Korg Mono/Poly

“If your a keyboard player and your looking at this then you probably already know about the Monopoly’s fat analogue sound.

I have owned this keyboard since 1985. Yes 35 Years. A lot has changed in 35 years but the Monopoly always put smile on my face.

Reason for selling – moving to racks and space. I know I am not going to get the same warmth, flexibility and enormous sound but sometimes you need to make a change and we have had 35 years together.” Click here to visit listing on eBay

“Long version: This MonoPoly is fully functional. I have owned it for about 15 years, during which time a number of servicing actions have been implemented. All of the pots and switches have been treated (Caig) and last week the main PSU smoothing capacitors were replaced (see owner’s manual KLM-376-MP, C13/14 etc.). The PSU rails (+/-15V and +5V) have been recalibrated to within the manufacturer’s original tolerance and the ripple per rail has been measured to be <10 mV. When I first got my MonoPoly, the front panel screws had rusted, or the surface finish on them had worn off, so I replaced them with button headed socket screws (2.5 mm, see pictures). I have fitted a MIDI interface (MidiPoly, instruction manual/details will be emailed to the winning bidder). This has been done without altering the original instrument, except that now the rear mains subpanel has an IEC mains inlet fitted (rather than a flying lead), with 5 pin DIN MIDI in and out sockets immediately adjacent to it. The front panel (this one is in good condition) is not modified in any sense (no additional switches or controls, for example). All of the original MonoPoly's functions are kept but fitting the MIDI interface adds the following functions" Click here to visit listing on eBay

“This auction is for a used working Korg Mono/Poly analog keyboard synthesizer. This synth has been stored for about a decade, kept clean and dry in a hard case. Prior to being stored the synthesizer was used in a smoke free studio for about 15 years. I am the second owner of this Mono/Poly. This synth is US shipped only.

The synth is working, it powers on and produces sound. Going through the synth all knobs and switches are working, all 4 voices, waveforms, noise source and the VCF/EG/VCA signal chain are working, all ins and outs are working. The arpeggiator works, latches and holds, and will cycle through the 4 vcos, warping them in a deliciously twisted manner when using the X-Mod effects in poly mode. All push button switches are working and all leds work. The pitch bend and modulation wheels both work. Both LFOs (MG1/2) are working on all waveforms at all rates.

Cosmetically the synth is in good condition. The metal casework and front panel are clean and legible with no dents and only minor wear. The factory particle board wooden sides suffer from fragility and are worn at the corners, ugly but purely cosmetic. The synth has not been modified in any way.

While the synth powers up and it is working it also exhibits the typical symptoms of a vintage analog synth coming out of long-term storage. The keyboard seems to have suffered the most during storage as there are now many intermittent keys. In addition most pots and switches exhibit audio signal noise when used. The synth will need servicing to be brought back up to spec. I am not a tech and it will be up to the buyer to determine any needs.” Click here to visit listing on eBay

“This is the one! All original knobs, buttons, switches, ends, etc. are present. In overall good condition- see pictures. Has some blemishes and scratches, but nothing obscene. Wood ends are dinged in places.

This unit is in excellent working condition. All notes and functions work as they should. It was serviced about two or three years ago by a famous Boston tech who used to maintain synths for the band the Cars, and who used to work for ARP. More recently (two weeks ago), I brought it in to be tuned and looked over. It has a clean bill of health and is ready for action!” Click here to visit listing on eBay

“I bought this from a collector who basically stored vintage synths and kept them in museum condition for years. I paid significantly more for this two years ago than is the average going price due to the amazing condition (see pix). The only marks it has are due to age but I’ve never seen one with all original parts in such great condition. It has never been toured and only kept in studio. When not used for recording this was always covered and protected carefully. It thus comes in truly amazing condition (all original which is very rare). It comes with the original 1982 manual and I will also include one of my large super secure hard Gator cases (with wheels). Just a note that the Gator case itself is well used (see pix) but is perfect for housing and looking after this synth.” Click here to visit listing 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 visit listing on eBay

“A very flexible and fun synth. Other cool tricks up its sleeve include chord memory and an effects mode in which oscillators have a variety of ways to be synced. The built-in arpeggiator and sequencer can run all 4 VCO’s at a time or cycle through each voice per note!” Click here to visit listing on eBay

“Purchased it 2 years ago on eBay, it’s amazing synth with lot of character and unique sounds but I’ve moved completely ITB six months ago and selling all the gear that I haven’t been using since.

Please see pictures and video about synth prior to bidding, synth has several issues from previous owners:
1. Four keys have cigarette burns
2. Pitchbend doesn’t return to center. I don’t know has it ever been returning or not.
2. MG1 action is swapped. I guess t’s because original owner has connected MG1 to midi-board with wrong polarity. I was using it as it is but it’s sounds like easy to fix.
3. Some pots are scratchy (volume, cut off, resonance) – it’s 30 years old synth.”

