“This MOOG MG-1 Concertmate vintage analog synth is in immaculate condition but if you look closely at the photo there is a single biege mark on the first E key and one or two others are slightly discoloured. It was bought from new in the early 80’s and has hardly been used hence the reason for selling it.

I will atempt to field any questions you may have but there are some great examples of this synth in action on youtube and technical info available on the web.

This item is for collection only and I am situated by Birmingham International Airport, West Midlands. PLEASE DO NOT BID IF YOU ARE UNABLE TO COLLECT – NO REFUNDS.” Link

“Absolutely nothing wrong with the synth, everything has been checked out and it’s working perfectly. There should not be any dust in the sliders, if there is this is a quick and easy fix – all keys working properly.

Realistic was Radio Shack’s brand, but in 1981 MOOG made this synth to be sold in it’s stores, which is why it has the super warm and fat sound that makes it so desirable today. It features the infamous 24db/oct Moog filter, 2 Oscillators, an LFO with a ‘Sample-and-Hold” function, a polyphonic ‘Organ’ setting, ring modulator and more. It also has CV/GATE control so that it can be used with other synthesizers and drum machines, an essential feature not found on other similar consumer-marketed synthesizers.

It is one of the most affordable ways to enter the world of both monophonic synthesizers and MOOG synthesizers, but it’s also a unique synthesizer with a sound of it’s own. It’s really hard for me to let this one go, it definitely has a sound that I can’t get from my other synthesizers.” Link

“This is a cleaned-up and improved Moog Realistic synthesizer. The condition is better than new as it has been professionally modified.

The insides have been thoroughly cleaned and all the sliders replaced

New thermal coupling compound underneath the VCO ICs for better thermal coupling to the thermistors (better pitch stability)

Replaced all the electrolytic capacitors with new ones of same or higher voltage rating,

Recalibrated the synth per the service manual

Synth can now be triggered externally and used as a filter for external audio

RCA jacks removed and replaced with new Switchcraft ¼” jacks for: Audio Out, Audio In (to VCF/VCA), Gate In (positive voltage trigger > 1V, a more common standard in the synth world than the Moog S-Trig), VCF CV In

Attached power chord replaced with 3-prong IEC connector (easier to transport, easier to store)

Replaced the red LFO LED with a bright blue LED

Added ‘Sync Sweep’ functionality

Switch added to adjust the Envelope Generator to sweep the pitch of Oscillator 2. When the two oscillators are not sync’ed, you get Osc 2 pitch ‘swoops’, but when they are sync’ed, you get very cool metallic dynamic timbre changes.” Link

“This Realistic Concertmate MG-1 (serial # 1858) synthesizer from the mid ’70s was designed and built by Moog Music for sale in Radio Shack stores. It has all Moog circuitry, filters, oscillators, and envelope generators. Essentially, this is an everyman version of the Mini-Moog that was (and still is) widely used to create the synth sounds heard in recordings of the day. This unit produces all those classic sounds that Moog lovers have come to expect from the brand.

This unit is in excellent condition. I used it only in an in-home setting, and infrequently. The exterior is in near-mint condition, with no dings or scratches. I even still have the originial box (or what’s left of it), which I’d be happy to include. Unfortunately, I’ve lost the original owner’s manual, but discovered that it’s available as a download online. It was never taken on the road, or exposed to the wear and tear of live performance. I’ve had this keyboard checked out by a qualified technician, and while not “restored”, it has been thoroughly tested and all functions (filters, envelope generators, mixer, etc.) are in fine working order. All knobs and switches are original. The only modification this machine has is that the brown foam that covered the circuit board has been removed to prevent its breaking down and affecting the operation.

