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 is three people in a narrow workshop near the Maas in Rotterdam. Every day we open up instruments that were built before most of their current owners were born. Some arrive in flight cases and some come wrapped in old bath towels. Most have a story: a Juno that went quiet halfway through a gig, a Minimoog left in someone's attic for thirty years, or a modular system that a previous technician gave up on.
We started Patchbay because we kept seeing good synthesizers sent off as "unrepairable" when all they needed was patience, a schematic and a steady hand. We swap out dried capacitors, hunt for intermittent faults, recalibrate oscillators until they track properly again, and source or rebuild parts that stopped being made decades ago.
We don't try to make old machines sound new. Our job is to make them sound like themselves again, and to make sure they keep working for the next person who plays them.
