Moog MG-1 Concertmate

EASY AS PIE! And fun too!
I played it on our CD called ASCENSION, on a tune called "The Hanging Tree" and it sounds dang cool. We added a bit of delay to fatten it up.

Very simple but a fun synth, for sure.

It sounds damn bitchin', but is not very expresive. But that didn't bug me, I'm used to synths with very little "Expresive" features like aftertouch, etc.

We never had problems with ours.

I like Radio Shack, they have nice batteries for sale there.

about as easy as it comes. Very easy to understand layout. If you've never used an analog synth the MG-1 is a perfect synth to learn on, though you'll need to relearn terminology. Tone source = oscillator, bell = ring modulation, etc.

I gig with mine and find it very easy to use live, provided you write down all your settings for each song AND I also suggest you take along a guitar tuning pedal (I use the Boss pedal) and check your tuning with it.

Mine did not come with a manual but Yahoo has an email resource group for the MG-1. I downloaded mine through there.

The MG-1 is your basic analog monosynth with the usual features:
- 2 voltage-controlled oscillators with a choice of pulse, triangle and square waveforms and four octave settings (osc 1 has -2, -1 & 0 settings for your bass; osc 2 -1 through +1 for leads.) oscillators will sync (the rough tuning for osc 2 becomes a pulse-width setting)
- 1 voltage-controlled amplifier with an ASR set-up (though you can also set it for max sustain and let it drone forever)
- the famous patented Moog 4-pole 24dB voltage-controlled filter that will self-oscillate if set properly
- an LFO with square, triangle & sample-and-hold settings (will module the VCO or VCF)
- a mixer section with white noise generator
- CV input for gate and note
- programmable glide

It has a couple of features somewhat unique for synths at the time:
- a 10-note divide-down organ tone ("polyphony" on the mixer) that takes a beating from other reviewers, but I like mine a lot. The keyboard itself has two triggers under each key, one for the synth and one for the organ. So you can use all three oscillators together.
This feature was included by Radio Shack reportedly because their customers would really miss playing chords.
- ring modulation ("bell" on the mixer)

It is missing two key features found on most analog monosynths:
- a modulation wheel (though the modulation slider is located in a reachable place for you to use it and not really miss the wheel)
- a pitch wheel (this you can't really get around unfortunately, but I hardly use a pitch wheel on my other synths so it's not missed.)

It has a master tuning knob and a master volume knob. All parameters are easily accessible via rocker switches and faders. There are stereo RCA outs and ins on the back. The outs aren't hot and are noisy, so I notmally use the 1/4" headphone jack on the front. The ins bypass the filter and are meant for playing along with your favorite albums. There are resources online that tell you how to change those RCA's to 1/4" jacks, eliminate the noise and run the ins through the VCF. I've not done that yet but hope to at some point.

No MIDI but since it has CV ins a Kenton kit will take care of that for you.

The sound versus price is certainly the key to the value of the MG-1. While it isn't a MiniMoog it certainly can dial up Mini-esque sounds, from deep bass to expressive leads, pads, percussion, FX and sounds in-between. I've had the opportunity to run my MG-1 side-by-side with a Moog Rogue and a MiniKoog Model D. The MG-1 and Rogue are virtually indistinguishable (though I prefer the MG-1's layout to the Rogue's) and I found I could get a lot of the same sounds from the Mini on the MG-1. It wasn't a scientific test and I'm sure that had we REALLY analyzed the two that the Mini wwill outperform the MG-1. But a working Model D will set you back at least $2500. You could buy four or five MG-1's for that price.

If you are into really deep synths that yield continuous sonic surprises the MG-1 is not your synth. If you are looking for that Moog sound that software and VA's can really only get close to, then pick up an MG-1. Don't let anyone tell you this synth is "thin" or not really a Moog. Open it up and you'll see Moog stamped on the VCO and VCF cards. Although Moog built this synth for Radio Shack, Moog liked the design so much that they took the prints from the MG-1, altered them slightly (ditched the polyphony & ring mod and added pitch/mod wheels) to manufacture The Rogue.

I've gigged mine for several years without major issue. As I've mentioned above I do use a guitar tuner with mine since I do get some drift throughout a set. I usually try to let the synth warm up for 10 minutes. After that you need only adjust the tuning once or twice a set.