While this keyboard is in excellent working condition, as a vintage item I offer a return guarantee only if on receipt the item differs significantly from the above description.” Link

“Moog/Realistic MG-1 Monophonic Analog Synthesizer

Up for bid is a Moog MG-1. This one works perfectly, but the cosmetics are not perfect – I’d say a 7.5 out of 10. There’s some slight cracks in the plastic overlay panel, some nicks and bumps, and a tiny chip on the back left of one of the plastic side cheeks – pretty unnoticeable.

All keys, sliders, pots, and switches work cleanly and clearly. I’ve checked out all the functions and everything works correctly.

I’ve performed the following maintenance/improvements:

* Cleaned out the horrible foam that destroys the sliders,
* Replaced all the sliders with new ones from Technology Transplant,
* New thermal coupling compound underneath the VCO ICs for better thermal coupling to the thermistors (better pitch stability),
* Replaced all the electrolytic capacitors with new ones of same or higher voltage rating,
* Recalibrated the synth per the service manual.

I’ve also made several modifications to this unit; most of these are very basic but very useful:

* Removed the silly RCA jacks on the back
* Replaced those jacks with new Switchcraft ¼” jacks for:
o Audio Out
o Audio In (to VCF/VCA)
o Gate In (positive voltage trigger > 1V, a more common standard in the synth world than the Moog S-Trig)
o VCF CV In
* Removed the tattered ‘Realistic’ label on the back panel
* Replaced the attached power cord with a more convenient 3-prong IEC connector (easier to transport, easier to store)
* Replaced the red LFO LED with a bright blue LED
* Added ‘Sync Sweep’ functionality

That last modification is something that the MG-1’s sister synth, the Moog Rogue, had, but was left off the MG-1. Here I’ve added a simple switch to the left cheek panel to allow you to switch the Contour (aka Envelope Generator) to sweep the pitch of Oscillator 2. When the two oscillators are not sync’ed, you get Osc 2 pitch ‘swoops’, but when they are sync’ed, you get very cool metallic dynamic timbre changes.” Link

“This machine has been carefully serviced and a friend of mine I’m training did a lot of the actual work. Let me introduce Mike Smith (yes..I know it sounds like I’m making up a name just so I can have an alternate ebay account! But no Mike and I actually went to High School together in Corvallis, Oregon! He’s lived here in Montana for a little longer than me and he has a background in …well his bachelors in Geology. I’m training Mike to turn his caveman like instincts that he once used to crush rocks and the like…. to a more loving, gentle occupation of servicing these precious pieces of history! I decided to post this first listing for him to show him how ebay works. I’ll be carefully supervising his work for some time so feel confident that you are going to get the same kind of reliable synth from him that you will get from me. We’re going to try the name ’smithbailout’. )

Anyway this unit is sounding awesome. We lubed the sliders and cleaned all controls and dealt with improving the looks a bit. There are some small scatches around but at any distance it really looks great! The main issues are just cracks in the overlay thing. You can see the worst one that we did a little touch up on in the pic. The nice thing is..the adhesive seems to hold it down really well and it’s not trying to peel up or anything. So like I say at any distance the thing really looks just fine and electronically it’s superb. Mike meticulously cleaned all the little dust out around the key contacts even.” Link

“The Concertmate MG-1 is a synthesizer produced for Radio Shack by Moog in the early 1980’s. There is a lot of information about this synth on the web and if you don’t know what it sounds like you can even check it out on YouTube. As you can see it comes with the original manual and a stack of sheets that show what settings to use for different sounds. It sounds great and is in good condition! ” Link

“For sale a Moog Realistic MG-1 analog synthesizer totally restored and modified to increase the power of this great synthesizer.

The MG-1 was manufactured by Moog under the brand Realistic and the Moog Rogue was just a rebuilding of this synth ( the schematics and components are almost the same ) but the MG-1 has some features that make it superior to the Moog Rogue. In comparison with the Moog Rogue the Moog Realistic MG-1 has a Ring Modulator, individual modulation rate for VCO and VCF , individual wave selector on VCO1 and VCO2, individual octave selector on VCO1 and VCO2 , polyphonic section.

