Pulp Logic is a manufacturer of Eurorack modular synthesizer hardware, best known for inventing the 1U tile format — a thin utility module standard that sits above the standard 3U Eurorack row to make use of otherwise empty case space. The 1U tile format combines the Rack Unit specification with Doepfer's Eurorack specification, packaging a 4U system as 3U of Eurorack plus 1U of tiles, and has been adopted by a number of third-party makers. (Note that Intellijel's 1U format is a separate, incompatible standard.)

The company's catalog spans more than forty 1U tiles covering VCAs, mixers, attenuators, multiples, manual CV sources, and effects such as a spring reverb tile and a Princeton-chip delay, alongside 3U Eurorack modules, power and tile-carrier components, and Pelican-style portable cases like the Lunchbox Zissou LBZ42 and LBZ54. Tiles are sold both populated and as DIY-friendly products, with parts and rails available separately for builders.

Pulp Logic positions itself as "hardware for instrument makers," and its products are stocked by modular retailers including Perfect Circuit, Signal Sounds, and Pusherman Productions, as well as the company's own Etsy shop. The 1U tile standard has become a common way for Eurorack users to fit utilities, I/O, and power into compact cases without sacrificing 3U real estate.

Pulp Logic has 8 products cataloged on Equipboard, including Modular Synthesizers.
