Has midi retrofitted also by a previous owner, however they are mislabelled, I don’t know which way round they go as I don’t use midi. The photo of the wiring inside should answer it.” Click here to visit listing on eBay

Korg, Polysix @ 22 June 2019, Comments Off on Korg Polysix

“The Korg PolySix is an amazing early synth dating to 1981. I obtained this model in the 90s from its original owner. It’s a six-note polyphonic analog beast with built-in chorus, phaser and “ensemble” effects. It’s got 32 memory slots for voices, which can be backed up to old-fashioned cassette tape. I believe this is the model they used for “The Final Countdown,” so you KNOW it’s awesome. Tears for Fears also used a PolySix, and so did Keith Emerson (who I’m pretty sure used every synth). This machine has never been on the road, it’s original owner used it for home recording and I used it for taking up space in my basement. Somewhere along the line, it simply stopped working.

This keyboard has some chipping to the woodgrain finish on the edges and corners, and is missing a few of the little buttons on the top. The buttons themselves appear to work, but they’re all sticky.

PolySix keyboards have had some reliability issues in the past, and this one needs to be serviced. It currently does not play. The PolySix has a NiCd batter that needed replacement, and it is unlikely that the one inside this model has ever been replaced, so that might be the issue – it powers up just fine, but no sound comes out. This is being sold “as is” with no returns.

Reverb dot com shows past sales of these ranging between $800 and $2000, with POOR condition examples selling in the $800 range. This one definitely qualifies as POOR; it’s yours for $700 plus shipping, which is a great price if you know how to service these (or know someone who does). This is a truly monster synth, one of the earliest affordable synthesizers.” Click here to visit listing on eBay

“Here for Sale, I present the Fabulous Korg Poly Six! This is a 6 Oscillator Keyboard that along with the Equally Fabulous Roland Juno 60 (Which I also own) was released in 1981 and turned the world Upside Down!
Sadly, as anyone who is familiar with this Awesome Synth is aware of, it may suddenly just Stop working and No sound comes out of Output jack! And ALL of the LEDs across the Front Panel light up and stay lit (see pics). This is Exactly the case with this one. So, it needs to be serviced. For this reason I am selling “AS IS” with no returns. But, my outstanding Seller Rating (100%) on OVER 327 Sales! With a TOP SELLER Purple Star should alleviate any concerns on duplicity here.

Some of these keyboards have had an issue in the past where the little Blue battery needs to be replaced before it gives out and Damages or completely destroys the PC Board it is mounted on. This is NOT the case with this one. I have owned it for many years and NEVER had an issue with the Battery! Please, observe all pictures that show the boards and everything else to be spotlessly clean with no trace of any battery leakage. I suspect this infamous ‘battery Issue’ only applied to certain Serial Numbers?

Many of these ‘sick’ Poly 6 Keyboards have had sales in the past (and recently!) between $600 and $800, as they are Very sought after Even in POOR condition to replace Boards, Parts, Chassis, etc…on Working or semi-working ones…This one should NOT qualify as a Poor Condition Unit since apart from it suddenly, mysteriously having stopped working it still appears to be in Very GOOD Condition! It should be a Bargain for any ‘Home Techs’ out there who know how to service these. Thus, I am setting the Opening Price accordingly.

Please, note that being a ‘Go Getter’ / ‘Do it Yourselfer’ I first tried replacing the Battery with a Battery of Same brand and Voltage but a little more capacity but, that did NOT resolve the issue (I will be providing this battery as well as original battery). Then I noticed one of the 8 pin ICs seemed to be in poor shape (blackened legs?) So, I ordered a pair of replacements (sn74ls75n) But, only changed one since that also did not alleviate the issue. (I will provide the original chip plus the other 2 New ones) Then I tried replacing the CPU with a New one but, that also did not help (I will also be providing the New CPU as well as the original CPU). The CPU replacement was by far the easiest since the poly six originally came from the factory with the CPU already mounted on a Blue Plastic Socket. 🙂
I am providing all of these details to help anyone who purchases this in his/her repair work.

Please, note, there is Nothing Missing on Keyboard : All Knobs, Pots, Switches, PC Boards etc, are present.
Note also that I am a Home Musician and so have Never Gigged with this keyboards thus, it has No Road Wear such as Dents, Scratches, Dings, Cigarette Burns, Whiskey Spills, etc… ( 🙂 ) I also do Not smoke, Drink or own any pets, etc… ”

“Korg Polysix Synthesizer. This is the one you’ve been waiting for! Excellent cosmetic condition, excellent functionality. All functions work as they should, all knobs turn smoothly, all buttons respond easily, all keys trigger as they should. The battery has been replaced with a CR2032 socket type battery and holder so that in the future, probably way out into the future, the battery will be very easy to change without having to solder. There are a few tiny scratches here and there and there is slight damage to the very corner of the wood sides. The circuit boards are clean. This keyboard was fully serviced recently and it shows in how it plays, sounds and responds.”

All functions working except arpeggiator led light isn’t. No big deal. All CV in/outs working. Arp CV syncs as expected. VCF CV works awesome. Overall great condition inside and out, ready to play and sounds massive. I love this thing but I gotta let it go.” Click here to visit listing on eBay

“KORG Polysix W/Kiwisix Upgrade, Restored W/ PSU upgrade and synthgraphics overlay.

It is fully functional and has been recently serviced, and sounds fantastic.

This a nice example of a Korg Polysix, with those sweet 80’s graphics and wood sides.

