Synthfind

“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

“In very good cosmetic and function shape. All the slidders are there but some have the top shinny sticker missing. I bought this new in the 80s.” 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

“For sale is a Moog Realistic MG-1 synth. Absolutely perfect condition. 1982. Two oscillators with sync & detune, one producing either a Square or Sawtooth waveform, with the other producing either a Pulse or Sawtooth waveform. One low pass filter/VCF, that can use the envelope generator, has limited keyboard tracking, and is capable of self oscillation. Limited envelope generator with variable attack and release, and a switchable sustain (no decay). Oscillator 2 can be tuned independently or synced to oscillator 1. Noise generator. Ring modulator (called “Bell Tone”). Polyphonic oscillator. This oscillator is routed through the filter, but not through the envelope generator or LFO. LFO that can modulate the oscillators and the filter using a triangle, square or random waveform Portamento (called “Glide”) External Control inputs for pre-MIDI CV/Gate.” Link

“Up for bid is this used Realistic Moog MG-1 Synth. I bought this at an estate sale so I don’t know much about it. I have tested it and it appears to be in great shape. Some of the black keys show some wear, but the rest of the unit is in great cosmetic condition. ” 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 runs 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.

This MG-1 has some simple modifications 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, interfaced with a modular synthesizer or other gear, like Moogerfooger pedals. A V-trig input has been added, making it easier to sequence the synth or play it from gear that uses the v/oct and v-trig standard.

This synth looks and works great. It was completely serviced when the modifications were performed. It has some small scratches on some of the black keys and there is a small crack in the plastic on one of the front bottom edges–neither are very noticeable.” Link

“You are bidding on a vintage 70’s MG1 Realistic Synthesizer by Moog Music. It is the Concertmate MG-1. I have been the only owner of this item, bought it new in ‘72, it is still . This IS the ORIGINAL MOOG. Plug this in and you wont be able to walk away from it for hours. Look closely at the pictures to see the variety of controls and editing options. All keys work, due to its age the output consists of to RCA’s a left and a right. Excellent condition, several small scratches on 2 of the keys, missing one very small equalizer knob(see photo far right EQ), doesn’t effect playability.” Link

“This is a virtually spotless vintage Moog Synthesizer originally sold by Radio Shack. All knobs, switches and sliders are present and functioning. All keys are in perfect condition. Note there is the additional custom made cover (lovingly made by MOM), hence no dust, no smoke. This is in pristine condition and is sold as is, in all its glory. It comes with the original manual. I just fired it up in my studio and it works perfectly. A shot of tuner cleaner on a few of the sliders is all it needs. ” Link

“You are bidding on a vintage Realistic Synthesizer by Moog Music. It is the Concertmate MG-1 This unit has been owned by us for many years and still fires up, however; due to its age, it is beings sold AS IS. If you do not agree, please do not bid. It is about 21X11. I am adding a few more pics. It is missing one of the slider covers on the far bottom right but I am sure this could be obtained.” Link

“Super clean and 100% working.” Link

“synthétiser moog en parfait état livré avec une interface midi cv gate. le mg1 est un synthé signé moog pour la marque realistic.Il est en tout point similaire au moog rogue mais avec une section polyphonique en plus c’est un très bon synthé spécialisé dans les lead et les basses. je m’en sépare à contre coeur car je déménage à l’etranger. il possède 2 oscillateurs,une section polyphonique, un noise, et un ring modulateur (qui n’en est pas vraiment un) il y a un glide, un lfo, une enveloppe très sommaire etc… pour plus de renseignements me contacter.” Link

“UP FOR AUCTION IS A MOOG REALISTIC MG-1 ANALOG SYNTH SYNTHESIZER NICE . IN GREAT SHAPE WORKS FINE . PLEASE LOOK AT PIC FOR MORE INFO .COMES WITH EVERYTHING YOU SEE IN PICTURES ONLY.” Link

“In Good Condition a little ware on the keys one slider knob missing but slider works. Power Cord Included” 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