You will read about the horrendous black foam turned to sludge inside these synths. It is true. Mine has not been cleaned (I hope to do that at some point) but I've not noticed any noise from the rockers, faders or knobs as a result. Still, I love my MG-1 and want to keep it as long as I can so I will clean it out. There are online resources that will walk you through the process.

It is plastic and the keyboard isn't as fast as a modern board is, but I've dropped mine a time or two without issue.

From Radio Shack? Ha!

Online? Lots of forums, mailing lists and informational websites will help you trouble-shoot a lot of issues with the MG-1.

Overall there are few synths I would trade my MG-1 for. It gives me basically what I'm looking for everytime I play it. I'd love to have a second one to use live strictly for bass drones or with the CV/MIDI kit with a sequencer. They are relatively inexpensive, expressive and reliable. If you want a closer facsimile to the Moog sound than samples, software and VA's can get you then track one down.

MG-1
NO PRESETS. this is OG. you need to know what yr doing. once you've messed around with it for a while you can really make some weird sounds. good luck keeping it in tune.
i have nothing but fun when i'm playing this thing. full size keys are awesome.

Monophonic, with a simple/lo-fi polyphony slider. this thing has the classic moog filter and in the mix section a slider labeled "bell" this is just a ring modulator, but cool.
there is no velocity on these keys. just push them and it sounds. i've seen one that was retrofitted to have midi capabilities, but if i was going to spend money on this thing, i'd get some expression pedals or ribbon controllers for the glide.
it has 2 VCO's called "tone generators" and a few glitchy sounds are hidden in all this things sliders and switches.

this is the keyboard you want if you are looking for cheap moog sounds. think fat bass, psychedelic swells and CLASSIC moog filter. a bit of glide gives this that cool oldschool hiphop lead sound. i think of it as more of a studio tool than something for a live situation. hook up a delay unit to this thing and you could have hours of spaced out psychedellia!!! the Hi-Fi mainstreem guys will tell you that this thing sucks but DON'T believe them. its perfect for yr garage band or in any sort of indie/lo-fi situation.
if yr recording, i recomend you run this thing to an amp and mic it. the direct signal is really noisey.

this thing goes out of tune. if you already have alot of keyboards/instruments in yr live setup i'd reccomend you just buy a microkorg or something. but, if you are going to devote all of yr time to the mg-1 it can work in a live setting. since there are no presets, you have to know exactly where everything goes. if you just want it for basslines or something it is great. just expect a bit of set up time to dial in for each song. mine has only been slightly restored and i've never had much trouble with it.

i don't even have a clue. i doubt that radioshack still has any info on this thing.
but, i've had good experiences calling casio for old manuals and stuff so maybe...

THIS THING IS RAD. plug in effects pedals, push those filter sliders and it takes off. i've had mine for almost two years, its fun, and classic. i've definately played better synthesizers, and presets are really convieniant, but my mg-1 is close to my heart. it makes every sound i've wanted it to and it looks really cool. if and when if breaks down, i'll probably just go digital cause in a live situation i just have too many other instruments to worry about without trying to tune and reset the mg-1 after everysong. if you want to be oldschool and mess with all the settings, this keyboard is for you. if you are a working musician and reliability is key, i recomend something else. perfect for the studio.
i payed alot for mine. i've heard stories about finding them at garage sales and thrift stores for 10 bucks, but with ebay setting second hand retail prices, i doubt you'll find one for this cheap anywhere but in the boondocks.

This synth has no presets, being 100% in your face analog. Editing a patch is as simple as reaching for a control and tweaking it; no stuffy menus here. Some controls have odd names, such as 'bell tone' instead of 'ring mod'; I believe this was intended to make it easier for Joe Citizen to understand what everything does. A very rewarding little synth to play with.

This synth is Monophonic, however there is a third oscillator (simply called 'polyphony') which provides ten notes worth of a simple organ tone; this feature is useful only in some situations. The keyboard feels reasonable for a budget synth; full size plastic keys, no velocity or aftertouch.
There is no expansion provided from the manufacturer; MIDI can be retrofitted using third party kits.

