Moog MG-1

“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.” Click here to visit listing on eBay

“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 visit listing 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 visit listing 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 .” Click here to visit listing on eBay

“Moog Concertmate MG-1 Realistic Vintage Analogue Synthesizer

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” Click here to visit listing on eBay

“No reserve auction for a Realistic MG-1 synthesizer made by Moog. This synthesizer is not in working condition. When turned on, the power light will blink on for just a moment, and then turn off again. Fixing it is beyond my capabilities, and I’m moving my studio. Selling for parts/repair only. Again, this synth DOES NOT WORK, and will need to be repaired or used for parts.

This keyboard looks really nice, and all pieces are intact. Please inspect the photos thoroughly. A few notes: 2 of the slider knobs are missing their silver endcaps, and there is a little rust to the washers around the 1/8″ outputs, which did work just fine until the power issues. I purchased this keyboard in 2010, and the previous owner cleaned the foam off the circuit boards.” Click here to visit listing on eBay

“This is a modified piece. View photos for more detail. I’ve attached labels to describe the mods as best as I know. They are a huge improvement for this synth. Overall condition is good. A couple keys have small chips. The foam that goes around the knobs and switches circuit board has been removed. The mixer section sliders sound a little dirty. It tends to pick up noise in the added knobs if the volume knob is set too low, but the sound is clean if the knob is set higher.” Click here to visit listing on eBay

“Moog Realistic Concertmate MG-1 synth – vintage analog synthesizer in very good condition, see pics. All keys work, all sliders and knobs work. I used it to trigger it from a Eurorack modular, so CV/Gate input works great as well, stays in tune nicely. Big, fat, warm old Moog sound I can’t seem to replicate exactly with my Sub Phatty, but I don’t need 2 bass synths now. I recently opened it up to clean the grimy foam off, and upon putting it back together the far right key went askew; not sure what happened there, but the key plays fine. There is a missing silver decal off of one of the slider caps” Click here to visit listing on eBay

“I had this tested & the salesman said it’s not quite right.

Shout out to Kevin at C. A. House Music St Clairsville OH.

It powered up & played but I recall him saying something about a crossover slide.

I don’t remember all the tech lingo he mentioned but all the keys worked anyway.

The case is near perfect, no damage, missing parts or yellowing to the knobs.

Heck! I didn’t even see a scratch.

It may be something simple cause it’s in such fine shape?

Comes with the inst manual printed in 4/82.

Sold as-is with no returns.” Click here to visit listing on eBay

“Foam is removed and overall good condition. There are very small chips in the front of 2 keys. See photos.

This MG-1 has a lot of mods. I can only guess what some of them are because they are not labeled, however, I’ve included photos of the wiring to help you figure it out.

Here’s what I can tell you about the mods:

Rear RCA jacks were changed to 1/4″ and it’s now V-trig for easier sequencing.
The output volume seems louder than stock.
I think the detune slider has been changed to go down a full octave.
The switch on the left drops the keyboard down one octave.
One of the knobs on the left changes the 2nd oscillator’s pitch. I think it detunes.
I think the knobs on the right are FM for Oscillator 2 and PW/PWM for Oscillator 2 square wave.
The lower switches on the left and right route what’s happening on the knobs to the LFO. ” Click here to visit listing on eBay
