“This is a very nice vintage Moog Opus 3 synthesizer. This Moog is in excellent condition. As far as I can tell, everything works. It plays and sounds great. I am not a keyboard player, I play drums. But it looks to be all original, and works great. It has never been cleaned so I would think that the electronics slides and pots need to be cleaned. Wood sides have some scuffs, dings and scratches. This unit is a very desirable and collectible.Vintage Moog sound at it’s best. Comes with power cord.” Link

“Moog Opus 3 Synthesiser – serial number 2447 / 220v

I’ve owned this Moog since 1990 and between 1994 and around 1997 it was used on tour by a English / French band that are well known for their Moog associations.
While being used on tour it was serviced twice by the Synthesisier Service Centre in London for general services.
For the last 4 years it has been stored and unplayed. I am the manager of the band and not a musician but I have plugged some headphones in and all of the keys seem to work as do the effects.
As I can’t test the keyboard 100% this will be sold for spares and / or repairs
The keyboard is in reasonable cosmetic condition but has the following obvious faults -

* The attack slider on the Articulator is missing the knob and although the slider does slide it isn’t as smooth as the other sliders on the keyboard.

* The on/off knob on the Chorus is missing completely although the switch still seems to work

* There is a small piece of wood missing from the right hand side, next to the last key

Supplied with the power cord.” Link

“First off, let’s make this absolutely clear:
THIS KEYBOARD DOES NOT WORK RIGHT AT ALL.
That said, details follow.
T LEAST the following problems exist. There are likely more
The sliders need replacing; the switches need replacing.
Most of them still largely work, but they are not reliable at all.

Many screws and one wooden end-piece are missing as well.

The tone generators all work, and at least one note divider is likely out
Divider problems typically cause a set of notes (all the C’s, for example)
to disappear; This is a common problem in poly-synths and organs.

1. It’s a great restoration project, as it still has life left in it.
It works enough that I keep it around hopefully for restoration (but my Farfisa Organs and other Moogs keep me quite busy enough, thank you).

2. It’s still an excellent noise-music generator, because the classic Moog filter works 100%. This thing still produces gut-wrenching lows, and a mere flick of a slider sends it into painful screeching, ear ringing highs. BTW, I am not responsible for the hearing damage these models can cause, and I am not joking AT ALL.

3. Parts, of course!

4. This is an EXCELLENT candidate for (careful) AC circuit bending. It can kill you, though, because most circuit bending is done using DC ( battery-powered) devices. Still, it can easily be altered for use as a stand-alone Moog filter, for example, and most of the keys still work.
——————————–

Seriously, I like these keyboards a lot, and I always have. But, sadly, I have too many corpses and projects to keep it around;
I want desperately to fix my Moog Concertmate MG-1, and I can get the parts I need by selling this one.
It could live with surgery, but euthanasia and organ donation are definitely options.

WARNING: If my other keyboards were in a hospital room next to this, I would seriously be
concerned about staff infection or maybe flesh-eating virus. In fact, I am!
SOLD AS-IS, of course.
There will be no returns, of course, as I have listed it’s extensive problems.” Link

“Moog Opus 3
Analog Polyphonic Synthesizer
Amazing Condition w/ Power Cord!
100% Fully Functional
Check out our feedback and Bid w/ Confidence!
Moog Opus 3 specs:

* Polyphonic analog synthesizer
* 3 OSC: (String, Organ, Brass)
* 2 VCF’s (1 for Brass and 1 for String with switchable high, low, or band-pass filtering and resonance)
* VCA (level and panning for each OSC)
* Keyboard: 49 keys (no velocity & aftertouch)
* Stereo Ouputs

Review:
The sounds are broken up into 3 categories: Strings, Brass and Organ. Strings and Brass have their own separate VCF filter sections, the Organ section has none. The Opus-3 also has 2 sound outputs for an early stereo effect with panning! It’s a colorful little synth with clearly laid out sliders and is fairly straight forward. It has classic analog Moog sound quality and is a great source of some string and lower octave techno-organ sounds.

Functionality:
All knobs, switches, sliders and outputs working and pristine cosmetic condition – Fully functional.” Link

“he Opus 3 is a fully polyphonic string/brass/organ polyphonic instrument with a 49-note (C-C) keyboard- and has 3 main instrument sections- Strings, Brass and the main Organ section. These are not preset, but offer a wide array of sounds that you can shape and build for yourself. Sonically, the Organ is very rich and warm sounding, with a 6-slider variable tone section, the Strings section features FM modulation and a cool sounding chorus for more ambient or prog sounds, and the Brass section features the ability to do more hi-pitched squeals and bass pulses. The Opus 3 was also a big part of Stereolab’s trademark sound for many years. All buttons, switches, sliders are present & intact and working. This model features FM modulation,2 VCF’s, one for a brass section and one for the string section (with switchable high, low, or band-pass filtering and resonance) and two rotary wheels for pitch bends and modulation control. It features stereo outputs and each of the brass, string, and organ sections can be panned. The rubber feet are still properly intact. The power cord is included with this auction. The unit is in great shape cosmetically, and has been in a smoke-free environment for the duration of my ownership.” Link