Excellent for bass, good searing leads, simple effects. This synth could probably be used in almost any genre. Did I mention it was great for bass? It also has excellent bass. All analog controls mean excellent tweakage; it really is fun to use. It has a lot of character and warmth. The filter is excellent, it is very squelchy. The sample and hold LFO wave is a gem.

Don't know how reliable this is, but when I got mine, it was covered in all sorts of gunk, and it still sounded great. A couple of the sliders are a bit scratchy, but that can be fixed. Build quality leaves a lot to be desired; the plastic is strong but a little too flexible for my liking. I guess that's realistic for you.

Meh. The only support you'll get is online (but it's probably better than dealing with Radio Shack!).

What a great little synth - it's my first fully analog synth, and now I've taken the plunge into pre-midi gear, I want more! I own two Juno 106's, a TX7 and an MS2000B, and this is the best of the lot. The bass that comes out of this thing is so chunky you can carve it. I'd seek to replace this if it were nicked or busted, but I might consider finding a mightier MOOG instead. I was fortunate enough to receive this for free, but I would recommend purchasing it to anyone who likes synths or just wants cheap, beefy sound (albeit with a 2.5 octave keyboard); especially if you've never played with a fully analog synth before. Definately the most fun you can have for this price.

No presets; just have to move sliders to obtain a tone. Mine came with both manuals. Although they are both a little water damaged, they are informative especially if it's your first analog synth (it's my first). The service manual has all the schematics but is the most damaged of the two which kinda sucks because it has a nice drawn out pcb layout for when you need to replace parts, which I'll get to later...

All I can say is, this is a Moog and deserves the name. There are 6 different sections to this synth: modulation, tone source 1 and 2, contour, filter, and the mixer. There is a slider for polyphony but it definately is "phony", because it is like a square-wave toy organ sound that as you move up the slider you can hear all the notes respond, but if it's mixed in with your tone sources, the tones are only mono so it doesn't realy sound good at all - not useful for anything of today. There is no midi, but threre are instructions online on how to make it possible. This was manufactured by Realistic but I'm one of the lucky ones to own such an awesome machine - it was made entirely by Moog in 1981 and in the RadioShack catalogs for '82. Basically it's a Moog Rogue with a little less features, but more people seem to like this model better.

Well, it's analog, so expect it to sound analog. It sounds great if you ask me. In the manual they give you patch settings for instruments but they're kinda boring. It's better to just tweak it out slowly on a boring Friday night and discover all the potential it really has for such a limited synth. The keyboard action is kinda stiff, and the keys feel like glass because they're made out of really smooth hard plastic. But it's not touch-sensitive and has no aftertouch or anything so it really doesn't matter. The tone sources can be sync'd together and sound much fuller and better when they are. I just got mine today and I was already making really deep bass hits and growling analog leads, so I can imagine what I can make when I'm actually spending some time really paying attention to it! Overall, sounds like a really smooth analog, and beijg my first Moog I can't say "it sounds like a Moog" but I'm sure it does.

I'm not sure about this yet... I mean, it seems to go out of tune a little when I turn it on from the previous time, and the casing except for the bottom is all plastic, though it's a good grade plastic. The casing is a bit wobbly though. You can't fault RadioShack for this either, because I played a Moog Micromoog and the casing on that is pretty flimsy too, and that's straight up Moog. Well, then again, so is this. I personally wouldn't want to take it out of the house for a gig but that's just me. But at the same time, if I'm aiming for a particular sound and bought the MG-1 particularly for that purpose, then I guess that would be the point. However, because it seems to go out of tune easily, I'd be annoyed if I had to keep tuning it all the time at a live show.

I'm told that Tandy still has the manuals for this and since my service manual is so damages I may end up calling to request one. But don't walk into a radioshack with yours because no one will know what it is.

