Jolin is an audio electronics workshop based in Como, Italy, founded in 2018 by hardware designer Federico Intrisano and software engineer Pedro Ferragut. The project began with a first oscillator built on a breadboard in Intrisano's garage and grew into a small team that includes composer Marzo Zoppi, electronic engineer Giacomo Tombolan, and 3D artist Mihaela Costisanu. The workshop operates under the tagline "we build stuff" and frames itself as a lab sitting at the intersection of scientific rigor and artistic experimentation.

The brand's catalog centers on Eurorack modules and sound sculptures, with an emphasis on unusual, characterful circuits rather than conventional utilities. Releases include the TABØR rhythmic avalanche oscillator, the BE2N dual Benjolin, the GOBLET filter, the AGOGÔ octal low-pass gate matrix, the GITGUD bank of LFOs, the KRONO programmable clock, the ROSA morpher, the KNOBI macro controller, and the NEXUM cable tester. Modules are individually assembled and tested in-house before shipping.

Jolin is a regular exhibitor at modular synth events including Superbooth in Berlin, Machina Bristronica in Bristol, and Modular Day in Barcelona. The lab also runs DIY-focused workshops aimed at both newcomers and experienced electronic engineers, where participants build original designs as part of the session.

Jolin has 8 products cataloged on Equipboard, including Modular Synthesizers. Their gear is featured by 1 artist, with the strongest followings in Electronic and Pop. Notable users include Andrew Huang.
