Critic Reviews

Realistic Concertmate MG-1 | Vintage Synth Explorer

vintagesynth.com

The Moog Concertmate MG-1 offers an affordable entry into Moog's world, boasting a genuine 24dB/oct Moog filter and simple interface, making it attractive for beginners. While it provides classic Moog bass sounds, its overall sound can feel thin, and it lacks MIDI and patch memory, limiting its modern usability. The slider-controlled divide-down polyphonic organ adds some versatility. A mixed bag, the MG-1 is ideal for those seeking vintage vibes on a budget, but may leave sound purists wanting more.

RadioShack’s Neglected Moog: Exploring the Realistic | Reverb News

reverb.com

The Realistic Concertmate MG-1, a collaboration between Moog and RadioShack, offers a unique twist on classic Moog synthesis with its quirky polyphonic features and robust Moog ladder filter. While it delivers strong bass and a versatile architecture, the use of cheaper components means it lacks some high-end polish. Despite the infamous sticky foam issue, which requires careful cleaning, the MG-1 remains a beloved favorite for its distinctive sound and modding potential. A budget-friendly entry into the Moog universe, it holds its ground against modern analog competitors.

Deep Dive Into ‘The Radio Shack Moog Synthesizer,’ The Realistic Concertmate MG-1 – Synthtopia

synthtopia.com

The Realistic Concertmate MG-1 is a curious piece of synth history, blending iconic Moog circuitry with a divisive polyphonic organ feature. While it delivers unique, sharp, and nasal sounds that some cherish, others find its minimalistic design and deteriorating foam off-putting. It's not the most serious instrument, but its quirky charm and distinctive sound keep it in demand among collectors. Though it may not replace more refined Moog models, its bizarre allure and ability to produce interesting tones make it a notable oddity. Ideal for those seeking nostalgic or unusual soundscapes, but not for everyone.

Deceptively powerful, Moog-powered, and very tempermental

For the basics, check out the Automatic Gainsay video series on the MG-1 (https://www.youtube.com/watch?v=qE7aQpA4XVA). It's very similar to, but superior to, the Rogue. Mostly monophonic, with two oscillators, a strange envelope, and a divide-down organ section for polyphonic play. It's harsh, the tuning drifts, and it can make disturbingly rude sounds. Really good stuff and still, imo, undervalued.

Mine is heavily modded by SwitchedOn in Austin. See the photo of the mods on my gear page. The mods allow me to drop it an octave, route either the LFO or ENV to VCO2, set the modulation amount of VCO2, route VCO2 to the VCF, set the pulse with of both oscillators, add PWM to VCO2, and set the modulation source to either the LFO or the ENV.

I don't have a MIDI mod, but the CV/Gate works great. In short, it's flexible, it's distinctive, and it didn't cost too much. It's a heck of an option for Moog sounds.

Awww I miss Radio Shack!

Thank you Bob Moog for selling out in your early stages. This little monster has some sweet spots that just scream "I AM A MOOG!!!!" I need to modify it with a midi upgrade, but for now it's chugging along using CV and is ding just fine. Still sounds great next to it's great great great grandson the Sub37.

Great synth with polyphony!

This really is a fantastic synth. It has 2 osc and 1 filter. It's pretty limited as far as waveforms go though, but it has polyphony! It came out in the 80s. I received it as a present from a beautiful girl at university called Helen. That was back in the early 90s. Today it has spent a bit of time in storage under the stairs where it turned out to be a bit damp, and it famously has this weird foam in the synth that dies and turns into goo after a while so 2 of the keys stick down. I should really open it up and see if I can clean it.

Radio Shack's Moog

Great little monosynth (After cleaning the infamous foam/tar under the control pannel), 2 Oscillators (1 detunable), 1 Enveloppe, Low Pass Filter, LFO (2 shapes), Noise, ''Bell Tone'' (Digital Ring mod) and.. POLYPHONIC section!! This feature makes it a 5 stars synth in my opinion, can be routed to the filter (And to the pitch with a mod).

good cheap moog sounds, very 70s sounding

this thing sounds incredibly cheap, in the best way possible. If youre looking for that 70s/early 80s budget film score sound, this is it. incredibly fun to play

oh man, I had one of these before anyone knew what they were, sadly she had so many problems creep up and the PCBs are so difficult to work on I wound up selling her for parts to a enthusiast/restorer:-( these things sound really neat, you're lucky to have a working one.
