Pittsburgh Modular Synthesizers is a builder of analog electronic instruments founded in 2012 and based in Pittsburgh, Pennsylvania. The company was started by Richard Nicol, with longtime collaborator Michael Johnsen leading analog research and engineering. Their output spans Eurorack modules, modular cases, and self-contained semi-modular instruments, with a design ethos that leans toward exploratory, hands-on synthesis rather than preset-driven workflows.

The company is best known for its semi-modular desktop instruments, including the Microvolt 3900, the Voltage Lab 2, and the Taiga — a three-oscillator paraphonic analog synth with cascading waveshapers and six-stage wavefolders that has become their flagship. Pittsburgh Modular also produces the Structure series of Eurorack cases and a catalog of individual modules covering oscillators, filters, function generators, and utilities, much of it built around their characteristic resonant lowpass filter and chaotic CV designs.

The brand has carved out a niche among modular and West Coast-style synthesis enthusiasts who favor instruments with unconventional routing and harmonically rich, often unpredictable behavior. Their products are sold worldwide through their own webstore and a network of authorized retailers.

Pittsburgh Modular has 68 products cataloged on Equipboard, including Modular Synthesizers and Synthesizers. Their gear is featured by 12 artists, with the strongest followings in Electronic, Rock, and Pop. Notable users include Andrew Huang, Funkagenda, and Virtual Riot. Pittsburgh Modular's catalog spans the full price spectrum — from entry-level options to high-end flagships.