The main features of this synth are :

* 2 VCO with Saw/Square wave ( VCO1) Saw / Pulse wave ( VCO2 ) and sync
* Noise Generator
* 1 VCF , 24 db/Oct Moog Ladder filter ,( can be used as Sine wave Oscillator with really good tracking)
* 1 AD/ASR envelope
* 1 LFO
* Ring Modulator
* Fully Polyphonic section
* Glide

These are some of the works that I made on this synth during the restoring / modifying process ::

* General cleaning inside and outside, keys….
* Cleaning the famous sticky foam
* All the sliders and switches have been changed for new ones
* The three potentiometers have been cleaned internally
* All knobs have been changed
* Take it off the old RCA connectors and changed them for Jacks 1/4″
* New Thermal Grease on the Tempcos and Power supply
* PCB cleaning
* The synth has been modified to increase the signal/noise ratio, now the synth has louder out ( without any distortion at maximum volume )
* Added Audio IN to the filter ( now you can filter external signals)
* Added Filter CV In to control the filter with external signals like ADSRs, LFOs from modular synths etc
* Added a Gate IN because it has S-trig IN , now you can use it with almost any Midi to CV converter and it’s more easy to control with all analog sequencers.
* New internal dust protection
* The synth has been re-calibrated
* The synth has been converted to European voltage ( 220V ) and comes with European plug.” Link

“This is a Concertmate MG-1 Analog Synthesizer.

Made by Moog Inc for Realistic Corp, it incorporates Moog’s patented chips & stable oscillator technology for those famous gutsy phat sounds of the MiniMoog & SonicSix .” Link

“Up for auction is a Concertmate MG 1 Realistic Synthesizer By Moog music! Item is in great condition, except missing knobs as seen in picture. Love this Synthesizer great for any Synth collection!” Link

“selling my mint MOOG REALISTIC CONCERTMATE MG-1 SYNTHESIZER. everything is there. Includes original manual.” Link

“The Concertmate MG-1 Professional Synth was built for Realistic (Radio Shack) by Moog Music. It is analog and can certainly produce some interesting sounds. I have only used digital synths but I will answer any questions the best I can.This keyboard was bought by my uncle and then passed on to me. Everything works on it and it sounds great. It has two small chips in the keys that can be seen in the pictures. Other than that it is in excellent condition. Included is the original box, owners manual and RCA cables.” Link

“This is an amazing instrument, but I’m a guitarist and need an amp. I’m hoping the sell of this will provide the funds.” Link

“he MG-1 was built by Moog for Realistic (Radio Shack), and was designed specifically for the home market. Very basic and easy to use, this is a nice affordable way to get your hands on Moog sounds!

The MG-1 is a 2-VCO monophonic/polyphonic analog synth with a genuine 24dB/oct Moog filter, however the overall sound is thin. On the MG-1, the VCOs are referred to as ‘Tone Generators’. It can produce sawtooth, square and pulse waveforms, and the oscillators are detunable and syncable. A simple ASR (attack, sustain, release) envelope called ‘Contour’ can be applied to both the amp and the filter. The LFO section provides triangle or square wave patterns as well as Sample-and-Hold. Additionally there is a simple Ring-Mod effect called ‘Bell’.

Unique to the MG-1 is a slider on the far right side of the keyboard which controls the volume of a simple 10-voice polyphonic organ sound. This feature makes it at least a little more versatile than the Rogue. There are RCA inputs and outputs (the input is routed straight to the output for playing along with music from your stereo system) but no external speakers as in most other home marketed synthesizers. There is also no sign of Midi or patch memory on the MG-1. It is used by Peter Gabriel, 808 State, Remy Shand, and KMFDM.