“I’m selling my Moog Opus 3. This synthesizers has been in my smoke free studio and was very babied. The marks were made by the previous owner. It’s missing the organ slider knob and one of the feet, but I do have the owner’s manuel. Everything works perfectly.” Link

“For Sale : Moog Opus 3 Analog Synthesizer in Very Good Condition. I purchased this synth about a year ago and it has the Diabolical Devices upgrade where they replaced some of the LED with blue which looks extremely cool – especially when the LFO is going with the lights out. Check the pics .. Overall cosmetics, this unit is very clean – I’d say about a 9/10 .. with (very) minimal scratching on the sides and the face is super clean .. keys are straight and it is a fine example of this synth.. All functions work on this synth except one, and that is why I brought it into the shop to have it ‘tune up’, (see receipt) to the tune of $140.00 and check out the issue with the Brass section .. To my ears when I pan the Brass section to the hard right, it emits a sort of ‘distortion’ to the brass sound .. it is very easy to get around this by just panning left or reducing the volume in the Brass overall .. but when I got it back from the shop – they thought it sounded ‘normal’. I usually would just blend the other sections up and pan L and its no problem. But I take good care of all my synths, so I am disclosing everything to the best of ability .. Other than that – the synth plays and sounds really great. The warmth and organic sounds from synth will suprise you .. If you are curious about a band that features the Opus 3 heavily – I would check out Sleepy Eyes of Death. It’s all over their albums.” Link

“Vintage analog Moog Opus 3 synthesizer!!! These were introduced in 1980 and I would have to think this one was manufactured in 1980 as it has a very low serial number (249) making it one of the first produced, which increases its collectability. Just back from checkup/cleaning/service–everything works and good to go! Plays and sounds great with the HEAVY sound anlog synths are know for! All of the original keys, knobs, sliders and tips are there as is often not the case. Has some scratches in the wooden cabinet as expected for an older synth.” Link

“Up for auction is the vintage Moog Opus 3 synthesizer. This synth is in perfect working condition, and is in very excellent cosmetic shape. This Moog features a beautiful dark walnut stain wood cabinet, which is also in excellent shape.

The Opus 3 is a string/brass/organ polyphonic instrument with a 49-note (C-C) keyboard. It features a noisy chorus and 2 VCF’s, one for a brass section and one for the string section (with switchable high, low, or band-pass filtering and resonance).

The Opus 3 features stereo outputs and each of the brass, string, and organ sections can be panned. The rubber feet are still properly intact. All buttons, switches, sliders are present & intact and working. The Mix to VCF slider is still present and 100% functional. The power cord is included with this auction. The Moog Opus 3 has been used in a smoke free studio environment. Selling Opus 3 as-is.

Not pictured is an instruction manual and tech spec manual, which I will include with this auction.” Link

“Up for sale is a used Moog Opus 3. This item is in working order. However, the string oscillator is not very loud. I would venture to say it not operational at all – however it does create a very low volume sound. Cosmetically, what you see is what you get. It does have stickers on the keys – I am helping a friend sell it – I am not sure what they are for. Other than that it is missing 2 nobs which can bee seen in the pictures, I did my best to capture that. The top can also be removed with ease. Other than that everything seems to be in place.” Link

“The Opus-3 is one great little synth. It was designed by Herbert A. Deutsch from Hofstra University who originally nudged Dr. Robert Moog into building synthesizers and later served as director of sales & marketing for Moog Music. Herb also wrote the owner’s manual. The sounds are broken up into 3 categories: Strings, Brass and Organ. Strings and Brass have their own separate VCF filter sections, the Organ section has none.

“Moog Opus 3 Synthesizer! READ CAREFULLY!! I have had this in my studio for about 5 yrs.Last time i used it (2 yrs. ago), it worked great! I tested it out before i put it in this auction and the strings and chorus were not working! i was told the pots just needed to be cleaned. i am really not an electronics guy so i am leaving it up to whoever wants a good deal with what i hear is minimal work. Comes with heavy duty flight case and stand!” Link

“Classic analog piece, making sounds, missing a few keys, about 4 keys don’t make a sound. Modulation works, sides need reattaching,seems mostly working. Physically is in a bit of rough shape, fix it, use what you can of it, strip it for parts, you decide.” Link

