Founded by Gianfranco Ceccolini in Brazil in 2013, MOD Devices — now operating as MOD Audio — is a Berlin-based company that builds open-source, modular multi-effects processors for musicians. The platform combines standalone hardware units with a web-based graphical interface, allowing users to drag and drop from a library of hundreds of open-source LV2 plugins including effects, amplifiers, synthesizers, and utilities. The company's ethos centers on community-driven development, with musicians and developers contributing plugins, sharing pedalboard configurations, and collaborating through an open-source ecosystem.

The company's hardware lineup includes the MOD Quadra (their first product, launched in 2013), the MOD Duo (funded via Kickstarter in 2014), the MOD Duo X (a more powerful unit unveiled in 2018 with a larger processor, more memory, and higher bit rate), and the MOD Dwarf (a compact floor unit funded on Kickstarter in 2020). All devices run MOD OS, a Linux-based operating system, and connect to a browser-based pedalboard editor for building and customizing signal chains. MOD Desktop extends the platform to computers as free, open-source software.

Notable users include Joey Zampella of Life of Agony, Sebastian Szary of Modeselektor, Trey Gunn of King Crimson, Tobias Jundt of Bonaparte, and Philipp Thimm of Apparat. The platform has earned praise from publications like Sound On Sound, which described the MOD Duo as "brimming over with potential."

MOD Devices has 2 products cataloged on Equipboard, including Multi Effects Pedals. Their gear is featured by 1 artist, with the strongest followings in Rock, Pop, and Folk, World, & Country. Notable users include David Ryan Harris.
