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.”

Korg Polysix

“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

“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.”

Korg M1

“KORG M1 is a legendary synth still very popular among musicians. Apart from the incredibly clear sound, it offers a pretty sophisticated sequencer. I’ve used it very few times during the years, but sadly time has left some marks on it: the power button is missing and it presents not many scratches, but few of the keys are kind of worn out, as you can see from the pictures.”

Korg MS-20

“Original vintage MS-20 – the timeless, semi-modular monosynth.

Korg’s MS-20 monophonic synthesizer, first introduced in 1978, is still a coveted instrument to this day, thanks to its thick, robust sound, its powerful, iconic analog filter, and its versatile patching options.

Not looking to get big bucks for this Synth because of the cosmetics.

I have owned it for about 30 years. If you want the original sound it is here for you.

Bought this in 1980 – 81? SN – 145663

It was on the road so cosmetically has scratches, a missing volume knob and 2 minor cracked keys but it works!

I haven’t fired it up on stage since 1997. ”

Korg MS2000R

“Korg MS2000R Rack mounted analog modelling synth / vocoder / analog sequencer.

This is an excellent synth. Easy to use. Great fun to tweak. Wonderful korg analog sound.

Comes with original korg power supply.

It’s got two oscillators which you can sync or ring mod. It also has a noise source.

It’s got distortion and delay effects.

It can work as a vocoder with an external input!

It also has an internal 16 step, 3 row analog style sequencer which you can route to all sorts of parameters. For instance the first row could set pitch, the second could set the filter cutoff, while the third selects the wave form of oscillator 1.

It has a keyboard mode where the row of buttons at the bottom can be used as a keyboard which is great fun when using this as a desktop synth.

It’s in perfect working order. It’s got a bit of rack rash around the rack mount holes and a couple of small scratches on the ears which you can just about see in the photos. ”

Original PSU included. There is a slight crack to one of the knobs (pictured). This doesn’t affect performance, but the purists may want to swap out with a replacement, which you can find online.”

“Selling my Korg DW8000. It’s a great 80’s hybrid digital/analog synth that can make a bunch of great sounds, and has a nice built in delay that can also do some chorus like sounds. I replaced a dead save battery in this a few months ago, so you don’t have to worry about all your patches being lost. One of the D#/Eb keys sticks a little bit, but it hasn’t been too much of an issue in my experience performing with it. Only selling because I got a new synth that I use way more.