These will also work in a Prodigy, Source and Rogue as well as a few others

“this is a replacement keyboard out of a moog MG1. this keyboard was pulled and was on standby for a repair that never ended up happening years ago. i do not have anyway of testing it at this time and is being sold as it and used. last time it was hooked up all keys worked but that was years ago. it is not missing any parts to the keyboard or the wiring and circuits.” Link

“Offered here by TIMEWARP MUSIC is a Realistic Concertmate MG-1. This particular unit is in excellent, nearly flawless condition. The unit has been working on by our keyboard repair guys and is in 100% fully working order. 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

“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

“used item. i have been the only owner of this. bought new at radio shack in mt. sterling ky in 1984. it works well. missing one slider cover that i lost the other day while pulling this out of storage. i no longer have the manual. if it gets bids in the first day or two, i’ll make a youtube vid of it and place it here. as usual, shipping is to lower 48 states, no warranty, no returns, excessive neg feedback email me first. selling this because i need the money and i don’t use it.” Link

“This is a vintage analog synthisizer sold by Radio Shack under the Realistic brand name. It was designed and produced by Moog Music for Radio Shack. It is sold as is. Its in fairly decent condition. Everything works except the noise generator. It has been repaired a coupld of times, one to replace the tone source tuning pot and the other time to fix a non-working divider chip. Also, the black foam eveyone talks about has been removed.” Link

“I love this keyboard and really hate to part with it. It is in great condition cosmetically and operates perfectly. I had the foam stuff that turns to gunk removed. That stuff was a bad idea to have put in there. If you are looking for an MG-1 it is a good idea to have that stuff taken out. It is a huge hassle to get rid of it and can be quite expensive to have removed. Please email with any questions and I will be happy to answer them in a timely manor. ” Link

“Original MOOG MUSIC(USA) Model 42-4000 Synthesizer by Realistic. Wow, you never see em like this, made by MOOG Music & sold by Radio Shack, this one’s in fine shape, works perfectly & one owner(non smoker) clean,carries serial#3454. Not a scratch, unfortunately box & manual tossed. Fine example!” Link

“Used MOOG MG-1 analog synthesizer in good shape. Tested and working smooth. All keys and sliders work good. For its age this synth looks and sounds pretty darn good. This synth does have a few cracks in the plastic housing around some of the switches. The cracks are simply a result of the old age of the plastic, and are on the surface level only and do not go all the way through the housing – see pictures. These cracks do not affect the playability of the synth at all. The synth is still very solid. Additionally two strap buttons have been installed on the sides of this synth so it can be worn like a guitar – a keytar, I never used them myself, but hey, whatever floats your boat.

Moog Concertmate MG-1 is an analog synthesizer made by Moog Music and was distributed by Radio Shack under their “Realistic” brand name. The MG-1, on its surface, appears to be a “Realistic” branded synth, but it is, for all intents and purposes, a genuine Moog Synthesizer. The Moog concertmate MG-1 analog synthesizer has the following features:

– Two oscillators, one producing either a Square or Sawtooth waveform, with the other producing either a Pulse or Sawtooth waveform.

– One low pass filter/VCF, that can use the envelope generator, has limited keyboard tracking, and is capable of self oscillation.

– Limited envelope generator with variable attack and release, and a switchable sustain (no decay).

– Oscillator 2 can be tuned independently or synced to oscillator 1.

– Noise generator.

– Ring modulator (called “Bell Tone”).

– Polyphonic oscillator capable of 8-note polyphony. This oscillator is routed through the filter, but not through the envelope generator or LFO.

– LFO that can modulate the oscillators and the filter using a triangle, square or random waveform

– Portamento (called “Glide”)

– External Control inputs for pre-MIDI CV/Gate.

– Independently tunable polyphony section” Link

Radio Shack version of the Moog, and it actually sounds good, from before the time they started selling cell phones. “This is in Excellent/Very Good Condition for its age with just a few small marks/blemishes. Was always well kept and with its all due respect. Just a couple of the knobs have just a tad and I mean just a tad bit of scratchiness, but a little contact spray should clear this all up. Thats it, otherwise your looking real good on this RARE great sounding anlaog synth! Enjoy!” Link
