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 and one workshop in Rotterdam, and we spend our days bringing old synthesizers back to life. Most of what arrives at our bench is somewhere between thirty and fifty years old: a Juno with a dead voice chip, a Minimoog that drifts out of tune the moment the room warms up, a Polysix whose battery has quietly eaten its own circuit board. We know these instruments inside and out because we have had hundreds of them open on the table.
We started Patchbay because we kept meeting musicians who had been told their synth was not worth fixing. We disagree. These machines were built to be serviced, and with the right parts, enough patience, and a good set of schematics, almost any of them can be made to play again. When we hand an instrument back, we want it to sound the way it did the day it left the factory, or better.
