About

Write the opening of the About us page for Patchbay, a three-person studio in Rotterdam that repairs vintage synthesizers. About 150 words.

Welcome to Patchbay. A dedicated three-person studio in Rotterdam, where analog warmth meets modern precision. Our workshop is a sanctuary for vintage synthesizers, circuit boards, and forgotten sounds. We operate on the belief that vintage gear deserves respect and careful handling. Every unit we restore is given a new life, preserving its unique character while ensuring it functions reliably. We work meticulously on instruments that shaped electronic music history. This isn't just repair; it is resurrection. Our artisans take the time to solder every connection and clean every capacitor, understanding that imperfections hold stories worth keeping. We aim to keep the legacy of analog synthesis alive. Whether you need a fix or advice on your collection's condition, we support the analog revival. Trust in our expertise to get your dreams humming again. In a digital world, we choose to sound the truth. We believe in the tangible sound of history.

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.