CONDITION: Excellent, I have had this ion my bench and in my Shop and it performs perfect it does show a little sign of its age but nothing of any real consequence. This is a real clean unit nothing broken or Moded at all. I would rate it a 9.3.” Link

“Up for bid is a vintage Realistic Concertmate MG-1 made by MOOG for Radio Shack. This keyboard is an excellent source of classic MOOG sounds for less money. Everything from cheap sci-fi effects to huge concert style bass. I also used this unit as a tone generator to calibrate my Ampeg SVT bass amp. (Think front row concert subs chest compression)

This keyboard is used (at home only-low hours) but in excellent condition. All sliders function as designed without noise or scratching. The knob is missing from the RATE slider. It has been replaced with a soft plastic cap. It still works fine.” Link

“moog concertmate mg-1, works perfectly, some slight cosmetic damage, including a chipped key, missing tone source nob, and a few missing screws that need replacing, all can be easily fixed, A really great piece of equipment.” Link

“The MG-1 is one of the most under-rated analog synths. I have owned several of these over the past 10 years and they never let me down. It a lot of ways the MG-1 outshines its Moog siblings. It has a polyphonic section, which passes through the characteristic Moog filter, it has a ring modulator that can be mixed in with its two sync-able oscillators, and it has a flexible modulation section. Plus it is really small and lightweight, making perfect for gigs or conserving space in the studio.

LZX Industries performed some simple modifications on this MG1 to make it more useful. The RCA jacks on the back have been replaced with high-quality 1/4″ jacks. The audio input is routed through the filter now and there is a filter CV input. This MG-1 can be used as a standalone filter or interfaced with a modular synthesizer and other gear, like Moogerfooger pedals. A V-trig input has been added, making it easier to sequence the synth or play it from other synths that use the v/oct and v-trig standard. The BEST mod on this MG-1 is an additional switch that disengages the LFO on Oscillator One. This allows you to take better advantage of the sync and “bell tone” features by modulating one oscillator and not the other–a sound you cannot get from a regular MG-1! ” Link

“For sale the Realistic MG-1 made by MOOG music. The MG-1 is a direct copy of the MOOG Rogue.

It has original user manual written in German, Dutch and French.

This synthesizer is in really good condition and can be discribed as “like new”.

Due to vintage status no returns accepted.” Link

“Hello. You are bidding on a Vintage Realistic MG-1 by Moog with original box and packaging, dust cover, 2 Monster RCA – 1/4″, and stereo Y adaptor. This unit is essentially a Moog Rogue in dimestore clothes. Don’t let the Realistic name fool you this is a quality synth. Everything works perfectly. Keys are nice and straight and level and all work. There’s a little scratchy-ness on the contoured cutoff slider but that’s the only issue I can find. It’s been in semi regular use since I bought it 2 years ago and it’s always been reliable. I never used it to gig with just at home and practice. It’s in nearly mint condition – it’s exceptionally clean and I’ve always kept it covered when not in use. I’m sure if you’re looking at this listing you already know what this is and what it does….but in case you don’t there’s a lot of great demo’s on youtube.” Link

“This Moog / Realistic Concertmate MG-1 Synthesizer has treated me well for years. I removed and retained the RCA jack board and installed a 1/4″ output and a 1/4″ input that feeds an external audio source to the filter. The old jack board will be included with the purchase of the synth. I demonstrate the filter modification using an Epiphone Les Paul in the Youtube video embedded below. This feature really enhances the capability of the synth.

The synth works and sounds great. The only functional issue I ever encounter is that sometimes the power switch doesn’t engage. Almost without exception, it works when I switch it off and then on again. Some contact cleaner in the switch assembly would probably fix this but it never really bothered me, so I never did anything about it.

The only other issues with this synth are cosmetic and minor. Describing them makes the effects seem more significant than they really are. However, I will address and photograph them so there are no surprises upon delivery:

The slider caps and knobs are a little dinged up and some of the silver inserts have fallen out (the ends now painted silver).

There is one replacement slider currently on the cutoff. It offers a better grip than the originals (I don’t have the original cap).