“ie bieten hier auf einen originalen MOOG OPUS 3 Synthesizer. Dieser gehörte meinem EX Mann und war Teil seinesMusikstudios. Ich habe keine Ahnung von Technik und kann deshalb nur Angaben zu dem machen was ich damals so über diesen Synthesizer mitbekommen habe.ER hat ihn für 1500DM gekauft.Ich weiß nicht ob dieser Synthesizer heute noch etwas wert ist oder ob er gesucht wird,deshalb diese Auktion.
1. Es ist ein polyphoner Synthesizer.(soviel weiß ich noch)
2. Ich habe ihn eingeschaltet und für mich klingen die Sounds nach Orgel und Trompeten,bin halt kein Tontechniker.
3. Optisch hat er Gebrauchsspuren am Furnier,die Tastatur funktioniert einwandfrei und es sind alle Knöpfe und Regler vorhanden.
5.Im Lieferumfang ist der Gerätestecker enthalten!” Link

“THIS IS THE KEYBOARD MANY OF US ALWAYS WANTED.

SUPERB CONDITIONS.PLAYS LIKE THE DAY I BOUGHT IT IN 1977.

I CAN’T SAY ENOUGH ABOUT THIS KEYBOARD,EXCEPT AMMAZING.

THE ONLY THING IT NEEDS IS A PLAYER THAT KNOWS WHAT THIS BABY CAN DO, AND MAYBE A COAT OF VARNSH TO THE WOOD CASING.” Link

“Everything Works, Shipping will Vary.” Link

“Up for auction is a Moog Opus 3 is great condition. There is nothing missing or damaged. All knobs, slider caps and colored tips are in place. Everything works the way it should. No scratchy pots or sliders. Nothing feels worn out. A few minor dents and some slight wear on the wood here and there. The front is in fantastic shape. The Opus 3 has 3 analog filters, stereo output and pitch bend. No other string synth has this. It really sounds great. I have owned several other string synths and I think this one is the best. Everyone who comes over gawks at it–It’s like studio bling.” Link

“Vintage 1981 Moog Opus 3 Polyphonic synth. Great Shape. Works Well, and i have relied on this as my bass warrior for a while. All VCOs work and there is no noise or problems at all. This moog is nice because it was one of the only ones that was polyphonic and reliable (unlike the Mg-1). I used it primarily for bass and i feel it does that well, but this one is good for just about anything. Comes with a nice hard shell case and the original manual. Serial number is 3662.” Link

“Great Rare MOOG OPUS-3 Synth. It’s in great working condition & a fun synth. It’s been well taken care in the studio, but have to sell to make room for other gear. Feel free to ask any questions. Good Luck!” Link

“Up for auction is the Polyphonic synth the Moog Opus 3! This unit is fully functional and has been serviced by an old Moog technician from the factories. The initial foam put in upon the release of this unit HAS BEEN REMOVED! YOU READ THIS CORRECTLY!! Moog originally put a foam in the unit to prevent dust and other things from entering the unit. Over time this foam would turn into a tar like goo. THIS HAS BEEN REMOVED. I also took the time to get it serviced and clean up all the sliders. This unit functions like a charm. It comes with the original owners manual. I am selling this unit because I am not a keyboard player and am planning on purchasing a new guitar amplifier for my most current music project. Since I never played this very much, the unit is in fantastic shape.” Link

“This Synth is used. Brass switches broken off- bought it off ebay like that. 3 Keys on the high end broken but still play. This synth makes cool sounds. I am not a synth player or expert but will try and answer all question to the best of my ability. Model # 339A” Link

“Moog Opus 3 vintage polyphonic analog synth. Likely the cleanest Opus 3 you will find! Check out the pictures for yourself.

With 2 easy fixes, this could be a collector’s piece. 2 issues this synth has are: 1) The wood sides are faded and could use a re-staining. They are in great shape otherwise (no major gouges or chips). 2) The brass “16’ 8’ 4’” switch is broken. Seems like it’s not too difficult to install a new one from searching the web. It’s a typical 3 position switch, found in other synths.

Purchased 15years ago and it’s been in storage ever since. I’m no expert but it seems to work great – every switch and slider alters the sound. Sounds great!” Link

“Hello and thank you for checking out this auction! Today I am selling my classic vintage Moog Opus 3 synthesizer(keyboard) after owning it for just about six years. Naturally I bought it on ebay and although I paid a lot for it back then, it was money well invested as I got many hours out of this puppy and today I have some recordings I am proud of by the use of this very keyboard. When I received the Moog in the mail there were a few minor cosmetic problems and those same issues are still with this keyboard today! However, I want to stress that in no way does it affect the sound this baby produces. As you probably know already. if you are a serious musician and you know where that true “vintage” synth sound comes from, you know it has to come from a Moog like this one. And I have always maintained that the actual instrument is always better than a computer generated sample, although a few companies do come pretty close to recreating that special Opus 3 tone. So going back to the only flaw this keyboard has, if you look on either side of the instrument, you will notice it has a wooden frame that supports and surrounds it, keeping the keyboard together in one piece. Well, on this one the wood is beginning to barely come loose and this will need to be fixed in the future. The keyboard is strong and it will have no problems with its playability and sound so don’t trip out! Trust me, when you turn this puppy on and let it warm up(most of these old fart synths need a few minutes to rise to full sonic capability) you will be wearing a smile as you hear that Moog tone through your headphones or your external monitors.” Link

