Moog MG-1

“Here we have the very last of these little monsters in our inventory. Cosmetically it looks great, however the interior was found to have sustained some rusting on the bottom of the frame and case pan from an unknown cause.
The rust has been removed and the unit has been cleaned up a bit but could really use a thorough going over throughout by a more expert hand.
All knobs and sliders respond sonically, however it has the following issues:

There are 4 keys that fail to make sound (labeled w/ post-it notes). The other keys appear to work normally.
One of the copper contacts has been bypassed with a small wire at some point in it’s history, apparently from a previous key failure.
The power cord has a break in the outer insulation but the inner cables are intact and the machine powers up and still works even in it’s current condition.

I believe the unit is fully restorable for someone who knows a little more about these things or someone who just wants to tinker with it and has the time and effort. Or even use it as a fully equipped parts supply if you have another one.
So, due to the condition we are offering this little Moog at a very discounted opening bid. Sold as-is to the highest bidder.” Click here to visit listing on eBay

“Realistic Concertmate MG-1 Synthesizer (Moog).

You are bidding on a Realistic Concertmate MG-1 synthesizer. These were built by Moog for radioshack and were sold in the early 80s.

This one is most certainly not 100% condition as it has lost a few slider covers and the sliders themselves will crackle a little, but this synth can still produce some incredible sounds that you won’t hear anywhere else.

There are pitch and trigger inputs on the back which work as cv and gate (these have been tested and work fine).
It has phono inputs (not through the filter) and outputs and a headphone output on the front.
Internal power supply and supplied with appropriate kettle lead.

This would be great as a refurbishment project or as I have done for many years – sequenced and sampled the synth for some incredible sound loops. The sound is massively unstable (in a good way) and just sounds vintage and alive in a way that modern analog synths just don’t quite capture.

Refurbished models go for between £500-800 at the moment, but to be clear this unit with all the various crackles and missing pots is not 100% perfect and the starting price reflects this. Please take into account the description and watch the video before bidding.

I want you to be aware of the nature of this quirky and at times noisy synth. I also want you to be aware that this is an oportunity to get an absolutely mad sounding synth that doesn’t quite sound like anything else.” Click here to visit listing on eBay

“Moog Realistic Concertmate MG-1 synthesiser. Classic vintage Moog tones, oscillators and filters. Used but in good condition.
Owned for years, but rarely used. As far as I can tell the only issues are the G and G# keys sometimes producing a delayed response, hence the lower price. Some signs of wear (see photos). Delivery with UPS 1-2 business days unless collected in person.” Click here to visit listing on eBay

“Selling my vintage 1980 Moog/RadioShack MG-1 Concertmate analog synthesizer; s/n 2463. Original owner, bought it new in 1981 in Temple Hills, MD when I thought that I had musical talent (I don’t) so was just me noodling around on it for all those years. Has been kept on display in my office for the last 20 years; non-smoking controlled environment. As far as I can tell, every knob/switch/slider functions as designed and sounds good, no crackles or pops from the knobs and sliders, which move smoothly. All keys clean, smooth and responsive (I’m not a musician, so I don’t know how to tell if there is a problem with the response other than “press a key, sound comes out”). Don’t see any evidence of major foam deterioration. Cosmetically excellent, no blemishes, dings, all knobs and sliders present. As this synth is 41 years old, it would certainly benefit from a professional cleaning and tuning however it is playable right out of the box.

Yes, I have the original box but it is in very poor condition having been stored in less than ideal conditions (see photos); fortunately the synth wasn’t in it during that time. I do have the foam blocks as well. The synth will be sent in this box with a much sturdier box around it. Original manual plus addendum included as well.” Click here to visit listing on eBay

“1980’s analog synth, very good condition considering the age. all sliders and knobs still present. Powers on and is still very functional, though some of the sliders and toggles are inconsistent due to the original insulation deteriorating, and hindering their function. Would likely need some cleaning/restoration to be fully “stage” ready.” Click here to visit listing on eBay

“But the Tone generator 2 which is the 2nd Oscillator is not working.
Despite the OSC2 not working it is dreamy creamy sounding synth with a clssic moog sound with plenty of scope. Can also be bold and harsh if needed.

I have been using it to record just using what is working on the synth, still sounds great.

Although a mono synth it has a poly section on it that can be mixed with the oscillator and bell ring modulator sounds so the synth can be used to play chords.”

“Moog | Realistic Concertmate MG-1 Analog Synthesizer. Condition is Used. This MG-1 is in good working condition , totally checked all toggles and sliders and every thing is working other than a few sliders seem a little stiff compared to the others but does not affect it’s performance as far as sound . some of the slider knobs are cracked and I used mini rubber bands to hold them together and they are replaceable. two sliders knobs are not original. if you look at the picture there is a slight bend on the case in the back bottom but is very minimal. And the reason I am selling is because it’s been in my hallway closet for a few years and I have other interests. The RCA jacks and headphone jack were also checked out.” Click here to search for synths on eBay

“Moog | Realistic Concertmate MG-1 Analog Synthesizer.
VERY GOOD Condition

Um, I LOVE this beautiful machine. I just need some cash and this is the last valuable item I can sell.
As soon as I have the money, I’ll buy another one. It’s a MOOG! And it was sold by Radio Shack!
And the Radio Shack manual refers you to Kraftwerk, Brian Eno and David Byrne, among others.

AND. I’m including the ROSETTA STONE, the Original Manual (a bit tattered) which gives you all the “settings” to create “Footsteps” or “Lasers” or “Talking Robots” or “Drums” or “Clarinet”. Plus, a couple blank pages to mark your own brilliant settings. Seriously, the manual unlocks this machine, even for an amateur — where you can begin with one of these settings and create new sounds modulating off their starting points.

This machine is in Very Good Condition, but note two things on the photos:

1. Six of the sliders are missing their plastic knobs — these are not necessary for performance + can be replaced (buy a dozen!)
2. The Back Right panel plastic has a chip — you would barely notice unless I pointed it out; again, doesn’t effect performance

Works GREAT. Sound GREAT. Perfect for recording or stage use.” Click here to search for synths on eBay

“Moog Realistic MG-1 Synthesizer Excellent Serviced. Condition is Used.

I inherited this synth and spent over $300 having IC’s replaced and the overall unit serviced recapped and bright back to original glory .

Sounds awesome .

I’ve been running it with no issues over 6 months however recently the lowest F has started periodically not responding. I spoke with the repair shop and they believe this is be a minor issue with the contacts .

Otherwise excellent and holds great tuning .”

Great sounding and rare synth from the 1980’s. Bought about 10 years ago and shipped over from the US (US/UK Power Adapter not included), and has been kept in the same condition ever since and to be honest has hardly been used in my ownership.

RCA Outputs haven’t worked since I got it but the headphone out at the front works absolutely fine.

Sold as seen and no returns or refunds”