The power cable’s outer sleeve has split where it connects to the chassis.

Apparently the right panel had fallen off in the past and was glued back on. White residue is visible along the interior edge (as photographed near the rear 1/4″ output jack).

There are also some scratches and dings overall, but nothing that compromises the synthesizer’s aesthetics in my opinion.

Those are all the issues with this otherwise wonderful instrument.” Link

“Have had this for about 20 years and regrettably must part with it.. The synthesizer made by Moog and sold by Radio Shack !

Because you’re here you know what this is and what it does…many sound samples of the MG-1 can be found on the net.

Mine is in particularly nice all-original condition..all of the keys are even, no scratches or wear on the control panel, all sliders and knobs travel smoothly and all sounds function as they should.. Even includes the original cap for the headphone jack

PLUS…comes with the original box and styrofoam packing blocks !. have never seen another one of these with the box.

Also included is a spare chip KS-5823 Six Stage Divider..(frequency divider)….I had the MG-1 serviced a few years back by a Moog-trained tech, and got this extra part.

I will throw in the MG-1 Owners Manual and MG-1 Service Manual on CD (PDF file)” Link

“This is an 1980’s vintage Moog Realisitic MG1 Synthesizer. It looks in good condition. I powered it up and plugged into an amp and I got

some good sound out of it. All of the knobs and sliders are there and seem to work but I don’t really play the key boards so I don’t know

if I’m useing it to it’s fullist exstent. The volume knob is a little loose but still works.The 3rd key from the left didn’t work but may need to be cleaned

to get it goin. I’d suggest to clean the sliders and the keys but I’m not the man for that. This is a cool synth and I’m sure someone could put some

life back into . I’d keep it but I play the guitar not the key boards thats why its being sold.” Link

“For auction is this near mint MG-1.
Great moog bass and leads.
Basically it is a Rogue with added string/organ section, and internal power supply.
Really amazing little synth.
In exceptional condition and working perfectly.” Link

“Really neat little monosynth with some interesting modulation options. It’s supposed to be like the Moog Rogue, but spec wise, it seems more like a liberation without all the cool keytar parts. It has an added poly organ section that can be quite useful, whether it is beefing up the 2 oscillators on the monosynth or playing funky filtered organ chords. The condition is generally good and everything works & sounds great. The oscillator mixer levers are missing their caps, this doesn’t effect the operation of the keyboard.” Link

“Moog Concertmate MG-1 Realistic by Moog Music, vintage 1980 analog dual oscillator mono phonic keyboard. Great Pink Floyd sounds, great for hip hop bass lines, and even Doors sounds ala “Strange Days”. Very excellent cosmetic condition except for a couple of small scratches on the right side and one on the bottom, but the top where all the sliders and knobs are is super clean! All the keys are in excellent condition and every key works good. All the sliders and knobs function perfect with out any extra noise. There is a 1/4 inch jack output on the front and rca jack outputs on the back. There are 2 1/4 inch inputs in the back, 1 is a trigger input and the other is a pitch control. The trigger input can be used to plug in a guitar or bass or whatever, and the sounds that are in the keyboard can be triggered with whatever you plug into it. This was a trick used by many punk/art bands of the late 1970’s and sounds really cool. The pitch control input can have a volume pedal plugged into it, and with wah-wah foot action, you can go from deep lows all the way up to screaming highs with the movement of your foot. This is one incredible sounding little analog vintage synthesizer that will entertain you for hours with all the crazy sounds you can get out of it. Anything from FAT basslines to screaming leads to crazy helicopter sounds. Everytime you change a switch, turn a knob, or move a slider, you change the sound drastically. 1 really fun old keyboard!” Link

