Realistic Concertmate MG-1

Realistic Concertmate MG-1 Image

This is the very source of cheap Moog bass! It is a lot like the strap-on Moog Liberation in its design and architecture and also looks and sounds very much like the Moog Rogue. The 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 cheap 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 divide-down 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.

Here is a table highlighting some of the differences pointed out by a user between the MG-1 and Rogue.

I was lucky. I placed an ad a couple years ago asking if anyone had a "small-sized synthesizer" for sale. I was really looking for a portable keyboard (Like a CZ-101 or Bass Station) to use while travelling. Instead someone offered my an MG-1 for $100 (I'm in Canada). Of course I jumped at it and the result is one of my favourite solo synths. It's not a bass machine like all the kids seem to want, but it just has a great vintage sound, much more fluid and organic than most of my other synths. Run through a cheap little Joyo analog delay it makes my ears happy.

Ben: There is one available from Paul's Boutique in Toronto (with whom I am not affiliated -- I just happened to be looking his up after seeing the listing) for $649 CAD right now. You can contact them through their website if you're interested.

I bought one of these in 1980. Paid $700 for it. Recently brought it out of the closet only to hear that the sliders and knobs don't work well - probably cost me a fortune to fix it. My loss.

Where can I buy one of these for a legitimate price? (Under $700)

I've just bought one at a ridiculous price (way, way too much for many people) but after watching all of the videos by Automatic Gainsay I decided I would rather have this than the Moog Rogue.

The last time one was on ebay it was for about £800 but I paid half that although I would much rather have paid less. I will post here how I feel after it arrives and I have played it.
