Momo Modular is a small-batch Eurorack synthesizer builder based in the San Francisco Bay Area. The operation specializes in professionally built, hand-assembled versions of popular open-source Mutable Instruments designs, produced by an electronics engineer with over a decade of experience. Modules are offered in full-size and micro (Antumbra) formats with panels manufactured by Magpie Modular, and builds ship with a one-year warranty.

The catalog focuses on faithful reproductions of Mutable Instruments modules whose original production has ended, including Clouds (granular texture synthesizer), Plaits (macro-oscillator), Rings (resonator), Marbles (random sampler), Peaks (drum/function generator), Grids (drum sequencer), and Elements (modal synthesizer). Micro variants such as uGrids and the Antumbra CARA and Atom redesigns offer compact alternatives for smaller cases. Modules are sold through the brand's own storefront as well as Reverb and Etsy.