If it were lost or stolen, I'd be upset but I'd probably move on and get a really nice Moog. This is a starting point for me, though I sure hope no one ever ganks it from me. That would really suck because I've been searching for one of these for a long time and finally have one. It wasn't easy, either. But all of the MG-1's were made with a foam liner over the sliders and pots and over time it degrades and turns into sticky jello foam. I didn't really think it'd be as bad as people say, but it is pretty nasty. Some of my sliders cut out and feel a little stiff and I know that the congealed foam is to blame. So now I have to spend the time to clean it out, but I'll probably replace all the sliders and switches anyway if I'm going to do that much. I like this synth and I'd like it to be playable for many years to come, so I feel it's worth the effort. But buyer beware, that this is a common problem and you most likely will have to do some cleaning up in there so it doesn't ruin anything else in the future. Overall, a great synth by Realistic worthy of the Moog name and a great addition to any synth rig, digital or analog. Can make those cool dance beats if you play with it, and can make spaceships as well!

I'm just following up on my MODs...yes, it came out better then expected, now the thing is rack mountable, nice big knobs (sliders are stupid, and they get noisy and dirty). I had to chop the circuit board in half and rewire, but the thing was suprisinging willing to agree to my hacking.

I'll be adding some new features soon.....

There was a reason I mounted the guts in a rack mount case and stuck a bunch of high quality knobs and switches on the front.

Try calling your local Radio Shack store and ask them if there is anyone there who knows how to fix a Radio Shack Concertmate 1.

I love this little guy......

It just doesn't get any simpler. All of the elements are within this synth. No software/presets/patches/programability. Pure analog. The manual is meant for the home hobbyist intrigued by synthesizers.

As mentioned before, an organ-ish polyphony. The Moog filter is killer! Outstanding for bass and all kinds of other foolishness. Got a neighbor that you dislike? Cook up a sound that makes your teeth itch and set the envelopes on "continuous".

I'll bet it can weave it's way into just about every style. It's a blast to play.

The only trouble I have had is with one of the frequency dividers going bad causing a few keys to not work. The excact I.C. is no longer available but there is a replacement. If yours is acting this way, don't despair. Google yerself and warm up yer iron 'cuz help's on the way. Oh yeah, the foam is a pain in the dorsal fin. Get rid of it and touch up all the connections for the sliders on the main board.

Yeah, Radio Shock refused to own up to the fact that in a by-gone era, they were the purveyors of this here fine synthi. Shame, shame. Lotsa info is out there should you take the time to look.

I'd be crushed if anything ever happened to it. It was a Christmas gift from my Mom to my Dad back in '82, so obviously it can't be replaced. In my estimation they are worth the 2-300 bucks they seem to be fetching on e-blah.

As easy as pie, if you can't figure it out you have some problems

Well, it is pretty old. no polyphony no midi no expnasion etc. but that is pretty par for the course for a true analog synth. One feature that is notably missing is the evenelope is only AR which makes it much harder to do bleeps and drum type sounds. Also real inputs would be nice to use that sweet filter on other sounds.

This synth sounds awesome!! The filter is goregeous and the oscilators are nice and dirty, esp if you detune them just a touch. The ring modulator makes some nice filthy tones and the ability to mix the 4 settings is good. This thing rocks for bass, blows my juno-60 out of the water

Mine is great and stays in tune really easy. I just started a new band (Joy Division, TransAm) in which it's the ONLY thing I play (sometimes I run it through a delay pedal which sounds VERY nice). nuff said

Uhhh I have no idea

If it were lost stollen or broken I would cry cry cry and then go on ebay and buy a new one. Although if I have a bit more money I would probably go with a prodigy (to get the features I said the mg-1 didn't have), but the mg-1 is small and easy to cary to rehearsal and gigs. So maybe i'd just stick with the mg-1 anyway!

C'mon now, it's a preset free analog synth. What could be more simple? It's only hard to use if you have no imagination.

For what it is (a late 70's, early 80's, budget monosynth), it's feature packed. Two main Osc's plus a third that gives a very wierd, cheezy quasi-polyorgan feature, ASR, LFO with truely random setting, AutoTrig (!!!)and those wonderful Moog filters.

If you want performance concert piano sounds from this synth, then yer a dumbass! For fat bass and truely bizarre wails, you can't beat it. It's the wolf in sheeps clothing; many folks don't realize it's a Moog and pass by.

The AutoTrig, combined with the kicking filter section and judicious use of the detune section is pure gold.

I must be very lucky, as this synth is rock solid; It stays in tune with no warm up. Balls on, every time.

