About

Patchbay is a three-person studio in Rotterdam, dedicated to repairing vintage synthesizers and keeping them in use.
Old instruments have a way of becoming familiar: the feel of a key, the response of a filter, the particular sound a circuit makes when it’s working as it should. When something goes wrong, we take the time to understand both the fault and the instrument around it. We work carefully, preserving original parts wherever practical and making repairs with the long term in mind.
Our studio brings together a shared interest in electronics, sound and the machines that connect them. Whether a synthesizer has a stubborn key, a noisy output or has been silent for years, we’re interested in finding a way forward.
We work with musicians, collectors and anyone who wants to hear an old instrument come to life again. If you have a synth that needs attention, we’d be glad to hear about it.
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.
