down till put back in regular position . You can find the keys for really cheap and is an easy fix.” Click here to search for synths on eBay
“Original 1978 Korg MS-20 Synthesizer in excellent working condition.
Used very little and stored in a bag in a clean, dry environment throughout its life.
All parts are in good condition and functioning normally for music making (especially considering they’re from 1978!). ” Click here to search for synths on eBay
“Another hidden treasure from uncle Freddie’s stash… It powers up and plays, not sure if all controls work- I’m not into synths/keyboards, but I did get some fun sounds through the headphone output! It needs a thorough cleaning and restoration/repair or is perfect for spare parts for your Delta. The joystick is broken off but is still functional, three slider knobs are missing, and the sliders and pots and could stand to be lubricated, tightened and/or replaced” Click here to search for synths on eBay

“If you’re looking at this, I don’t need to intimate how great this synth is – the modulation capabilities are unique (particularly with the LFO trick, which this unit performs easily – I will show you how, if you pick her up).
I apologise that the photos look like it’s been taken in a 1970s opium den – I should have taken it to the kitchen for extra clinical, halogen-lit photos. [NEW PHOTOS ADDED!]
This works flawlessly. She retains the Japanese 110V supply, but I will provide a high quality transformer for UK voltage.
My house move forces this sale.
I have swapped knobs with the Korg mixer from the same series. It illustrates the architecture of the synth very well… If you want the original knobs back, I’ll swap it back to standard (but I’m not the first to perform this swap)” Click here to search for synths on eBay

“Selling my Korg m500 , just seen one go for 395
Not as original as mine , theirs had a knob that wasnt original etc , but ill ask less for hopefully quick sale , this is the last of my Analogue collection ive sold off over the last two years ,
This works absolutely perfect , no dodgy switches or crackly pots and sliders
Ive also added a kettle lead socket , instead of the fixed cable normally on them
Let me know if you have a kettle lead as I prefare not to put plug and lead in parcel stop prongs marking synth
This is the SP version with onboard speaker
These sound crap on their own , But add a reverb pedal etc , it completely comes to life ” Click here to search for synths on eBay
“Up for sale the amazing Korg MS 20 from the late 70s. Fully functional, in good cosmetic condition. All the buttons, patches and keys work as they should. I used this synth for overdriven leads, baslines, cosmic fx and somethimes ran samples trough the filter to add some character. I have played the new ms20 and it sounds too clean and the filter does not scream like older version but not to say the new one is a bad synth. That’s why I prefer the old ms 20. I’m selling it because I need to move out and need money to cover my bills. So take advantage to own the true iconic ms 20. It comes with the european plug and psu converter to be used in usa. ” Click here to search for synths on eBay
“This is Korg’s Polysix synthesizer from 1981. A knob for everything and no menus. Good physical condition except for the left rear corner. See photos. I built a new KLM-367 programmer board for it since the old one had the usual battery leak damage. Only the 8048 microcontroller and the Molex connectors were reused from the old board. Looks great, sounds great, everything works.” Click here to search for synths on eBay
“When I bought this synth in 1999, it was already 18 years old. At the time, it was in perfect condition, save for a couple dings in the wood. I used this in several studio albums and it also made more than a few trips to the stage. For about 8 years this was my go-to vintage synth.
As the years passed, I didn’t really play anymore. In fact, it has been in storage, untouched, from 2009-2018. I kind of forgot I had it.
However, when I turn it on today, it doesn’t act the same. What used to be one of my favorite synths is now virtually unrecognizable. There are so many things wrong with it now, it makes me want to cry. I have no idea how to fix it, so that’s why I’m selling it. It makes me sad because I loved this thing back in the day and it’s really cool looking in a studio.
Alas, I will give you a rundown of the things I found wrong today with the Korg Polysix in this listing.
BAD THINGS ABOUT THE SYNTH IN THIS LISTING:
1.) 3-4 of the keys dont trigger sound, this was not true before it was stored, it might be dirty contacts.
2.) The volume knob is somewhat scratchy when turned
3.) The ASDR knobs don’t work correctly. As a result, most of the sounds this synth makes have quick attack, hold as long you press the key and then immediately release when finished. Similar to the dynamics of a brass instrument. However if you turn the ASDR knobs weird things can happen, but not what you’d expect.
4.) Many knobs work sometimes and don’t work other times. Or they don’t seem to be changing the same thing they changed before.
5.) It takes between 5 and 30 minutes for it to get to a state where it can make sound. This is kind of normal (battery issue?) and one of the reasons I stopped using it. “Warm up time.”
6.) It is completely out of tune. While the keys do ascend and descend, none of the notes are a proper interval. An octave is not 12 steps, but more like 11.3 steps. C1 to B2 is almost an octave on this synth. I’ve never seen anything like it.
7.) Some of the buttons are missing. The contacts still work. See pictures for details on the cosmetics.
8.) Sometimes it will start randomly making glitchy and creepy noises on its own. This synth literally seems to have a mind of its own ocassionally.
These are the most obvious bad things I could find. There are probably other issues I don’t know how to test for. Let there be no misconception, this synth is very far from perfect condition and some people might consider it usable for parts only. The only reason I don’t list it as parts only is because it powers up and makes sound and some musicians might be able to use it as-is.
GOOD THINGS ABOUT THE SYNTH IN THIS LISTING:
1.) It is the ultimate “weird noise generator.” Because of all the aforementioned problems, it is nearly impossible to get this synth to make anything remotely close to a normal sound. Almost every knob turn results in something unpredictable; however,
2.) The cutoff and resonance filters still work perfectly, every time, and they still sound great.
3.) The arpeggiator, pitch bend wheel, chorus effect and octave knob still works.
4.) It has never had a problem turning on. The power and lights have always worked. It has powered up without issue every single time.
5.) It’s 37 years old and still powers up. That’s gotta count for something right? :)” Click here to search for synths on eBay