It has needed a little TLC from time to time, but what can you expect from a 20+ year old, second or third hand keyboard? I'm handy with a soldering iron, so I've never had to send it out. My repairs have included:

*removing the old, rotted foam everyone has to.

*Hard soldering the voltage control wire from the main board to the keyboard section. This broke when I was servicing the synth; I nearly cried when my synth would only play 1 tone no matter what key I pressed. A quick look revealed a broken wire in the harness. It was easier to extend and solder it than to replace the whole damn 8 prong plug.

*The sliders. Ahh yes,those shitty sliders; a source of constant bitching among MG-1 owners. After some tinkering, I discovered however, that the sliders are in perfect working order. It seems that the particular pots on the MG-1 have mounting points that are active (as opposed to having seperate mounting tabs and electrical connections). I retouched all the connections with my iron (adding a bit more solder for extra beef) and lo 'n behold, every single slider is smooth and quiet now.

*The RCA connectors in the back are old, corroded and crackly; I'll replace them soon enough (maybe performing the audio input to filter mod at the same time)

If you call RadioShack's support and argue enough to actually convince their droid that they actually sold it, they'll find and sell you a Xeroxed copy of the manual for $25 bucks. What's the point?

There are plenty of info resources and repair services available on the net to keep your MG-1 humming along for years. A few kewl mods and midi upgrade are out there too; just Google.

If someone stole or broke my MG-1, I'd hunt them down and dig their eyes out with a rusty spoon.

Easier than a Korg MS-20 similar to a Arp 2600 series.

Very full, but even better with a more monophonic synth.

Very sturdie,dropped once, long distance transport couple of times just with in a year.built like a tank (tank made of plastic)

Did talk to people at Radio Shack.They said that they send them out for serviceing and it's $80(cdn) just for there servicing tech to look at it.

Very good for the price you will probally pay.

i mastered this baby in one sitting. understanding the layout is the easy part, making it sound unique and expressive is the challenge. this synth could not be any simpler and still provide such great tone.

no impressive poly here, unless youre recreating nintendo theme songs. mods will make it expandable, but i would never want to do that. to me, playing an analog keyboard should be done with the fingers, in true analog fashion. i wouldnt want more features, based on the applications i use it for, except maybe a pitch wheel.

i play this synth in a rock band and i basically play the keys with one hand and the sliders with the other. i have found that by using the mod and 2nd vco creatively, a wide range of sounds is possible on the fly.

well, i bought it in very good condition and i havent had a problem yet. despite my active playing style, ive only broken cables and stands. the synth keeps coming back for more. tends to drift out of tune live, but a pedal tuner is an easy fix.

limited to specialty repair shops, although demand for analog synths makes knowledge easy to come by. support is out there if you know where to look for it.

i wanted a simple analog synth that i could rock out on, and this baby delivers. i dont need a minimoog, id probably break it. this board has nice moog tones, from gritty bass to clear leads. i may get a moog liberation soon, but i definately plan on keeping the mg-1 as a backup. and for my money, the mg-1 beats the rogue because of its sturdy power cable and unassuming "realistic" name. with the mg-1, a little modesty goes a long way.

This synth is really easy to use. The moment you switch it on,
the sound generated is based on the settings that are visible on the
panel. I rather like this; since there is no memory in the unit the sound
will not change drastically when you turn a knob or slider so that it
"resets". If you have basic knowledge of what each slider is supposed to do
you will have no trouble using this. The only odd thing is that Radio Shack /
Tandy probably asked Moog to change some of the names of the sliders to fit
their market (i.e. the "Bell Tone", which is actually more like cross-modulation).
But again - this adds some uniqueness to the synth.

Polyphony: well - yes. But in a very strange way. You can have it set to
Monophonic or Full.

Effects: Just your basic LFOs for the Oscillatrors and filters.
No sliders or Pitch ben either, but frankly, it's no big deal here.

Expansion: No expansion capibilities but lots of room for mods if you're into that sort of thing.

Midi: HAHAHAHAHAHAHAHAHA!!!

Sequencer: HAHAHAHAHAHAHAHAHA!!! Sequencing.... Too funny.

By the way - I rate this an 8 because the features are really good
for what you get. However, dropped it down from a "9.5" because
some of the range in the LFOs and fileters could be a bit wider.

