Built by Moog for Radio Shack's Realistic brand, the Realistic Concertmate MG-1 is a cheap and simple two VCO synth with a genuine Moog 24dB/oct filter. Compact but powerful, the MG-1 is capable of summoning that signature Moog bassline and has found a new audience with acts like SURVIVE. Although a budget instrument in their day, the popularity of Moog has made them more collectible over time.