There are some small scratches here and there and some wear on the wood sides including on chip on the right hand check in the back by PSU (see pic), but overall for a synth of its age, it looks great!

All pots have been cleaned, PSU was upgraded, unit calibrated, synth graphic was overlayed and firmware was upgraded to latest release, and it sounds fantastic.

Here’s what it adds:

-New KLM367 Board

-512 storage presets upgraded from 64

-MIDI capability

-Key Transpose

-Internal Master Clock

-Internet Upradeble

-Upgraded arpeggiator mode

-Sequencer mode

-Much more reliable stable power supply board ” Click here to visit listing on eBay

“Available for purchase: a Korg Polysix synth, upgraded with a new Kiwi Polysix power supply & CPU/MIDI board, a Tubbutec Polysex osc pitch/drift board, and new key contacts from LA Synth Co. Also included: original manual, Kiwisix box, and original Korg synth brochure. Everything is in solid cosmetic shape and works great. The keys feel brand new after the contact upgrade, and the knobs & switches are smooth and responsive. All button switches have been replaced. There are a few surface marks/scratches on the exterior of the case and could use a thorough cleaning overall. Please see photos for more detail. So there are no surprises, the inside of the case is cracked on the left side, causing a small opening in the rear. This isn’t visible on the side and doesn’t cause any instability. Beyond that crack, it’s a solid unit all around and definitely a one-of-a-kind synth. Sort of sad to see it go, but it isn’t being used as much as it probably should be these days. MIDI, audio, and power cables included.” Click here to visit listing on eBay

“Korg Polysix analogue synthesiser.

In good working condition, this unit has had the troublesome lead acid battery replaced with a new, and non leaking lithium battery. Leakage from the old battery had caused some PCB track damage, this was fully repaired at the same time.

Recently serviced by Synth Repair in London, who also did the battery replacement work some time ago.

This is a lovely synth, a similar alternative to the Roland Juno 6/60, with the advantage of chord memory and onboard effects. It’s in full working order and fair cosmetic condition; there are two small areas where the case paint has been worn away (see detail pics).” Click here to visit listing on eBay

Cosmetically, the synth has a few knocks and scuffs, particularly on the wood.” Click here to visit listing on eBay

“I was given this by an old gearhead who worked with Blur.

Unfortunately it doesnt function properly and emits a piercing noise when turned on and thats it, no keys or buttons work.

Im fairly certain the fault is battery leakage and needs a new motherboard (a kiwisix for example) although I am just making an educated guess and could be wrong.

It has been slightly modified by adding MIDI capabilities which raises the value of the synthesizer significantly.

If you can get it working then you have a rare gem on your hands as its a truly spectacular machine. ”

“Pulled out from storage to find my Mexico excursion.

The warmest analogue I’ve ever played.

Sadly battery leakage has garbled the sound.

This can be fixed for around 200 pounds for a replacement board or you can get the more expensive kiwi board.

It has various scuffs and chips on the wood part.

Right now it’s making rave sounds with distortion so I’m giving a price to better reflect the repair cost needed.” Click here to visit listing on eBay

Korg, Polysix @ 25 August 2018, Comments Off on Korg Polysix

” I am rather sadly selling my beloved Korg Polysix. This is a genuine analogue synth, first manufactured in the early 80s. I bought this particular Polysix from a friend back in the early 90s, and I believe this friend purchased it new. Over the last 25 years I have enjoyed playing this synth in a number of different musical ventures and styles, but now demands of space and cash mean I need to put it up for sale.

Everything is working on this Polysix – all keys, knobs, buttons etc. A few years ago I repaired all the key contacts. I have also changed the battery from the original (the original batteries were well known to leak inside the synth).

The sound of the Polysix is quite unique – very characterful, very organic. I love playing pads and chords on it, but it also handles lead lines and bass lines very nicely. You can stack all 6 oscillators to make fat solo lines. The filter can be pretty extreme. There’s also a great arpeggiator which is fun to play around with. It’s just a great synth for messing about and improvising on, so easy to twiddle a knob to shape the sounds.

Included is the original wooden case (I believe it is the original case anyway). This has a lovely purple fur interior for the Polysix to sit in. I have recently replaced the handle on the case.” Click here to visit listing on eBay

Korg, Polysix @ 25 August 2018, Comments Off on Korg Polysix

“I bought this a couple of years ago for a number of projects and just fell in love with its incredible sound (so so warm – think Boards of Canada for a simple idea). I bought it in the same condition (with the same sticker) for a significant amount of money as they are quite hard to find. It had just had its electronics cleaned out and tested (hence the rather annoyingly glued modulation wheel area – see pix). It has some marks here and there but plays beautifully – remarkable for these synths given their age. It has never been toured and only kept in studio. When not used for recording this was always covered and protected carefully. ” Click here to visit listing on eBay

“Cosmetically it is not so pristine. It is structurally sound, but you can see in the pictures that there are chips in the wood, the panel is scratched, and there is a plastic button missing, which I am sure you can source, and the underlying switch works.

All keys work but a few keys make a minor clacking sound (physically, not through the output). The keybed Is not perfectly level and could use a little love, but you do not really notice while playing and likely cheap and easy should you choose to address it. Despite the cosmetic imperfections, it is very much working, playing, calibrated and ready to do its thing.

Of special note is the bucket brigade ensemble effect which is a large part of what makes this a sought after board. No digital board will really pull that off.” Click here to visit listing on eBay