The expressiveness is suprisingly good. On the one hand, you're given
a very limited set of options to work with. But on the other hand,
this limited set lets you get away with quite a number of sounds.
I've been able to re-create theremin sounds right across the board to
speaker rumbling (sub) basses. Warm solo sounds can be accomplished very easily
and there is pleanty of room for nice Cutoff sweeps, etc.

Velocity/Aftertouch on these keys is too primal to really comment...

Yes - I guess on could depend on this synth.
Having said that, it doe not take much for this to have its glitches.
It's very sensitive to dust. Sliders tend to audibly sound gritty
and the portamento on my unit has this tendency to lock up on me once
in ahwhile. I have had this professionally serviced twice. However, I
sort of expect that from these types of units. This synth does require
quite a lot of maintenance overall but it sort of adds to the appeal
of this nutty little Moog.

I doubt any of the staff at Radio Shack would have any
idea what this is at this point. I only service it
with a few synth experts in town.

I got this as an exchange with a friend so in theory, I paid nothing.
It still serves me well and I would not sell it at any point.
If it were stolen, I can't say that I'd go out of my way to look for
another. I would probably look for a better quality Moog.
What I love about this is that I can switch it on and I'm off to
the races. I've had this over 5 years now and I find that I'm
always drawn back to its solo sounding features.

I wish it were a bit more stable and reliable since it has
needed more attention than any other synth I have. I like the
fact that is can be modified fairly easily. I have not done any mods
to my unit but I like knowing that these are all possibilites and are
not big or expensive tasks.

In the very near future, I'll be posting some specs and info on my gear.
Check it out here in the coming months:

You can't get more intuitive than a pure analog board. Being able to physically tweak dials and faders makes synthesis intuitive and tangable.

Compared to most Moogs, it may be seriously lacking, BUT for the price, it's amazing. I picked mine up for $75 in a pawn shop.

The 24dB filter is the #1 feature in my mind!

Having 2 detunable oscillators is great, but I wish the 2nd oscillator extended down an extra octave to match the first oscillator for better bass sounds.

The MG-1 is perfect for a raw, quirky sound all its own. It harkens back to a 70's retro sound, but works great for modern dance music:
-SWEEPERS ARE AWESOME!: With the 24dB Filter I can listen to them all day "BRRRRRRGHGHGH!!"
-I love playing leads on it. Intuitively, it's easy to switch octaves and change filter settings on the fly.
-Autotrigger- even if you can't have MIDI, flipping on Auto-trigger yields some fun grooves.
-If you don't use it for performance, it's a great sample source. I've sampled thick kick drums, basses, acid lines, blip-bloppy kraftwork sounds, and even thick pads and stabs to be played back polyphonically on my sampler. Remember, even when your MG-1 starts to age and become unreliable for performance, you can still sample it.

DOWNSIDES- The keyboard is stiff and sluggish.
-There is no pitch bend, BUT I'm comfy just using the tuning dial.
-I like using auto-trigger to create metronomic grooves, but the modulation rate control jumps too much, instead of being more incremental, so you can't really tempo match with it.

BAD POTS! It's a shame, because it's the only thing holding mine back. Of course the first one that went bad on mine was the Filter Cutoff slider, and now it's spread to 80 percent of them. Warning: Don't be a goober like me and spray the pots if they sound dirty! It will eat away at the felt lining quicker than you think.

TUNING AND MENTAL STATE: Mine held it's tuning OK for a number of years, now it's at the point where it starts to wig-out when I turn it on, and really just needs to warm up for a few minutes.

The result: I can't use it for live performance, but it still holds up as a studio board and a sample source.

I use a digital synth, a digital/analog hybrid, and a sampling workstation, so an all-analog board, with it's warm, robust, and wildly quirky sound is a perfect complement. When I first saw the MG-1 with it's Radio Shack connection, I thought it was a joke...than I played it...and snatched it up! For $75, it's incredible! I wish I had two...then I could sync them up and make a 4 oscillator synth to be reckoned with!

10...duh...this is easier to use than a casio sampling keyboard...this is like buttering bread for breakfast.

