Moog MG-1

“Im sure you know what this is if you’re looking but here goes.

Here we have my vintage(?) 1981 Realistic Concertmate MG1 its and analog mono synth, with a few other interesting features. It was sold by radio shack and Tandy here in the uk back in the day as I recall, but it was made by Moog Music.

I love this thing, it sounds great and does what you would expect of old mono synths and a little bit more quirky stuff as well, its got a polyphonic organ type tone as well as a bell tone which is kind of like a ring mod you can mix in the amount of each you want on the faders. you can even set the mode for it to drone on on its own continuously…..

Its in good working condition and has been in the studio and never gigged, it was rigged up to a cv & gate converter midi interface and performed admirably.

This is a real reluctant sale as time aren’t good, I would love to keep this one but its being sacrificed to keep some of the other stuff.

I’ve also got the manual which in itself is a great early 80’s read.

Its just the mono synth for sale not the synth its sitting on…

I’ve not seen a working one of these about for a while.”

“In good working condition.

I bought this years ago and it looks like the previous owner has added a mod to the vcos. It doesn’t seem to do much apart from affect the pulse width slightly.

The internal transformer has been replaced due to the original one buzzing quite loudly. Some sockets have been removed from the rear, but the output socket is working fine.

Ideal project for someone wanting to restore/modify further as these things can be turned into analog monsters.

Otherwise, it seems in good condition.” Click here to visit listing on eBay

“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.”
