Patchbay is a three-person studio in Rotterdam dedicated to repairing and restoring vintage synthesizers. Founded by electronic musicians who grew frustrated watching beloved instruments fall silent, we approach each repair with the reverence these machines deserve — not as collectibles, but as living tools for sound. Our bench has revived everything from corroded Minimoogs and temperamental Jupiter-8s to obscure European modular systems and forgotten Japanese curiosities. We source original components where possible, fabricate what no longer exists, and document every intervention so the next technician inherits clarity, not guesswork. Beyond repair, we consult on studio integration, design custom modifications, and run a small workshop series teaching synthesis fundamentals through hands-on restoration. We also collaborate with conservatories and museums on preservation projects, ensuring institutional knowledge doesn't vanish with the generation that built these instruments. The goal is simple: keep the instruments playing, and keep the knowledge circulating.