“The instrument is playable as it stands, and everything works, although it would benefit from some attention. The internal black foam turned to gunk long ago and has been cleaned out. Some of the sliders have been cleaned up and don’t have such a good feel as the others. It is possible to buy and fit replacement sets of sliders and switches, so this is not a big issue. The power transformer is a bit tired and may need replacing in the future. Like many old analogue synths, it takes time to warm up.” Link

“I have owned this synth for about 12 years. I purchased it from the original owner. It is in great cosmetic condition (considering it’s age). It has some light scratches here and there but really looks great otherwise. It is missing all the slider caps, but the 3 knobs are still there. All sliders/knobs/keys function. I can say that the tuning definitely seems out. I am not an expert on the electronics in synthesizers so all I can be certain of is that it does turn on, make sound/noise, and all the sliders affect the sound in some manner. some of the sliders are a bit dirty, but after you move them up and down for a minute they seem to clean out. I have been keeping this around for a converstion piece, but it is time to make room in my studio.” Link

“Today I am auctioning off my Moog Concertmate MG-1 analog monosynth. Cosmetically this synth is almost mint. Everything looks fantastic. I removed alot of the black stuff that comes inside of this era Moog stuff but some still persists. It is missing three slider knobs but replacements are easily found and in essence meaningless (you can move the sliders fine without it). The sliders could probably use a cleaning; they all move fine but the “peak emph” slider has a bit of static when moved. It sounds GREAT… There’s a lot of misunderstanding out on the net about this synth. It is essentially a three VCO analog synth with the 3rd OSC being divide-down polyphonic (yet limited to just square wave). There’s very few Moogs I’d put above this unit; I’d rank this one above the Source and the Prodigy. It also has a ring mod, cv/trigger in (you can purchase a box that will turn cv/trig to midi), and I modded this unit with an input allowing you to process audio through it’s 24db Moog filter (self-oscing!)” Link

“Up for sale is a vintage Moog Concertmate MG-1 analog synthesizer. This thing is incredible. It gets all the classic analog Moog sounds, and is great for insanely phat basses, screaming ELP-style saw leads, ambient pads, sci-fi sound FX, and pretty much everything else. You really have to play one for yourself, and here’s your chance. I really hate to sell it, but I have to scale down and I need the money, so my loss is your gain. All of the original knobs and pots are intact, and everything has been tested and works great. There are no visible scratches, scuffs, dents, etc. The oscillators are quite stable as well, considering it’s age.” Link

We do our best to describe things accurately and we point out when something is scuffed or flawed in any way. The close up of the keys shows the one scuff mark on the G key. The shots of the corner show that there are very small dings on the corner. Though hard to see in the pictures, there are a few of the original knobs that aren’t 100% cosmetically (mainly, the cutoff freq knob in the filter section). However, these are very small cosmetic problems and the unit really is in excellent condition. ” Link

” Up for bid is my Realistic Concertmate MG-1 Made by Moog Music. This unit has been babied and works perfectly.Some minor crackling on some of the sliders but can be fixed with spray cleaner. keyboard tracking switch is loose but still works. Cosmetically in great shape.missing two slider buttons. Used in recording studio.” Link

“Up for sale is my Moog MG-1. It is in decent shape, I’d say 7/10, and all functions work perfectly. Tuning is definitely a little whacky, but you get used to it! It is missing one slider cap, and some others are missing the little silver sticker. Other than that, everything is accounted for. I’m not sure if all MG-1’s have this or not, but there is a 1/4 output on the bottom right on the front of the keyboard, in addition to the RCA outs on the back.” Link

“This is one cool synth. All original. Nothing missing. Even includes the original owner’s manual and a copy of the Radio Shack receipt from 1983!” Link

#1040
Being sold AS-IS, was tested and dials and levers worked, sounds came out

on inside.” Link

“This is a great Realistic Moog MG-1 analog synthesizer in great working order!! Comes with hard-case!!
Calibrated by Health Club Music in Portland, OR.
It makes great bubbly Moog bass, sci-fi effects, polyphonic organ sounds, searing 2-oscillator leads and sync effects.
Best of all, it is compact and portable.
Physically beautiful condition except it is missing 1 slider cap.” Link