INCLUDING ORIGINAL BOX AND MANUAL!!
Serial #6750 Circa 1982
*** THIS IS THE LOWEST PRICE I WILL GO- LAST CHANCE!! ***
*** FREE SHIPPING if final price goes over $1600
*** 2/16/ 2018 – I have added pics of the wood sides and the original box
This is one very CLEAN Pro-One!! Just serviced and ready to go! Every feature works great.
Not only that, I have the ORIGINAL MANUAL, WOOD SIDES and the ORIGINAL BOX with the correct serial numbers.
I also will include a spec sheet and pamphlet about the Pro One.
ALL of the oscillator chips were replaced (including the LFO) with NOS CEM chips.
Also the power supply was checked out, tuning calibrated and I have replaced ALL of the keyboard’s rubber bushings.
This Pro-One has the more desirable “J-Key” type keyboard which is considered much more reliable.
Once I replaced the bushings the keyboard was a LOT quieter and had a much better feel to it.
Repair work was professionally done by DFX in Salt Lake City (they make great boutique pedals too!).
Cosmetically a 9+ out of 10 it is a beautiful thing to behold! There are normal wear and tear marks on the wood sides (which can easily be sanded out).
Awesome powerful sound, very ballsy and aggressive with its famous modulation capabilities,sequencer and arpeggiator.
Note: There is one knob currently missing (the volume knob) but I will purchase a replacement for the winning bidder and have it sent directly to you.
This is a great example of 1982 synth technology, VERY RARE and COLLECTIBLE, ESPECIALLY SINCE I HAVE THE ORIGINAL BOX it came in and the ORIGINAL MANUAL as well.” Click here to search for synths on eBay
“Hi and thanks for checking out our Listing for
1982 Sequential Circuits Pro One 37 Key Synthesizer – Stunning!
In near mint condition, the only mark on the entire synth, is one tiny chip from the left hand wooden end cheek, otherwise, this superb one owner example is as new throughout.
Original Operation Manual with the original purchase receipt stapled to the inside/back cover
A couple of original write-ups from the time of sale
A dozen or so sheets of Blank Preset diagrams to help you save your favourite sounds when you stumble across them.
Operationally, this synth is perfect and works as if it were brand new out of the box. We have made just one improvement. The keys were a little sticky from lack of use, so we’ve added individual cork buffers to every key. The key-bed was removed to fit these and they have been fitted between the key stops and the framework, giving the key return a much softer feel. All keys were then individually height adjusted so they rest perfectly flat across the register. We think there is no better example out there.” Click here to search for synths on eBay

“Vintage 70s Californian guitar / synth interface from 360 Systems, makes of the Spectre guitar synth which used a SEM.
Ex. Steve Hillage – I bought it from his tech in Highgate many many years ago. I think it may have been used on L. Hope so anyway!
I used to run it with a System 100 – worked really well. Haven’t used it for at least 15 years and it has clearly developed a fault. Triggers but the pitch doesn’t change with the guitar strings/fret position.
I can’t find much info. on this unit on the web so repairs could be difficult if not impossible.
However it is an extremely rare unit in pretty good cosmetic condition with the original hexaphonic pickup (converted before I had it to be disconnected via an expensive Lemo multiconnector).” Click here to search for synths on eBay
“This is the great Oberheim Matrix 1000, with 1000 pure analog patches. This synth packs so many sounds, it can be overwhelming. I’m also pairing it with an Alesis Qudraverb. The two together are perfect for most synth needs. The Obi works great but the volume pot is a little scratchy, I used it mainly with my Keystep for a year or so, and only in my house. From what I was told it is all original and no mods or updates have been done. Not sure if Ive gone through every patch, but the ones Ive used sounded amazing. Quadraveb is in decent shape, Ive noticed that if you move it around alot the output can cut off, but is not really an issue for studio usage.” Click here to search for synths on eBay