It's monophonic, with a polyphonic ovrlay that completely ruins the sound when used. Lots of sliders, lots of fun. CV pitch and trigger inputs...has an audio input which happens to Rock if you slap a capaciter between it's output and the filter input...moog filters sound good on ALL NOISES! Would like to add a midi upgrade...but i havent the 100 bucks to fork out for it.

Deep and rich...not expressive so much in play control...it plays itself. Just trigger one note repetitively, never sounded better. 2 oscillators...one able to go an octave lower than the other...saw and pulse shaped wavs for both...a nice lfo which even has a random option.

Horrible sliders...half mine crackle, wont stay in tune for more than 10 minutes...less if your REALLY playin it! Cheesy plastic Realistic casing of course. Not the usually nice moog wood grain.

Havent looked into it...

Great beginner's synth...a little misleading by the way the label things...I'm used to seeing Envelope Generator and resonance...not Contour and Peak Emphasis...but it dosnt matter...just turn knobs and have fun.

Knobs and sliders.

Read the others.

Not Bob's beefiest OSC's but worthy of the name based on the price.

Never a problem, even though I tried to make a MIDI interface for it and fused some hair DNA from my arm to the chasis when I touched the wrong wire.

I don't have Bob's number in the tropics.

Wish I had never sold it.

I'm experianced with synth gear. I've buzzed my self apart with great ease. It's nothing to fire that thing up on improv, walk up and down that thing all night, one hand on the sliders, the other on the keys, and vice versa.

The best feature is the CV and Trig. Nothing is better then an analogue synth that you can trigger with midi.

The Modulator is very smooth on my moog.. The contour is quick and evil. Nice range on the VCF.

Its a snake charmer, but that's it really. Fat bass, and really fast transitions.

The circuits and chassie are strong.
The Sliders (pots) are pure garbage.
I've dropped mine a few dozen times...

I am in the process of mounting the circuits in a new chassie, change all the sliders, and switches to high quality components. Also, I am replacing the power supply with a very low noise, highly stable setup. The keys will be remote and detachable. My Mods. should make this thing sounding perfect and much more stronger.

Basic Electronics 101 - At your local community college....

I have had more fun per square inch on this synth than any other synth I have had the pleasure of owning.

I love simple beautiful sound, and this little bad boy simply shoves it down your throught...Get one and sleep with it.

It doesn't get any easier than this: there's a switch or slider for every parameter. Analog baby.

It's monophonic, although it has an extra oscillator called "polyphony" which is fully polyphonic. Very strange. It sounds rather organ-ish. Of course, you've still only got a single filter and envelope, so it's not true polyphony.

Very simplistic architecure: 2 VCOs (syncable) plus noise source, the abovementioned polyphony, and an extra oscillator called "bell tone", AR envelope, LFO (tri/squ/random waveforms, routable to filter and pitch), osc mixer.

Bass is definitely its strong point. This thing can rattle the windows. Great for dub, funk, drum & bass, hip-hop. (Mine is mistuned 5 semitones below proper pitch. I thought about getting it calibrated, but I like having that extra bass range. I might even see if I can tune it an octave below :) It's useful for bleeps and acidish leads too, but overall its palette is pretty limited.

If you own one of these, READ THIS:

There's a foam dust screen just under the front panel which turns into a horrible, horrible black goo over the years. GET IT OUT OF THERE!! Pull off all of the knobs and slider caps, open the case, and remove the top circuitboard. You'll see the foam overlay. BE CAREFUL - it liquefies on contact, and it's very, very sticky. Rubber gloves are a good idea.

Mine has 6 broken keys, but then a cat pissed in it. I play it thru CV anyway.

Amazingly, I've never noticed any tuning drift. Whereas my Moog Source takes half an hour to warm up before it'll stay in tune, this thing is very stable.

I've heard that Radio Shack will still supply the schematics if you ask them.

I have a peculiar attachment to this thing. (Maybe not so peculiar, since it was my first analog.)

Though it's rather limited, it's a great choice for a beginning synthesist, or if you're looking for a set-and-forget bass box.

I really want to stuff mine into a rack unit. I don't know if I have the nerve to take a soldering iron to my precious little EmGee tho.

