About
Write the opening of the About us page for Patchbay, a three-person studio in Rotterdam that repairs vintage synthesizers. About 150 words.
Patchbay is a three‑person workshop rooted in the heart of Rotterdam where a shared passion for analog sound meets meticulous hands‑on craftsmanship. Founded by longtime synthesist‑technicians who grew up chasing the warm, unpredictable tones of classic machines, we treat every instrument as a living piece of musical history. From the battered faces of 1970s Minimoogs and ARP 2600s to the rare circuitry of vintage Japanese modules, each repair begins with a careful diagnosis, the sourcing of authentic components, and a respect for the original design philosophy. We document every step, communicate openly with owners, and strive to return each synth to the character that inspired its acquisition while ensuring reliable modern performance. Our blend of technical precision, artistic intuition, and transparent service has helped artists across Europe keep their rigs alive, preserving distinctive voices that might otherwise be lost to time. Patchbay is committed to keeping analog synthesis thriving for future generations through integrity, skill, and a deep love for the sounds we resurrect every day.
Patchbay began the way most repair shops do: with a broken synth, a stubborn owner, and a soldering iron that refused to stay idle. We're three people—Joris, Marit, and Tomas—working out of a small workshop on the back streets of Rotterdam-Noord, surrounded by oscilloscopes, spare parts, and instruments that sometimes arrive in worse condition than their owners admit.
Between us, we've spent decades repairing and restoring vintage synthesizers: Rolands, Moogs, Korgs, Yamahas, and machines whose manuals were never written in the first place. We don't sell anything. We fix things. That focus keeps us honest and keeps the work slow, careful, and done properly.
We believe old instruments deserve to keep making music, not gather dust in attics or fetch prices only collectors can pay. Whether it's a cracked keybed, a dying power supply, or a voice that's gone quiet, we'd like to help bring it back.
