Moog Music today announced that it is reintroducing the Moog Modular Synthesizer IIIc system.

Like the Emerson Modular System and the Moog Modular Systems introduced in 2015, the Moog Modular Synthesizer IIIc system is built using the original documentation, art, and circuit board files and wherever possible, new-old-stock parts. 

Each instrument features thirty-six hand-stuffed, hand-soldered modules, including ten 901-Series audio oscillators, the 984 Matrix Mixer, and the 905 Spring Reverb. All modules are mounted into two hand-finished, solid walnut console cabinets at the Moog factory in Asheville, NC.

“It’s a privilege to build instruments in this way,”says Moog Production Engineer Anna Montoya. “It lets us reimagine what future tools can be. There is so much potential in this history.”


  • Limited edition of 25 systems
  • Hand-wired using legacy parts and original assembly methods
  • 901-series voltage-controlled oscillator
  • Meticulous re-creation from original documentation, circuit board schematics, and art files
  • Handcrafted using traditional manufacturing techniques
  • 36 hand-stuffed, hand-soldered modules custom mounted and hand-wired in two hand-finished, solid-walnut cabinets
  • 10 discrete 901-series oscillators (Moog’s earlier, less stable design – not found in the later System 55, System 35, or Model 15)
  • 905 Spring Reverb module
  • 4 x CP3 mixers
  • 984 4-channel Matrix Mixer (for parallel processing, includes dedicated bass and treble controls)
  • 100% discrete design (no op-amps; not true of System 55, System 35, and Model 15)
  • Built and behaves exactly like the original; exhibits the tuning instability and interference susceptibility inherent in the design
  • Includes patch cables; 953 Duophonic Keyboard Controller available separately