Nifty sliders for every function. How much easier does it get?
It's simple, it's easy.

has a ring modulator, and an "organ-ish" poly voice which I have never really used. Only two waveforms, triangle and square and an ASR envelope. Has trigger/gate in/out and has a line in that you can mix with the synth's sound with a little mixer in the corner. Unfortunately the line-in is not routed through the Moog's wonderful filters but there is a mod floating around on the internet that will let you do this. I've never had the time to actually perform this mod.
This beastie is pretty old, maybe 80 or 81 and it was a consumer end product, not pro-gear, sold exclusively through Radioshack (it was basically the Moog Rogue stripped down a little and repackaged).
I really wish it had the pitch-bend wheel on it, but you can use the master-tune knob in a pinch. This wee beastie has rock solid tuning an amazing feature for a cheap analogue synth of it's era.

Nice beefy bases, nice cutting leads. Great analogue synth sound. No velocity etc. The poly voice on it is not terribly usable but asa mono analogue synth you can do some really neat stuff with it.
The sound is also remarkably clean.

Well these things are prone to the problems that face all old analogue synths, the most obvious being dirty pots. Mine spent years being neglected in a garage before I rescued it from it's previous owner and tool a lot of TLC to get it functional again. But since then it has worked flawlessly although there are a few sliders I really should replace when I get the chance.

I hear you can still order photocopies of the manual from Radioshack but if you go into the store and ask about it they'll look at you like you're an alien that just asked if you could please anal probe them. Ask to see the special order catalogues and then look it up yourself. But really, this synth is so easy to use there's no need for a manual. Just sit and twiddle to your heart's content.

Well I traded a dead moped but this guy's dead synth and appearently both of us left the deal thinking the other was a sucker. With some TLC I got the MG-1 working again (don't know if the same happened to the moped) and all I can say is I'd take a working MG-1 over a working Moped any day of the week. It's a great beastie with a nice beefy sound and easy to use. I take it out to live shows and use it in the studio. They're not too hard to find since they were marketed by Radioshack and were sold as a consumer product and not a professional synth infact I would not be suprised if they were the most common Moog synth out there. This is good because apart from being easy to find this also means they're cheap. Although I got mine for no monitary value I have talked with very few MG-1 owners who have paid more than $75 for their machine and even at $100 I would consider it still an okay buy. Just be careful though, as with all old analgue stuff there are a lot of people that automatically think it's worth big bucks just because it's old. This is not always the case. The MG-1 is neither rare nor highly sought after which means it's a very cheap buy so don't let anyone bull-puckey you into thinking they're a rare, expensive collector's item because they arn't. But they are unbelievably cool and well worth $75-$100.

Very straight forward for an analog synth. Everything is done with buttons and knobs. Some of the terms on the front panel may be a bit misleading.

Has 2 VCOs that can be synced together. Unfortunately only triangle and square waves are available.
Has an LFO for VCA, VCO of VCF.
The VCF is exellent, controllable with ASR envelope. It can oscillate on its own, which is cool if you are using an auto trigger to sweep it.
The synth is semi polyphonic. The standard VCO section is Mono, but there is also an organ style polyphonic sound that can be mixed into the overall sound. CV and Gate input and output through a stereo 1/4 inc connector

If you like Depeche Mode' first two albums, then this is the synth for you, as far as bass is concerned. Cheesy Vince Clarkian leads are easy to do as well.
Not touch sensitve.

Rock solid tuning!!!!!

I just bought it. I've already used it in recording my next album.
I like it better than a Korg 770, Yamaha CS-10. It is a cool bass board, and makes great New Wave lead lines

Several switches and sliders make this thing pretty easy once you figure them all out but generaly it's pretty self explanitory. The keys are a little slow sometimes at triggering the notes but other than that just play and tweak your heart out.

this thing is monophonic unless you crank the "polyphony" slider which is like an organ section of the mix and enables you to play every note on the keyboard. the ring modulator ("bell tone") is alright and the white noise generator is sweet. no arpegiator though.

the filter is pretty nice. not great bass sounds but great special effects and tripped out noises. the autotrigger modulation is neat. the two oscilators are warm and detunable. cool real analog sounds for this price range.

seems pretty reliable but victim of the classic analog ailments. those tricky trigers are bad too.

good analog sound from moog and radio shack for a reasonable price. ($200-$300 should be about it) it's like a cross between a liberation and rogue