“Up for auction is a used KORG Mono/Poly Analog Synthesizer. This unit will need to be serviced! Cosmetically, this synth could use some love. The wood panels show many marks and one side is slightly separated, two keys are broken, one knob is broken off and missing, another is bent but knob is intact. All lettering and metal parts look good but could use a cleaning. Functionally the unit seems to work okay, as shown in video link below, except for one key is not responding. I make no guarantee as to the functionality of the synthesizer beyond turning on and making sound. ” Click here to visit listing on eBay

“Unkle I meant to say my monopoly which my uncle owned from new about 30 years if I can recall he was very much into electronics and saw one at a music store in London and painstakingly saved up for it monthly as it was a lot of money due to at the time this 4 oscillator pure analogue signal no digital guidance to alter the sound so it’s pure and moves giving that analogue tone not how they are mimic now as the Ines claiming to be analogue now are not or there are very limited as they use digital components to home in on the oscillators path so they do not drift or give the movement that pure analogue synths were made 30 years back so I’ve been told by a professor that the tones of true analogue paths have to be true analogue no digital control to make the signal rock stable which is not the point when you buy an analogue if that time any way it has been kept in perfect condition and the Korg alluminium case with the big logo on it which has housed it for many years and it works as it should and is a dream to look at anyone who comes to buy this will not believe it is 30 years old it looks like it’s just been made and the plugin that Korg released does not come close to the sound as I made a match and it very different check the YouTube of mark doty putting it through the pase and you’ll be shocked how it’s not more known only selling to give the money to his grandson as my unlike passed away 3 years ago” Click here to visit listing on eBay

“I am reluctantly selling my Korg MonoPoly analogue synth because “you never play it anymore” and “it’s taking up space”. This is true, however I will miss it when it is gone and perhaps it will get more use with a different owner. It has plenty of life left in it!

It is in very good condition, however it is over 30 years old so some of the pots crackle when you turn them. The keyboard has had it’s contacts cleaned so the keys are very responsive.” Click here to visit listing on eBay

“Up for auction is my Korg Monopoly. I’m having a clear out and as all my music stuff has been sitting idle for a few years, it has to go. I’m starting the auction at a reasonable price but be aware these are rare and the price will climb I would recommend you put in a good bid if you want it.

Visually the synth is in good condition considering it is 35 years old (See Photos)

Everything behaves just as it should apart from the odd key doesn’t always trigger and some pots are a little scratchy when turned. These problems are due to this synth not being touched for years, I have already found some problematic keys are now working perfectly again after playing it for about an hour. If you want to service it you can easily fix these issues, but I would just see if they sort themselves out because it’s well known that they generally disappear after a little playing.” Click here to visit listing on eBay

“This vintage Analog synth is a hands down classic. It’s design and layout is quite unique amongst vintage synthesizers. My unit has been well taken care of and preserved, kept in a smoke free studio, never gigged or left my studio, & recently serviced with two pots rebuilt by hand (checked thoroughly by Advanced Musical Electronics in Los Angeles, a 400.00 servicing). Functionally it’s excellent, everything works, and the body is in amazing condition for its age. The rear corners of the wood sides are worn, the only visible sign of long age. There are a couple marks under the white keys, shown in photos, all minor wear. The metal chassis is perfect. Lastly, the plastic Effects button cover is loose and came off. Nothing is broken underneath button cover. All in all this synthesizer is in excellent shape, especially considering its 35 year age.” Click here to visit listing on eBay

All keys are clean and aligned and contact correctly.

The unit was tested today and the synth is working as it should be: 100% functional and the tuning is rock solid.

“KORG MONO/POLY Analog Synthesizer that works great! This synth has been a friend for years and has amazing sounds that are super easy to tweak to your taste. All knobs, switches, and control wheels are fully functional and don’t stick. The wood panels are slightly dinged and have a few chips and dents from it actually being played. This has been used in a non smoking home studio for the 20 years that I have had it. The last pictures are of a function check where the sound is clear and EVERY KEY PLAYS. This is a fully analog synth and as such, it does need to warm up for a few minutes to keep in tune, but once you learn to use a real vintage synth there is nothing that comes close. The full board will be carefully packaged so you get it in one piece and functional.”

“NOW, I could kick whatever clown decided to paint the outer three panels white.
I mean, maybe they had a virus ti polar and a jd-xi and needed their other synths to match the all-white scheme? Who knows.
Maybe you love it. At least they didn’t paint over the front panel.

And the knobs, and the sounds are all great. Everything works 100%. Please bid accordingly.

Tested & working great. Comes with manual and case.”

mp ” Vintage Korg Mono/Poly Synthesizer with light FLIGHT CASE in excellent condition. Recently serviced to original specs by Switched On in Austin, TX (see pictures of work order/documentation). OWNERS MANUAL and SERVICE MANUAL included. I am the original owner of this synthesizer and have owned it for 33 years. In all those years, I have done my best to take great care of the instrument. I’ve made the decision that it’s time to move on to new instruments and must let it go.

The instrument is in better shape than any typical instrument of its age – it is very clean! The guys at Switched On in Austin, TX were impressed by it’s cosmetic condition! It looks and plays great! There’s minor dings on the corners of the woodgrain sides near the bottom. It originally had rubber feet on the bottom of the unit that I removed at some point so that it would sit flat on a keyboard stand – those are missing. There’s one key that’s been broken and re-glued (see picture). This is a only a cosmetic problem. All keys play perfectly since being serviced!” Click here to visit listing on eBay