“Up for bids is a vintage realistic concertmate MG-1. The item is cosmetically beautiful, and, although it looks great to me, I would not say mint, because many people are bananas with the word “mint.” Nonetheless, this little bugger has served me well in the studio. It does have an issue that I’m aware of—I’m a guitar player, and a noise maker with synth, so there could be a minuet issue that I’m unaware of. The BAD: there are a 6 keys that do not produce sound—they are not stuck—they just do not produce sound(Low F#, G, C, C# Middle F#, G). This has not caused me any trouble—because I play in Protools, and I use the Moog for white noise/oscillator. THE GREAT: Good looking and great sounding—definitely shoot into sci-fi land. ” Link

“This auction is for a MOOG MG-1. The unit is in great shape, has all the keys, knobs, and slider knobs. Cosmetically very good. The only flaw is the power cord where it comes out, right on the back of the unit rubber has begun to crack and has started to frey. (upper left hand corner of photo you can see this) The serial number is 3649. It has spent the last few years in a closet but was used in a smoke free studio. Before I purchased he synth, it had been in a closet for years also. US shipping only. PayPal only. I usually send items with UPS but have used USPS also. Feel free to contact me for more information and photos. I’m going to miss this little guy!” Link

“Up for auction is my beloved Realistic Moog. This unit works perfectly. I have owned it for about 10 years and it has lived in my smoke free studio. It is a real analogue synth and is very fun and easy to use. It has always worked just great. There are no cracks or stains. All knobs & slides are original & fully functional.” Link

“I purchased this Concertmate MG-1 Synthesizer made by Moog Music for Realistic at a garage sale. I do not know much about how it is supposed to work but I played with it for maybe an hour to try to test it. It is not functioning perfectly so I am selling it “as is” and as described. It measures close to 20 5/8 inches long. It weighs a little less than 12 pounds.

Four of the keys on the keyboard do not produce a response when they are pushed. When I first tested it, only one key was not working but 3 more stopped working as I continued to play with it. The tones do not change or remain the same when I play different keys. I do not know if that is normal or not. I have not tried running music through it to see if maybe the keys are supposed to vary the tones that are run through it. Otherwise, I was able to make quite a few different and interesting sounds and it seems like most of the functions are working. I did not notice a change when I fooled with the polyphony slide but that might be only because the other settings where not correct for hearing changes. I tried using earphones and I tried hooking it up to an amp. Both ways yielded sound. I tried all of the slides and switches. To be safe, I will say most of them are working fine. There might be some malfunction that I am not able to determine. I noticed a little static when moving some of the slides. I noticed that something was moving when I turned it upside down so I opened it to see that what looks to me like the power supply was not anchored to the case because two screws are missing. I will try to buy those screws before the auction ends so that part can be anchored before I ship the synthesizer. I know what size to look for. If I do not find the screws, I will find some other way to be sure that it is not moving around when I ship the unit. To my untrained eye, the inside parts that I can see look fine and not burnt. Still, something might need to be replaced. Or , if we are lucky, only the wrong might be that connections need to be cleaned.

Cosmetically, it shows some moderate wear or use. There are three missing plastic covers for the sliders. Also, there are several very fine and short cracks in the board where the sliders and switches are. You can see what I am talking about by looking at my close-ups. There are some scratches on the sides of the case. It could use some cleaning. Otherwise, it is fine and as shown. My photos should give you a good idea of the general condition of this synthesizer.

I guarantee this item to be as described and represented by my photos. ” Link

“Moog Concertmate MG-1 Synthesizer! The Moog works except for the RCA output and their is no ground on the plug. Their are 2 knobs missing and a very minor bend on the bottom plate on one of the corners. Very minor though. The synth itself works great. This synth is a beast!” Link