“For sale a MOOG “OPUS 3″. This synth was purchased in the late 80’s by a friend of mine for a boat cruise gig. At the end of the trip he stored it in his loft and there it remained until a couple of years ago when I bought it.Condition is very good with light marks on the wooded body. The layout is basically three sections.Strings, organ and brass. These can be infinitly blended using modulation chorus and voltage controlled filters. There are a few other parameter adjustment controls like articulation (attack and release settings) and VCF Mode etc. All works as it should apart from one problem. The pitch wheel seems to be set incorrectly because to attain tuning at A 440 the pitch wheel needs to be rolled to it’s farthest point (sharpest in pitch under normal conditions) away from the player at which position it remains and is then in tune( the wheel is not sprung loaded to return to center as some pitch wheels are). So this is not really a problem apart from loss of the ascending pitch facility. The pitch wheel can be used only to fall away from a given concert pitch, but not above. Hope this explains the fault clearly. I think this could easily be corrected by a technician (if you know of one) so that the instrument would then be 100% fully operable and as new. Having said all of that this Moog Opus 3 is a lot of fun and great for live work due to it’s relatively easy operation and clear panel layout and lableing. Great to tweak one sound with the other two remaining unchanged.Infinite sounds available. The output is mono and then two outs (left and right for stereo)all on 1/4″ jack. It has a sustain pedal option as well also 1/4″ jack..I have the operators manual but can’t locate it at the moment. Will find it before the auction ends but, failing that I will post it to the winner should there be one! ” Link

“Here we have a MOOG OPUS 3 Vintage Synthesizer from the early 1980’s. I had this synth listed a couple of months ago but a non paying bidder did not follow through with the transaction…so I am finally getting around to listing it again. It is serial no. 5323 and seems to work the way it should. I plugged a set of headphones into the output jacks and could hear the sound of the keyboard, although it was not very loud since the outputs are line out and not headphone out. The wood parts do have some mars and scratches as you can see by the photos, but all the knobs and switches are original and color coded. There is one key on the top end that appears to have a cigarette mar on it (as seen in the last pic) but other than that all the keys are nice and bright. ” Link

“f you are looking at this you already know that you want it. I won’t lie and say it’s got some indie rock history, i bought it from the original owner on craigslist about 4 years ago. It was a lady in her 60’s, and she had it on a quaint little table next to her piano, and told me her and her husband used to do piano with string accompaniments. I have used it on three tracks since then, i don’t pull it out too often, so I want to pass it on to someone who will use it more.

Everythings works excellent but (i make it an effort to be 100% truthful in my auctions to make for smooth transactions, and you can tell by my feedback), the pan controls on the stereo mix section are a little scratchy when you pan, but once you have it where you want it its great. (a little contact/lube spray should help it, i just haven’t done it).

The only other cosmetic thing is the graphic overlay is peeling up a little on the corners, you can glue it back down if that matters to you. You cansee it in a few pics. Pics are of the actual unit for auction. ” Link

“Up for sale is a vintage Moog Opus 3. These are pretty hard to find nowadays. The unit is in good condition and seems to be in perfect working order. All sliders and dials work fine.” Link

“PLEASE NOTE THIS IS A PICK-UP ONLY ITEM. SERIOUS BIDS ONLY PLEASE. NO BIDS ACCEPTED OR CONSIDERED FROM OUTSIDE THE UK. I WILL NOT DELIVER OR SHIP UNDER ANY CIRCUMSTANCES. IF YOU CANNOT AFFORD THIS ITEM AND CANNOT PICK IT UP, PLEASE DO NOT BID. MANY THANKS!
The instrument has very minor cosmetic wear but is in full working order. It has only been used in a live situation three times and not for 11 years. Since 1985 it has mostly sat unused, sometimes for a year or two at a time, as my musical career was intermittent at best and I’ve only hung on to it for sentimental reasons. It has been kept in a smoke free environment. But I have played it recently and it sounds the same as ever. It will be supplied in a vinyl case which has seen better days but is useful for carrying the synth about. As I say, it’s a scarce synth but to give you an idea about its provenance, it was used by Kraftwerk, Stereolab 808 state and others.” Link
